when I set ignition switch to ALT to run the radio etc. the alternator light comes on (dim)
everything seems to work .
had a new regulator put in last year and the alternator was checked out and it tested fine.
yes i agree when its in the ON position .
but im talking about accesory position.
positions are accesory, off, on, start.
ya know rotate the key towards you to power the radio and other accesories.
with it in the on position yu got juice going to the ignition circuit.
in strart the ignition circuit and starter come into play.
GM did something a bit strange on the first gen electrical systems. The IGN and ACC circuits are shorted together with a resistance wire. I think this was to keep the charging system operational if the GEN bulb burned out. But this is why the light illuminates dimly in the ACC position. The resistance wire is brown with a white stripe. It is connected to ignition switch and fuse block (if I recall). The wire is about 4 feet long and taped to the harness, so it runs down the harness, doubles back and reconnects. Very strange.
