Lol I'll paint that (Red) ground wire black so more people won't get triggered. Didn't feel like buying a new roll of black wire for a small section.

its not about being triggered. its about safety. these conventions exist for a reason. you or someone else could easily mix them up and cause a short, a fire or destroy your electronics

Is this a German car? On a lot of old German cars, the positive wire has a black coat and the negative has a reddish-brown coat.

@@carsandstuffchannel1252 spiral black electrical tape around it at least..

@@carsandstuffchannel1252 people here are stupid always check before messing with the terminals or trying to jump start duh how lazy are these people

Horribly loose!

look not so tight maybe

Hard to find these in stores now. Get on line all the time sucks

Yup .... 100 Miles driving to find one ...😂

I have the same problem, so u had to problem with battery drainage after this.

@@JAlves88 no, i fixed the problem with this device!

....The Mistake stims from Two factors .....Being Color Blind OR.... A Failure to Read Directions! NEVER EVER PUT A BATTERY CUT OFF SWITCH ON A .....POSITIVE BATTERY TERMINAL !!

The ONLY reason I'm interested in one is to STOP a "parasite drain" on my tractor. And the only reason I'd prefer a kill switch in preference to pulling the terminal off, is I've done that so many times the wiring into the terminal is damaged (I'll have to solder the terminal onto the wire).

@@OhSoddit I'd suggest a knife blade type of kill switch

@@OhSodditme to .. what did you do ? I’m looking to get a kill switch also

I thought you said it goes on negative terminal. Maybe I’m missing something but the red wire going to the device installed usually means you installed it on the positive leg of the circuit.

God, thanks man. I was scrolling through the comments to find this answer

Can this be hooked up to the positive side if it wont fit on my negative side?

@@SteveV74 No, don't connect this to your positive side. Only negative side. You do the positive, and while driving if something touches or interferes with the positive flow, it can burn out your computer boards and other fuses. Turn your engine off, then turn the kill switch.

lol

Me too dude. I was wating for something more dificult

Exactly the situation I have. Theoretically a negative disconnect still works, as even with a "live" positive there's no connection back to the battery for current to flow (you can connect the positive direct to ground - nothing happens because there's no "circuit"). However, this "kill" switch clearly still allows leakage, so it isn't going to work on my tractor! (Easy enough to just pull the terminal off, but I've done it so many times I've damaged the wiring and will have to solder it together).

My car started shorting out a few month's after i started using this. Took it off and everything went back to normal

@@luisbelloso7282 same when i ran one a few years ago and looking into other cheap simple choices

What you are probably seeing is a parasitic drain feeding back through the wire from one of his on-board components. A lawnmower would not have that. Before investing in one, disconnect his negative terminal and use a voltmeter to see if there is a drain on his battery through the wiring harness. Then if there is, you can follow the leak down the wiring harness, disconnecting each component as you go to find out which component is bleeding off current and draining the battery. Very likely it is the magneto, which is probably located under the flywheel.

@@Matthew_Loutner thank you for being smarter than I am. Personally I was lost and couldn't understand it and then when I was reading what you were saying and I started thinking, maybe it's a headlight because it is equipped with two headlights. Then you said there's a magneto under the flywheel, I didn't have a stinking clue of that. It was definitely be on my pay grade. Could that magneto be the reason that it backfires when turning it off? I understand if you don't know but because I can tell you're smarter than I am, I have to ask.

@@DonaldAJr Backfiring when you shut it off is called afterfire. It is unburnt fuel igniting inside the muffler and exploding. It can be due to number of causes from carburetor adjustment to running too hot to a fouled sparkplug not burning all of the gas. Try letting it idle for 30 to 60 seconds before turning it off and see if it still does it.

"the disconnect itself is less than perfect and is still allowing a slight connection" this

The threads of the knob are still in contact with the terminal lug. You should completely separate the two pieces for a total disconnect. It's not hard to re-screw it since it's a big green thumb screw and don't need any tools.

butnut Mikami why not just disconnect the negative cable instead of buying this?

its a QUICK disconnect and you dont need a tool box and a couple of minutes time to disconnect..

FuzzballToday yes but it doesn’t do 100% disconnect. As far as tools it just takes a battery wrench. Walmart $4.00. I put mine on a keychain and hang it on the turn signal. But I understand with this you don’t need the wrench.

The safety protocol in mechanics is that you always connect the negative terminal last and you always disconnect the negative terminal first. Following that procedure ensures that you do not accidentally short a hot wire against the car body or frame and make some sparks.

It goes to the stereo amp.

Why not just use chassis ground?

