Great video for the people trouble shooting and its easy to learn if you can see it instead of reading a manual with just a couple pictures

Brilliant explanation - thank you. So helpful to understand how this works

Best illustration I've seen ! Thanks.

Knows alot about cars and troubleshooting...but a good artist as well...watts life...Major!

I'm not a mechanic, but need to understand the concepts for work. This was very well done.

Nice and clear 👍👍 I’m trying to diagnose a slow/no start and sometimes starts up with ease on my Yamaha Zuma. Battery checks out fine and jumping off my truck has the same issues

Informative to those who don’t know engines. Thank god for the 10 second skip option

Bravo!!.. Great chunk of knowledge with a clear delivery... please continue making instructional videos.... the world needs you!

Thank you Pro-MECH this video was so hlpful.

The small wires corrode first @ the battery, the most. 70 percent of that 80 you provide in the video. I frequent the junkyard and have seen thousands of batteries wired in many different configurations. if resistance is the enemy, corrosion is its financier. I took your class back in 2001.. you are a fundamental instiller. I credit your influence as one of my foundation stones of learning. thanks again.

Nice video. The reason for a bigger relay switch is because the relay on the cranking motor requires more current to run that motor. The connection between the motor relay and the cranking motor and to battery are thicker. You always need thicker cable to carry high current. This is why you always check the connection in this area for issues. You don't want exposed wires or loose connections at all. Anything that has moving parts, would eventually fail.

Perfect teaching , thanks A lot 👍

Excellent video and very clear and easy to understand

Best illustrated digression ever

I like these illustrations, very good learning tools. I hope you don't throw them away.

excellent explanation thank you

Old School it's forever !!

This is a great way to show how to work on cars

Dear Mr. Sullivan, thanks for the great information. Have just purchased a Loadpro and would like to ask how I can test the cranking motor on a Porsche 997 with slow crank. Do I have to remove the cables from the starter to test if there is any resistance in the cables or can I do the test with cables attached? Help much appreciated for an interested amateur like me.

hi wonderful lecture thank you

By referring us to a multimeter you have saved many hours and $!. Very basic and common sense for those aren't able to understand. A well thought out diagnosis video. WWG1WGA!!! 🇺🇸🇳🇫🇺🇸

Y all the art class

very good information

thanks for sharing!!! hopefully i can use this Knowledge to Crank my p30 1988 chevy 454!!!!

I miss your content. I hope you're doing well. I have one of your DMM tech kit with book. I've learned a lot from you, especially the thought process. Would love to see more electrical diag videos.

So genius, you’ll never know unless you know

Interesting video!

Look at this fellow's hands. Now THAT is a guy that turns wrenches!

I love the honesty. it gets very confusing. lol.

Nice job!

Forget it never mind ..GEEZ !!!

Best way to learn for myself anyways thanks

Somebody was in the military. Lol

Excellent video

Cranking motor is correct terminology = even going back to the 1960s where cars had a cranking motor- many were designed with the ability to be started using the trusty crank handle --- This ceased to be so with the advent of automatic transmission. These days also it would be difficult to turn over an engine using a crank handle given higher compression ratio than what use to be and vehicle electronics complicating the matter even further. A car battery would suffer in very cold weather conditions - such as freezing cold - particularly when not used for a few days -- Thus being able to start the engine by manual cranking saved the day - and no need to spend money exercising at the gymnasium - manual engine cranking was excellent exercise .

Its art class

Yes indeed that is hilarious you said that

It's like a drawing lessons.

Dude I love you hands . I have the same hands . But I just started wearing gloves after 30 years and what a difference .

Help. My miata one day stalled out when I put the clutch in on deceleration, but I was able to bump start it back to power, however it started making knocking sounds and had no power at all and eventually I stopped and wasn't able to bump start it again and it would crank really slowly but it wasn't battery because I had replaced the alternator 6 months ago and also jumped the car and tried cranking it and it still would turn over ridiculously slowly. I also heard a bit of knocking at around 3k rpm a few days prior but it went away as the RPMs increased. Is this piston slap? Bent valves? Broken oil pump? Bent valves?

