Hey all.. Been a while since I've posted now, but tonight I seem to have found a problem I can't seem to figure out..
I finally got my long term project running this evening, but for some reason it don't want to charge properly..
I have a 3-wire 10si Delco alternator installed.. "Batt" post connected to Ammeter, "white" (small wire on plug) connected to the ignition switch with a light in the line (as I have done many times before) and the larger wire looped back and connected to the "batt" post..
I've done it this way a few times after reading it here long ago, and have had great success.. until tonight. When the key is turned on, the light will come on (as it should) but the alternator will not excite like it should. If I use a jumper and touch the excite terminal, it will kick in and charge like it should.
I can't figure out what I am missing.. I have it wired as I have done a few times.. Used the same light as I have always used.. I know it's hard to diagnose just by reading, but does anyone have a idea as to what I am overlooking? I looked, tried, and tried again to figure this out for a couple hours tonight, and I am stumped.