Yes this switch gave me big problems after a few month's. I do not recommend at all

@@luisbelloso7282 I just ordered a side post isolator and my battery is in the trunk (2003 Saturn Ion). I believe I have a parasitic draw, but I cannot even figure out how to find it. So, I figure if I shut down the battery it will not draw the battery down overnight.

Without a complete circuit it's not possible for something to be draining the battery. It's much more likely the battery is bad. Even a new battery could have a defect. There's one possibility. A low power circuit may be being created if when the hood is closed somehow it is touching both terminals. Look for marks on your hood. You can also buy a piece of rubber and glue it to the underside of the hood above the battery.

Fordman Truck concurre with your statement, buying from Walmart is like buying from the cheap China men...

The plastic separating the top and bottom metal is very thin and if the plastic is not glued to the metal parts the whole assembly is loose and prone to still short even when you unscrew it. The one I have wasn't glued together and was loose, so I used expoxy resin glue between the plastic and the metal parts to make a firm bond so when you unscrew it, the whole unit remains tort. Tested with multimeter and it shows 0.000 continuity

Just remove the green knob and lift the cable off completely. No tools required and definitely disconnected

Bella C just take the negative side off of the battery. They sell those little battery terminal wrenches at Walmart in the battery section. That’s what I do on my van camper. The problem is everyone wants everything too convenient nowadays. It is called laziness.

@@normanleger247 but with the + still connected will it not continue to drain?

@tiny desk yeh sometimes it’s the drizzling shits too.

Can you connect a loose battery to your trickle charger?

I keep an unregulated 500 Mah 24V battery charger on my solar battery bank of 16 deep cycle100AH batteries. Lead acid batteries like a little ripple in the DC to keep the sulfation off the plates. I also keep my batteries (no matter what the use) CLEAN to keep conductive dust off the tops of the batteries causing a high impedance short from forming and slowly draining the battery over time.

He said 'secundary' anti theft

You just tighten it down more or use terminal shims

20 would be the correct setting.

Agreed.

Usually yes, though, there tends to be devices that you can plug into the cigarette lighter socket that provides just enough power to keep things from losing memory, but makes it safe to work on the vehicle. Still a bad idea to use those if you know something will be shorted for awhile under the hood.

I'm only putting this thing on because my battery drains to dead after every jump. All those things are lost when the car dies.

Lars Dahl you are right, but for some uses it does not matter. I am going to put one on my travel trailer.

I started getting shorts aftet using this for a few months. Took it off and everything worked like normal again

...Green for green car. ...red for Red car ..and so on.... Now You know!

You can use them for 72 volts. What you have to check is the amperage rating on the box. Mine is rated for 125 amp continuous and 500 amp surge. The surge is for when you are applying the starter.

I don't think he's alive anymore

No it is not recommended.

NO!

No. Never connect to the positive side.

one item he didnt mention...actually two.. one.. the directions on the same iten at walmart says.. TO ONLY CONNECT TO NEGATIVE SIDE OF BATTERY... which is what he did. 2) the green wheel can be removed completely for additional security. honestly.. im only interested in this product (or ones like it). so that my interior lights will go out (seat belt warning/s). this will help until i figure it out. if you notice, he gave no reason for installing this item. anti theft or not.

Paint lol but they in black too

........ very good point, people might mistake the negative for positive when jumping the car.... Thanks..

to make it look positive? which its not.

Sure, if you want to confuse yourself, and connect the jumper cables backwards and ruin the computer components of your car. Don't change anything, use the shutoff on the NEGATIVE pole of the battery - never, ever on the positive pole.

Better than no done haha

@@carsandstuffchannel1252 would this work if I hooked up a heavy jumper cables, to battery and put the switch in car, and run off the other side, back to the cars ground, to use as a battery kill switch cause something is draining the battery, and such a hasle having to open hood every time to connect battery terminal?

you should only install it on the negative side plus it only fits the neg side since the terminals are different sizes.

+Cars and Stuff Channel Thank you 🙏🏽

+Cars and Stuff Channel Thanks for this simple and informative video. Going to order this from Amazon right now. I'm leaving my car at the airport parking lot for almost three weeks. I have a 2006 Acura tl with all the unnecessary bells and whistles and my year old battery drains if car sits too long. Hope it starts when I get back.

S Hall did it start? I just ordered one.

123 456 He put it on ground. The cable is a repurposed pos cable.

They work fine for me

thanks for reccomending your alternative.

This part is not "junk" as I have used them for years on my '90 Ford Ranger, and my '79 GMC C-1500 with absolutely no problems. I'm afraid that you have not bought the American Exide made part, but rather a cheap Chinese copy.

longshorts3 yes and it’s probably made in China too. I bought a little terminal wrench at Walmart and I just take the cable off of the negative side. 100% disconnect that way.
