in the mean time, remove and clean all your battery cables, and retighten them (skipping this and saying they are fine without actually doing it is only lying to yourself...)
also check closely, the 2 blade inline connection coming from the generator up to the harness, over near the battery box and main harness there....make SURE that isn't doing a Meltdown....happens more than you imagine, and when it does go south you are outta commision....till you re do them.
