One wire GM style alternator wiring help needed.
My GM 100 amp alt. was mounted using the power steering bracket as seen. I had a Pos. bat. bulkhead mounted to the frame rail and connected to the directly to the Alt. with that large black wire pictured. I kept throwing the belt at 8500 RPMs. so I put normally closed relay between the Alt and the bulk head to shut the alt off before doing my burnout. Just the opposite of a starter relay . If you shut the alt. off there is no resistance on the belt from the alt. works great.
