What did we get into this time?

This 1995 Pace Arrow Coronado motorhome has had a rough winter.
The owner took it to a generator repair shop to get some rodent damage taken care of, and when he picked it up, the truck didn't even make it half a mile from the shop before stalling out!
They also told him that the refrigerator CAUGHT FIRE during the repairs!! OOPS.

The shop shotgunned new batteries at it, but that only made it WORSE!!
Now the generator still doesn't work, but neither does the fridge or hydraulic jacks or the radio.

Join me as we start from scratch with NO WIRING DIAGRAMS and attempt to get this behemoth back in shape.

Enjoy!
