70 Control Panel-short?

[rayandre]

We have a 70 Overlander that never had a battery in it when we first bought it. All electrical works fine on shore power and we have all running lights when towing. I put a new battery in, noticed the 40amp fuse was previous blown on the original fuse block in the Univolt, swapped it for the TV 40 amp and tested the interior lights which worked fine. When I went to test the water pump switch it seemed dead as well as the rest of the panel. Has anyone tested a control panel and/or repaired one? The last time I pulled the panel down and looked at the back there seemed to be indications of a short-like a spark. The clock looked a bit fried-almost like a weird surge might have happened. Given the way the rest of this AS was poorly maintained and cobbled together I'm assuming the worst.
