Default Re: Alternator Trouble

Yep! You have it correct. Your alternator is bad. Assuming there are no bad connections. Your battery starts the truck, and handles any surge draws for power, but once running, the alternator is the power scource for spark and everything else. Your alternator should be putting out 14 volts when working properly.

DO NOT go off driving anywhere, because it will run until the battery gets to low to provide enough power for spark and then the motor will shut off. Swap that alternator out and you should be good to go. Alternator are a really easy item to replace if you're even slightly handy with simple tools. Just make sure you note what wires hook to where.
