Thank you sir for taking the time to make this in depth video. The video was clear and not shaky. I appreciate it.

Good video Glen. I have jump many of the old Ford solenoids like that over the years !

This is the best video I have ever seen on starters and solenoids. Thanks. Knowing what poles to cross to start the vehicle is what I needed to know.

Nice job Glen, new parts have caused a lot of extra of work sometimes.

Thank you... You explained everything very clearly and didn't over explain things. Your video helped tremendously thanks again

Symptoms said mine was suspect too. I landed on your video, same make year/model. I think the best advice was just getting the oem replacement. Exact match. Fixed. Thanks, great content!

Good diag Glen and explanation 👍

Thank you. I like how clear and simple you made it look! I will fix my truck and share it with my friends.

Thanks Glen. Very informative! Always keep it to one hot dog.

wow thank you very much!!you saved me lots of money and it was so easy to check and replace. a mechanic wanted 150. just to check it out.

hi! i just saw your comment on TubeBuddys video and decided to stop by! Awesome content! Keep crushing it ❤️!

Thank you so much!! I have been trying to figure out what's going on with my 1994 Ford E350 club wagon with the inline 6! THANK YOU SO MUCH 👍

Thanks for the awesome video. My wifes been having problems with her 1998 F150. Sometimes it'll start sometimes it won't. I tested the solenoid and bam. Problem identified. THANKS!!

Great video! Finally a well explained correct video on starter solenoid relay replacement!thank you 🫵👍 🇺🇸

Yes, I’ve gone through the same thing over the years. One observation is that the negative terminal on the solenoid that you referred to is actually the positive terminal coming from the battery. Where the other terminal will still be positive going down to the starter motor. Great video Glen and should help folks to be aware of inferior parts.

Brother Dan did a remarkable job in the video, starter relay and voltage regulation.

I'm going through the same thing to on my 2001 ford f-150 xlt 5.4 v8 tritón. I'm going to go ahead and do that, by the way it was a great video and good presentation step by step which that's the correct way to do it, some just show you but some don't explain step by step and taking their time. I really appreciate you showing this video and I'm pretty sure others out there appreciate you to. Thank you

Thanks from the desert

Good to see you glen

Great video. I appreciate the detailed narrative

I had an intermittent start (click then would grab) for awhile then it just wouldn't start at all, just click. I followed your steps and noticed when I checked between the positive battery and the negative solonoid it would show voltage, but it was fluctuating up and down. Then when I jumped the solonoid it just clicked, no start. I was about to go buy a new solonoid and new starter when logic kicked in and I thought that I must just not be getting enough power. So I started tugging on wires and the positive cables pulled out of the terminal. I took it off and flattened it a bit to be tighter, re-installed and it cranked right up. Saved me alot of time, money, blood, sweat and tears. Thanks.

Excellent video in a way that's easy to understand.

I Appreciate your video I changed mine while watching your video and found a problem that i already had when I bought my truck a few months ago it was wired completely wrong so thanks keep up the good work saved me some money

Thank you for the tutorial, it fired right up after I replaced it!

Great Video, I just bought a 1988 ford ranger, that won't start, your video gave me, some good tips to fix that issue myself, I will provide an update if I could get that issue fix.

Awesome video! The negative terminal you mentioned is really being pulled to chassis ground through the starter solenoid coil so its technically not the same as the negative on the battery. Measuring the resistance of that terminal to chassis ground will show tens of ohms. In your video, measuring 12 volts confirms the coil isn't open and is a good check to do.

Awesome video man! FYI, that's actually starter relay. To the best of my understanding, it helps crank the starter so the battery doesn't drain

Love the SLOMO socket fail... Awesome info friend!!!

Great video glen and Yep on New "Never ever Worked "

From a shade tree mechanic this video was very helpful. Great job explaining everything.

Awesome video. Big help!! Thank you

You are a life saver plz continue making amazing content

Thanks, that was a big help. Mine is a 2002 but it's the same solenoid. luckily mine quit in the driveway not at a store.

Great video , I'm going to have to go check the other test videos too .. my old girl's been having some issues.

I love the song in the End. "Billy Jean". Awesome. 😅

You are very good mechanic and you explain very clearly I like you videos thancks friend

Good vídeo that help me alot!!

FYI, in the old days, the additional post on the aftermarket solenoid was used to send 12 volts to the ignition points, allowing a hotter spark on startups. Thank you for sharing.

Helpful video!!

Great explanation. Thanks.

Muy. Buen. Video. Amigo. Felicidades. Me. Ayudo. Mucho.

Great job 👏

Good video, thanks a lot

Great vid Presented well Thanks

Good Videos clear Information Thank you

Excellent video thanks

thank you mister ,you saved me lot$$$$ of money

Today I just went through the same thing you did with the starter solenoid. Ended up with the same "NEW" design that didn't work. Going to order one online now.

Excellent.

nice video , i cant imagine how many starters have been changed on cars that have this design and the problem was the solenoid .

Thank you for this video. I see you have problems too.

