Re: Electrical - Voltage Drop

Check the plug on the side of the alt. Start the truck have some one help you, watch the guage and the other person wiggle the wires going in the the regulator on the alt. If that causes the problem then there is a short in the plug or the wires. Seen this same problem on a 99.
