Yes, that's the way I have it wired. At the VR connector, the brown wire is jumpered to the black/white tracer wire and that's going to the L terminal on the alternator. I've check and checked and double-checked that. It was all working fine prior to replacing the previous alternator with one just like it.
I've studied and looked and studied on every wiring diagram I have, used them to map out just the indicator light circuit on paper so I can isolate it. Every time I think I've devised some sort of test to isolate what's going on, I turn out to be wrong.
Here's my latest attempt - but I'm so cross-eyed right now from trying to follow lines on paper, who knows if it's right?
One side of the indicator bulb connects to pin 8 on the cluster connector, to a fuse in the fuse block, and back to the "run" terminal on the ignition switch. Also at pin 8 on the cluster connector is a wire that goes eventually to both one side of the downshift switch and the idle solenoid. The other side of the bulb connects to pin 12 of the cluster connector, to a terminal on the firewall connector (BZ on the wiring diagram), and on to the ACC terminal on the ignition switch. Coming off that same BZ terminal on the firewall connector is the path that winds up at the "L" terminal on the alternator.
I've been staring at the circuit diagram and still can't seem to understand how it's supposed to ever work. Looks to me like there's power going to both sides of the bulb all the time, with one of those legs also running off to the alternator. Either I'm still missing something or I just don't understand...
I did just notice however that with the ignition on, engine off, the alternator is making a high-pitched hum. Wonder if the doggone thing is bad?