Do you have a wiring Diagram on a 2006-2008 hyundai santa fe/ How to check a relay to a starter on a hyundai santa fe

Within 42 seconds - I have a question relating to a statement you made. Explain the difference between ; Won't do nothin and won't do anything ? and what happens when it WILL do nothin ? Where did you study your English ? Was it an accredited school or were you just incompetent student ?

You should be the next blues clues guy on tv lol thanks for the vid

Is it possible to increase cranking time?

Love the art... keeps things clear (even if it takes awhile...). But I'm getting thrown off by the mixing of solenoid, relay, switch. All "switches" but solenoid and relay are different pieces of kit and function in slightly different ways. Thanks for doing this!

I wish I could draw like that.

thanks dan

Well done sir

How to be an artist 101

SO if my ground wire is greening at the end perhaps I should replace?

Why the starter works when you bump it ,Is that the solenoid problem not the motor?

Watch on 2x speed.

Hey, R. Muckle! When you say "Vehemently disagree that 80% of the time it's wiring!! Almost ALWAYS it's corrosion and or dirty battery terminals" you are agreeing that is a CABLE ISS:UE unless you mean a dead battery! Anyway, Wow! Thank you, Dan! Very detailed explanation, you are a great teacher, really! Best breakdown of the whole deal I have ever seen.

Hey Dan, I have two questions. Are in Canada, and do have a brother named Micheal who is an eye doctor? Because I have a snowbird customer in Az from Canada that could be your brother....just thinking small world and all.

I've got both problems. Cranks once, that's it. After that, turn the key and no crank. New battery, full charge. After crank once, have to charge battery to get it to crank once again. UPDATE 5/30/18 - checked every circuit for parasitic draw. nothing. turns out it was the alarm system. if we don't use the alarm, the battery stays charged and the car turns over and starts with no effort.

Skip to 4:00 thats where the info starts

excellent explanation. you must have minored in art, because your drawings and handwriting are neat and clear

No, it's a spinning doohickey that spins the crankshaft whatchamacallit instead of using the crank handle thingamabob.

It's designed to start the engine you start the engine by turning it over

I need some help... I have a 69 C10 and I go and start her up and doesn't crank over. I turn the ignition again to no avail and when I attempt to pull out the key it's still cranking without the key in the ignition. Battery then drains after five or so minutes. Can you help me find the culprit here not really a car guy. Bad switch? Bad starter? Bad relay? Alternator? Thanks,Joe

Hi, would a bad starter cause a sudden stall at a red light? And cranks but no start afterwards? Thanks

hey, i have a 350sbc with headers and flowmaster exhaust. it starts fine when cold. cranks normally. but after its warmed up it wont start (heat soak i know) but i have a heat wrap around the starter. (starter is also a pmgr mini torque) i Just replaced the battery because it was old and needed changing anyways but i assumed it was the issue. im still not able to crank when cold. my grounds are good. only happens when hot. please help :/

Is a starter solenoid the same as a cranking motor solenoid

Oh my word, McDonalds must be layin off

I have been working on cars for 40 years and not once,not even from an old timer have I ever heard anyone call it a cranking motor.

I tried to program my key for my 4gen odyssey but failed due to this gen can only be done in dealership with special tool. Then days later my odyssey quit on me while cruising in town. Now it's towed and I manually charged up the battery to around 12.8v and tried to crank. But I only can hear is click, a sound like a breathe in click and that's it. No crank at all. Sir, do you think it's related to the relay or fuse or anything else. The van was running like a champ before it stopped. Any ideas that you can share? Thank you and hope you will read the comments too!!

I feel like I'm watching Kahn Academy for cars...

My vehicle slow cranks only after I use it. I replaced the starter and still same result. I let the vehicle sit for about an hour after use and it starts fine. Any advice?

