I guess I would start looking for any wiring that does not appear to be stock. Look around the fusible links, and the coils first.

Download the 79 FSM from rotaryrefs.net and start studying the wiring diagrams. From you're description, repair will take an onsite visual inspection and comparison with the oem wiring to sort out your problem.

Mine did this when I tried to convert it to internal VR alt, so check the VR itself.
Also to upgrade to the 81-85 alt would be a good idea if you can fing the write to convert the SA's to FB's alts.
