Alternator question Recently replaced a dead alternator in my 2002 Ta. I never paid attention before, but now when I come to a stop, the battery gauge moves a little bit. It never gets below halfway (13) but it will fluctuate back and forth a little bit. Is this normal? I have no electronics other than an aftermarket Kenwood head unit. I do have a cam, if that makes a difference.

Here you go. Most replacement alternators are cheap junk. It's not unheard of to have a new one that isn't working right. The problem is most stores will test it and as long as it puts out 12V, they won't warranty it.

I had bouncing needles while sitting at lights with an old Optima red top battery, after a couple of jump starts I replaced with a yellow top and guages are solid now.

I remember reading years back on the forum about someone swapping to a truck alternator and it working out a lot better than expected. It make be under the Audio section.
