Alternator problems

[alderson95]

Lately iv been having to jump my truck off before I go to work. I have noticed that my volt gauge has been real low like 10 or 9 volts. And it seems that when it getts low like that the truck starts to run like crap. Im just curious if the alternator is going bad if it would cause the truck to run like crap.

First thing that I'd do is make sure that the battery and ground connections are all clean.

I have iv even replaced them. Iv cheched my connections to the alternator and batteries.

Can you put a voltmeter directly on the alternator? If the reading there is low, add a temporary ground and check again, just to be sure. This will help narrow down if the problem is the alt or the wiring.

Ill have to try that tomorrow if the alternater is out I have a life tjme warranty on it so no money out of my pocket

I've had a few of those "lifetime warranties" the taking them back gets old. I prefer an idependent rebuilder myself.

This. I've come to take "lifetime warranty" as an indication of low quality any more.
