I recently purchased a 1992 F-350 with the 7.3 IDI. V-Belt style, external voltage regulator.
My alternator light came on and lo and behold, I wasn't getting any output from the alternator. I put in a new one as well as a new pair of batteries. However, the new alternator is still not charging anything. I have tried two different ones from the parts store.
I will be honest, I'm a GM guy and don't fully understand the wiring on these trucks. However, I tested for continuity between the positive post on the alternator and the battery and there was no continuity. There is continuity between the ground post on the alternator and the battery.
Where should I start looking to resolve this issue? Could it be a bad voltage regulator? Are there fusible links in the wiring, and if so, where/which wires are they connected to?
