Can I check the alternator by jumping the truck off then unhooking the battery, if the truck goes dead, the alternator is bad? THarms 10-06-2006, 04:22 PM My sons T-100 battery was dead this morning.

You should have the battery checked first... just because its only 2 years old doesn't mean it is still good. Check the easy things first, then work your way to the more difficult. | |
