I've tried everything I can think of and need some other ideas.
Issue: '79 Bronco with a 400 and C6. Son has been driving and just wouldn't start the other day after school. I tried to jump start and it threw sparks from the alternator.
Alternator and voltage regulator were replaced and still no start. So far I have replaced battery, starter solenoid, and starter. As long as there is no load (i.e not connected to new starter) everything operates and functions as it should. Once the starter is connected, the entire electrical system goes out. I've removed the starter and tested on the bench and it checks out fine.
Any suggestions would be very welcome.
