While trying to diagnose a Gen 1 light flickering I ran into this:
With the engine running, I pulled the red/brown pigtail on driver side alt. gen 2 light came on.
With engine running, pigtail back on gen 1, I pulled pigtail on gen 2 and neither light comes on.
Does any of that make sense? Where is the gen 2 light electrical current getting sinked to when I pull the driver side alternator pigtail?
I've looked over the diagrams a million times but don't get what is supposed to be happening since the alternators are sort of a black box. Regardless, before I can continue with the gen 1 diagnosis I need to know if the previous owner royaly screwed this wiring up before I can make any accurate assesments of what I'll need to do either with the truck or the alternator.
Edit: Forgot to add that while the gen 1 light was on while driving the horn didn't work. All other electricals did. When the gen 1 light went out, horn worked again. They may be totally seperate issues but who knows when things are intermittent.
Thanks in advance!
