The first thing I did was to clean up the fuseblock and put di-electric grease on the fuses. I also did the same with the relays,about 5-6 of them. I was an Commercial Electrician,but this stuff is much different than I'm used to with the computer controlled motor. My other vehicles don't have them. I've been working on motorcycles and cars,tractors,etc for about 50 years and haven't failed to get one fixed. I guess I'll sell it for junk.
