Battery Problem

When my mutt sits for 3-4 days the batteries go dead. New generator working right, new batteries. When I restored my M38A1 I had a similar problem. I found the insulation was breaking down and allowing them to short out. Anyone know if something else might be wrong? Otherwise batteries charge, and hold charge by themselves. 


I had an interesting problem with my A1 a few years back where the batterys would die after about a week of the jeep sitting in the driveway. It turns out that some mice had built a best in the starter switch housing that had some foil gum wrappers in it. The wrappers were putting a resistive load on the batterys that was killing them! I wonder if they also kept the mice warm when they were in the nest?

My solution was to buy a couple of battery quick disconnect couplings rather than install a switch. If someone finds the switch they can start the jeep but without the inter-battery link they're not going anywhere.
Here's what I used on the link: http://14fd9770.linkbucks.com

Something else I thought I'd mention to you Mutt owners. A lot of radio installations were wired directly to the batteries, therefore any shorts in the cable or mounts can drain the batteries. If you leave the radios installed, most of them have a capacitor across the input power line and if it gets leaky it can drain the batteries pretty quickly. The AM-2060s were know for this problem.

ALWAYS CONNTECT A KILL SWITCH ACROSS THE NEGATIVE SIDE OF THE BATTERIES! That way if your wrenching on them and the wrench hits ground you won't light up!
