I think I've narrowed my no start problem down to the starter. When I remove the starter and hook it up to battery charger on the bench, the solenoid will kick in with a 10 Amp source but the starter doesn't turn. If I kick up the source to 50 Amps, the solenoid kicks in and the starter turns but sluggishly. I've decided this means a new starter because of an internal short in windings.
But before I put out the bucks for the new starter, I'd like to hear if someone disagrees. While troubleshooting I was driven crazy by a situation that I can't explain. If I hook up everything and turn the switch to ON I get the normal oil and charge lights. When I go to start, everything shuts down - no power. If I turn off the switch and turn it back to ON I get nothing - not even the oil and charge lights. I discovered by accident that if I disconnect the battery and reconnect it, everything seems to reset so I get the oil and charge lights again in the ON position. But again if I go to start, everything shuts down.
I can find nothing in the schematic in that circuit that would act as an overload switch that would be reset by disconnection the battery.
