CHARGING SYSTEM

2002 Cadillac Escalade Ext

Electrical problem
2002 Cadillac Escalade Ext V8 All Wheel Drive Automatic 145000 miles

. When I first start my truck, the battery light comes on and the voltage gauge shows 8 or 9 volts. After driving for a few minutes, it goes up to normal 14+ volts and the light goes off. Problem does not surface again while driving, only when it is started again. Suggestions?

Lol a bigger hammer would be cheaper, but it sounds like you need a new alt. Bad connections can either make contact when warm/hot or lose contact, depending on the situation. That is how you used to check ECM's back in the day, slap them with your hand, if the car reacted it needed a new one

My pleasure.I do suggest that you use an OEM replacement (A/C Delco). Cheaper is exactly that. Cheaper
