battery disconnect

AS many times you have to disconnect the battery when working on the jeep one of these seems useful. Are they dependable? Any downsides?

As long as it can't vibrate loose it should be fine. I've always run one like this in my YJ and Willys. Meant to be a dual battery switch, but I use it backwards and put the truck on 1 and the winch on 2, that way I can disconnect the winch from power most of the time or in an emergency if a solenoid fails closed.

In my opinion, you'll just be adding something that can go wrong.

I had one installed in all 7 of my Triumphs and i have on one in my ZJ now. If installed correctly, i.e. tight, they are great.

Make sure your connections are tight and clean and you should have no problem.

Looks like that particular one coralman is a little cheaper on Amazon for $16.25 but can't see the shipping since I'm a prime member. May want to read the reviews since some aren't very good.

Know what you mean it's kind of a pain to disconnect the battery every time you disconnect anything electrical like a sensor. I've thought before about going to a brass marine type connector on the neg post with a wing-nut on the top like these below.

http://www.cloudelectric.com/product-p/bt-00639.htm

Have a hard time believing these are really pure brass with the low cost for a pair. Maybe they are but they hit you hard with high shipping/handling costs?

I always thought the square military-style connectors may be better but don't know if the sell one with a wing-nut for a tightening nut? Removing the cables would be easier but don't know if you could turn the wing-nut with it being that close to the top of the battery case?

Personally, I'm a big fan of marine terminals. It's just as easy to disconnect, and it makes it easy to add +12v lines for whatever you want.

marine terminals aren't generally up to the task for offroad vehicles and accessories. don't even think about adding something like a winch to them. they've been known to melt under load.

same with the screw in/auxiliary terminals on actual marine batteries, not recommended for that kind of use.

OP has a stock 2wd I6. It was just a suggestion. They've fit my needs well over the years. The most I ever had hooked up was two foglights, a Harbor Freight power inverter, and a amplifier. I don't think he needs to be paranoid about his melting and setting his Jeep on fire.

But I agree, for any kind of serious draw the marine terminals would be the weakest link.

The whole thing was I just replaced the harness about a year ago{mega bucks mopar} and the negative terminal is getting weak from the off on cycle. I was just looking for a way I could leave it alone and just disconnect by some other means. Some of them are plated brass which I wont use, but the moroso one was a dull color so I was thinking it might be at least closer to a base metal. I really didn't want to hack off the negative clamp to use something else, since I don't trust a crimp on terminal unless it had been crimped and filled with solder{pellets or silver soldered}.

After reading the reviews Uni pointed out they are not so good in all situations. The Flaming river brand does look pretty tough and is similar to what Old Jeep was talking about. Problem is I think I'd have to construct some kind of mounting isolation point... more thought is needed and right now that would make my beer get hot,lol.

While searching around for info coralman I ran into this article where wing-nuts for marine battery connectors are a thing of the past and loose connections cause damage to modern outboard motors/computers.

http://outboard-parts.com/battery-te...you-big-money/

Didn't like reading that since ZJ's have enough electrical problems. Even if I had some type of wing-nut type of battery connector I'd probably still be tightening it with a wrench or channel locks.

Just a thought... Since you just want to kill power, why not just shut down the PDC with a switch at the input feed?

Here's one style that would work with a bracket. There may be some other style that would be more suitable.

I was looking at that very switch at HF today Zee. I'll have to study the area around the PDC and see if I can come up with a mount. Went for a set of metric flex head stubby wrenches but they had sold the last set. Going to HF has become yet another monthly trek but its an enjoyable one.

Grainger has a large selection of kill switches. They are a little pricey though. Consider using a bus bar from the stud on PDC to connect to the stud on the switch. This would mount it and connect it all in one, plus eliminate the need for additional wiring.