Yep probably should of watched this earlier bc my car has a slow crank when it sits for more then couple of hours. But when I drive it and restart it say like 15 mins it starts up fine. So I went to advance Auto parts to run a test on alternator and the guy said it's my starter and that my battery was full power. So just got my new starter put in and still did a slow crank after it sat for couple of hrs . Any ideas of what it could be?? I thought it was a fuel line problem from the beginning bc it starts fine if it's been on and I restart it with in 45 mins.

I have a not start and no crank only my 2002 Ford Explorer sport trac 4wd but I connected a wire from the battery to the starter and when it makes contact with the negative it turns on so the starter shouldn’t be the problem nor the motor so could it be the cable from the battery be bad or the ignition switch ?

It's a starter or ground problem 99% of the time

20-12-2018, yes lovely video, but, NOTHING_ NO CRANK, for me was fixed, by ( in the middle and the shopping centre cark park)(no previous problems) was fixed by removing the battery clamps, cleaning clamps and terminals with a KFC hand wipe, and WOW it started,

Lol I only found it hard when u said it

so where is part 3 of , No Crank - Slow Crank

I think you just like drawing it while u explain lol helped me tho

I just googled cranking motor for 1974 super beetle. The first result showed pictures of an actual engine motor. The rest of the results called it.....wait for it a STARTER. I have a 1974 VW beetle. the engine CRANKS over really slow sometimes. I wish someone would tell me how to fix it.

i have a ford 3cyl diesel tractor just the other day it decided not to start ,,, i put a new starter on it and a new battery ..and i bypassed the wiring after no success and just started a simple hot wire right off the starter ,,new battery and starter as i mentioned and it cranks so slow it would never start and it doesnt ,, been working on it for a week and right at where i started ,,, tractor never ever failed to start on me before ,, now its useless ....any ideas as i said bypassed all the wiring just to try ,,and nothing ,,, its a 4000 series tractor industrial with 6 foot bucket ...

none of my teachers could explain it better than you.

If the starter has a solenoid/relay on it then why is there a need for the starter relay?

Summarize... 80 percent of faults is in the wires and 20 percent is in the components. Got it.

This guy is the epitome of what is a bad teacher

Can the starter be the cause of a parasitic drain?

I fell asleep lol 😂

So... Slow crank because factory put "Lots of wiring in there" ??? There is a second part to this video guys! Let's watch it now.

Just coudn't take it anymore......

We're close but no cigar

Cranking motor, FOH im gonna call the throttle pedal a “manual input lever for initiating an electrically powered,sensed and compensated air inlet valve”.

Wake me up...... When September ends....

Is this an art show

No crank slow crank for dummies!

My cranking motor grounds through engine block

just replaced a starter in my 2006 Pontiac g6 n now it still doesn't crank mechanic thinks it's the anti theft system. so what to do

I have to vehemently disagree that 80% of the time it's wiring!! Almost ALWAYS it's corrosion and or dirty battery post/terminals....period. And a wee tip for newbs...if you find yourself stranded with no tools & (no, or dead slow crank)...lift the hood, place 2 hands pressure on each positive and negative battery posts, and apply a slight turn in either direction. OFTEN this will re-establish contact with the starter. When you get home, remove those terminal cables...clean them and apply a very small amount of dielectric grease.

Can I go to the bathroom 😆

Have you ever considered illustrating children's books?

Video could have started at 2:55 and saved tine

I spaced out. Can I borrow somebodies notes?

Dan, are you still around????

Less art more explaining.

Thanks SO much for wasting 5:52 of my life. That was as much of the stupidity as I coulds stand. Thanks for clarifying the ACTUAL name of the spinny thingy that spins the thingy that makes vroom vroom. Now I will sound like an actual mechanic when I got to the parts store to get a new canker....or cranker solenoid. Oh and by the way.....it's a cranker solenoid RELAY...technically speaking.
