1989 Chevy Truck V8 Four Wheel Drive Automatic
low volts on volt gauge. Alt has been checked and is putting out almost 15 volt when being tested. When in truck it shows 12 volt.I have 12.38 volts going in and that should be enough to turn on voltage regulator. The brown wire on alt harness has no volts showing, according to Chiltons the brown wire goes to my inst clust, gauge in the truck shows only 12volts. The test to check for short came up no short(test light on pos cable and touch to pos side of battery, test light doesn't turn on). What am I overlooking and where do I go now?
