I'm getting ready to rebuild a 66 overlander, but before I tear it completely apart, I want to see which systems are working and which need help. The 110 system is fine, and I only found one problem on the 12 volt
system, is in the pic. The blue wire coming from the trailer connector (for the tow vehicle to charge the trailer battery) goes into what looks like a breaker or switch. It is in an access panel toward the front of the trailer, so I assume it is a common item. I know it needs replaced, but I'm not sure where to look or what it is called for sure.
I also found no problems at all with the uni-volt system. I saw several posts here in the forum where the univolt system was replaced or upgraded. Is there a problem with this system I should know about, or if it's not broke, don't fix it? Thanks, Tom