Like how you explain an check, I have a 1996 f150 ,

very good video

The deez nuts joke made me like the video😂😂😂 great stuff. Thanks for sharing your knowledge

Would you rather have the new Solenoid never Hot or Always Hot? A few years back I went through an old friend of mine’s Ford 8N Tractor. It Needed all new electrical from sitting 8 years, do it once, do it right was the plan. I Got a new solenoid from the local New Holland dealer, made in China. I get everything in order, all excited because this was the last piece. I hook the battery terminals up and the engine starts to turn over! I triple check the key, wiring, double trace everything since it’s Positive ground and a new format for me. I’m completely stumped! The Next day I stop at Tractor Supply and buy one made in Taiwan. Put it in and works like new. China vs Taiwan vs Mexico

Nice video keep it coming please

For those who are replacing a fender mount solenoid- be prepared to horse around the thick cables to match up the solenoid 8mm holding bolts

I just put on one of those 4-terminal relays today. Relay clicks loudly, but starter doesn't crank very often. Same problem I started with. Now if I jumper the two large copper terminals, the engine cranks every time. The 12VDC to the relay is good as the relay clicks loudly regardless whether the starter cranks or not. So it must be junk. I admit I`ll have to confirm this. Interestingly, the box said Made in China, but the plastic bag inside said Made In Taiwan. Plan is to do more testing and also take my old Ford relay apart, clean the contacts, and then try it. If it works, then I`ll know to buy a new Ford relay. I also noticed that plastic part interfering with getting the heavy cables on. The new relay came with spacers, but they don`t raise the cable away enough.... the plastic is still in the way. I didn`t check, but I think that 4th terminal connects to the coil (+) on older cars. It provides 12VDC during cranking which essentially bypasses the ballast resistor to get max battery voltage to the coil during starting. If that`s the case, DON`T ground it!

I had an Evenrude with a Ford solenoid. When it went south I made a mistake of buying a wing wang brand and it lasted about 1 month.

Thank you ive replaced my battery, then my cables from the starter to the battery , alternator and the starter. Just to watch this video and see it was my solenoid😂 thank you for sure

Whenever I say, "I'll get it later ...", I forget I dropped it, and spend 40 minutes cursing trying to find it (usually a 10mm ...) the next day! 😂 Broke When Delivered strikes again! I've got a Ford solenoid story for ya, Glenn! :D So, I bought a Motorcraft one from RockAuto back in 2016 for the Grand Marquis. I had just replaced all 3 battery cables, plus installed a new Remy starter. Put the Motorcraft one in to replace the 10 year old (at the time) one I had bought from Autozone (can't recall the brand). All was well - that starter whipped over faster than I had heard it in years! Then one day I was sitting on the can as my wife went out to go to work. Window was open (which happens to face the garage)in preparation for the nasal assault. I hear the starter crank ... and crank .. and crank! Thankfully I hadn't started my business yet! I flew out of there 100 MPH, just about knocked my wife over as she stood holding the keys in disbelief, and yanked the negative off the battery! I believe I was a victim of the 'rock auto switch' again. You have to pay close attention to what you're getting, regardless of what the box says. I've been burned SEVERAL times by this over the years - the past 5 in particular. I think I got a Motorcraft box, but some other substandard part inside the box. I ended up putting that old Autozone solenoid back in, and it's still working today - 4 years later. 😎

Just did mine ended up getting a new starter all so I needed it to be trustworthy

Diagnostic Glen eh :) I sure wanted you to test the lower stud on the bwd to see if it energized the relay 🤣 I've lost a flashlight under my Chevy truck and still never found it . HAHAHA

Best video ❤

Very professional video (wish all DIY were as clear w/ instructions). So, I'm having intermittent starting issues and when I tried the ignition test which you begin to show at 8:00 - it fails, there's no light on my test probe. My ignition fuse is still good so what does this mean exactly? Could this ignition cable itself be bad?

Grasias por la clase

Hecho en México nice

Jesus led me to this video in the middle of my travels. Godbless you brother and thank you God thank you Jesus Amen

Good job... I have a 98 Ford F150 4x4, automatic transmission, but I have a big problem with it, the 4x4 it doesn't works, the windows doesn't works sometimes either, I hope you can help me whit those things, it's been really stressful, I've tried changing the module that it goes into the fuse box, but still not working

Excelent help me with my truck

Distributor pick up coil could also be an intermittent problem like this. So, if this doesn't work that's the next part I'll buy. Good video ,it helped. Changing out started solenoid tomorrow. Bought the cheap one at auto zone for $24. Hope it works. Didn't want to wait two days for amazon plus spend another 10 or so. My 94 fordE-250, did an intermittent no start, no nothing to me twice already. Third motor, 4.9 ,rebuilt trans once and has 305,000 miles and still going. Owned now for 20 years.

My 1996 F150 has been giving me a headache with its starter solenoid. I swapped out the original OEM part with a Duralast (which resembles BWD) last week, and although it initially worked fine, it's now acting up again with intermittent starting problems. I'm leaning towards opting for a Motorcraft replacement.

