I just finished replacing the brushes on my alternator since I was having troubles with my truck not starting. I even followed the write up on the maitenance section of this site to replace them. I got everything put back together, put in a new battery (just to rule it out as the problem) and it still wont start. I jumped it w/my other truck and it started fine but once I remove the jumper cables the truck runs for a few seconds and then dies. The battery and e-brake lights still come on. I'm thinkin the alternator is just blown but I'm not sure. Any help would be appreciated as I am a little frustrated.


It's along shot, but check your fusible link. If it popped, the alternator won't charge.

Failing that, have your alternator bench tested. That way you can rule it in or rule it out as the cause. If something's wrong, it's easy to fix. Every part in there is replacable.
