never tested an alternator, how you do it?
my battery light came on a half hour ago. i just replaced the battery and alternator at the same time a few weeks ago. i multi-metered the battery and i'm getting 12.65VDC, so the battery should be fine. i tested on the posts and in the cable to make sure it wasn't loosing it from the post to the cable. and the truck starts still, so it's putting out the amps.
i previously had an alt problem and could tell it was bad from volt gauge. at idle it would drop and at higher RPMs it came back up. this time it's dropped down to about 8V and staying there along with the battery light being on. i'm gonna try an reset the computer first and see if that does anything.