The negative terminal you referred to is actually a positive terminal coming from the battery and the other positive terminal is for going down to the starter motor

Thanks for a great video sir, very precise and in depth. Question????? When you were bench testing the solenoid using a negitive battery cable clamp, why was it sparking on the ignition pole/rod?? Just wanted to clairfy was it the positive side jumper clamp to the base? Thank you very much. Appreciate your video and teaching! Cheers from Motown. Oh, New subscriber too. Thanks Glen

Interested in the wiring if there are 2 solenoids.

hey bro, just got my e150 back with a new solenoid and it was wired up the opposite way round!? was working for a few days now it's clicking once when i try to start it.... Gonna wire it back up the right ay tomorrow see what happens... any thoughts would be appreciated... cheers

The small bottom post isn't a ground. It's hot while cranking.

The first test you do around 4:45 (positive battery terminal to left post on solenoid), if you dont get voltage, what do you think the issue is? I previously had voltage, replaced the solenoid and starter, and still didnt start, not upon checking this again I no longer get voltage on that test. As far as I can tell, my grounds are fine, relays are fine, fuses are fine, and connections are clean. I just get 1 hard click when trying to start followed by a smaller soft click somewhere else. Battery reads proper volts and wont start with jump pack.

Wonderful video. Wish I seen this before I changed my starter! Did a drop test on the solenoid and it never gets to a stable number. Jumps all over the place! Does this mean it is likely gone? It will spark but not jump when I try to start it.

Ok I’m working on a 2012 f250 6.2 gas.. the guy at work said once in a great while it will start with the key and other times had to crawl underneath and jump the solenoid.well today the starter Bendix went out. So got a new starter cleaned all the connections put it all together and nothing still.. I have power coming to the starter main wire but when the ignition is turned the s terminal doesn’t get juice.. is it the ignition or neutral safety switch? Or something else..

You bad I like it

Truly helpful if i knew better id do better

Hey how you doing, anyhow I’m getting 12 volts on the positive but when tried to jump the two together I get nothing. Also I went down below and there is power going to starter when I jumper from the bottom I just get a wining sound

Same problem. And I replace the starter done deal

Lol did you say anti sneeze! I might even heard wrong and I know what you're meaning but made me laugh

Ford Edge 20xx wont start, theft led blinking. Disconnect battery then try again. WORKS!

When I try to jump my starter it sparks like crazy and a lot is that a sign that the starter is no good?

11* weather in michigan but when i go to start i cet a click. when i try to jump solenoid i get nothing. there were NO SIGNS prior,wedensday it worked,thursday morning it didnt. maybe the starter froze? or just took a crap? idk. you have an awesome informative video but theres nothing between solenoid and starter is there? its 5:50am and im searching the internet to push off going out in the cold. please tell me to jab the starter with a broom stick a few times lol gotta build a barn

Glen I know this is an old video but I have the same truck with a very similar problem 1 out of 10 times no crank hear the relay have positive crank signal at the firewall solenoid I was positive it was the firewall solenoid here’s my dilemma if I wiggle the signal wire on the starter solenoid on the actual starter I get a solid crank and fires right up side note when I have the accesories on the radio for a extended amount of time (waiting for my son to get out of school) it will wig out either act like the battery is dead or over engage the starter I just don’t want to throw parts at it as starters for our truck are insanely expensive nowadays. Wanted to know your thoughts

I’m currently going crazy trying to fix my 95 ford 350. I changed out the starter solenoid, I bypassed the solenoid and it runs. But i don’t have the tool to see if i’m getting voltage from the wire to the ignition which i think I’m not. I hear the relay or something click when i go to start it tho.

They’re both positive terminals. Check for 12 volts from the key switch first.

i just bought a 97 4wd f 150 4.6 , it been having 4wd issues no going back into 2wd, so i was troubleshooting it with vehicle off and I pulled the 2 4WD vacuum solenoid hoses pretty close to the starter relay, when i pulled off the one there was a big whooosh of air sound, then i went in to start the truck all i get now is a loud clunk sounds like its coming from around that relay area , no crank but it has a couple times tried to turn over for 1/2 second out of 50 tries.. battery is testing 12.5 volts. could it have blown a fuse when i did that or does vacuum have anything to do with it starting?

I always assumed the Ford solenoid was hooked up to a starter with no solenoid at the motor. Now I'm confused. Why even have it? Do those heavy cables carry the signal line for the starter solenoid at the motor? I was surprised to learn that the signal line for a starter motor carries quite a bit of current as well, often ~ 15A for a few seconds. Maybe this allows current going through the ignition switch to be reduced by a using second relay.

I have a 99 navigator and the solenoid was rigged up with a button until it got changed and the wire sparked and ended up getting hot and melted apart. So I got the replacement like you, then ended up getting the og part. But still no start even if I use a screwdriver it’ll just click. I’m going to try replacing some fuses to see if that works thinking when it sparked it might’ve blown certain ones. Any idea what else it could be if not fuses?

I used to have a '77 LTD that would go through solenoids every few months. I just kept a screwdriver on standby.

👍

If you verify your starter motor brushes are still good is it worth it to replace the solenoid or should You just replace the whole starter? Why do fords have a relay under the hood then another solenoid relay on the starter?

New motor craft defenitly sounds louder the the old one taken out the truck
