my 1988 suburban is not charging. i want to make sure the wiring around the alternator is working prior to stuffing a new alternator in and burning it up.
the volt gauge on the dash works and reads battery voltage but does not show charging. using a meter across the battery and from the output on the alternator shows the same. i do not believe there is a dummy light in addition.
the 2 wire clip that goes into the alternator has a brown and a faded reddish wire. the brown wire goes to L "lamp" and the reddish wire to F "field"
on some of the other GM products i have the L lead shows power when the key is on but the engine is not running. that is because it is in the dummy light circut.
on the suburban the L wire does not have power when the key is on. rather the F wire has power. is this correct? only questioning because i stated my other GM products have power @ the L wire...
