Alternator Gauge Volt Reading...
I have two questions -
I just replaced the alternator (140 amp) in my 1999 SE.
1. What should the volt gauge read/range?
2. It is normal for the gauge to slightly move in-synch with (using) the turn signals?
Thanks!

How old is your battery? At idle the alternator does not charge the battery so you are running off only the battery, I would think if the battery is old then that might happen but with a good battery and not too much draw from the battery I wouldn't expect to see a fluxuation
