I just got an '86 Honey RV that's got a 454 in it and am trying to decipher all of the wiring. There's a lot of junk in the front of the RV, some of which needs to be replaced and some of which can probably be removed.
Here is something that was wrapped in tape and comes off one of the two batteries in the front bay. The two batteries are separated by isolators but can be bridged together in parallel using an "emergency start" button next to the steering wheel for an extra boost of power.
It looks to me like this is maybe a thermal switch or fuse? You can see a contactor on the bottom right of the picture. Whoever did this was clearly making it so the contactors were always connected. I can't find any good comparison pictures using google images, searching for "thermal switch" so maybe that's not what it is. Does anyone have any idea? I'd like to know if I should find a replacement for whatever this is for or of I can simply switch it out for a single wire.
