I put an Excessive Amperage 350 amp alternator in my Tahoe and it charges perfectly fine but my battery light will come on and go off and it will say it's not charging.
I noticed the plug has three wires on it and the connector on the alternator has three prongs but the three wires are from 1 to 3 out of 4 and the connector prongs are 2 to 4 so only 2 wires are being plugged in.
