So bad mistake, can't blame it on my help but we reversed the jumper cables positive/negative and now nothing works except for the trim. It's a 1996 volvo penta #50FL PNCA. I replace the solenoid with no help, I used a screwdriver and crossed the lugs and it will turn over. the two 50A red breakers don't move so I'm not sure if one of those are bad, is there another master fuse? Any help would be much appreciated!
