Idk what kindi dumbas* designed that I'm or a lot of things on that truch they make everythin a pita. I turn wrenches all day at work and I still get pis*ed when I work on that thing

 

that fuse works great when you have an intermittent slow draw that would otherwise kill the battery...I have to pull each night or the battery goes dead.....both times I used my meter to try and track it down I found nothing..

 

Have you checked to make sure the glove box light isn't staying on?

 

That happend to me but would only kill my oold junk battery ... I know this is kinda off topic but how do you wire dual batter so it stays only a 12v system? And can the stock alternator handle that?

 

I have never done it, so I can't help, but there are threads on the topic. I know the search function sucks, but try it, and see what comes up.

 

I have not....

 

I've seen the issue on DF more than a couple time's.

 

You run the second battery in parallel with the first. Connect the 2 positive terminals together and ground the negative. Stock alternator will be fine. Or you can use a battery isolator to keep the systems seperate and from draining each other.

 

Soo your say get another battery of the same kind and get an isolator? Where do I aquire one of them?
