What should my Volt. Gauge be reading at??

I just replaced my alt. and i was wondering what the volt gauge should be reading at idle, and lets say 2k rpm.

thanx

this range should be fine

running - about 13.5-15 volts
not running - 12.5-14 volts

depends on what kind of draw you have too, electric fan, sound system, etc.

i mean on the gauge itself..it the dash. i dont have any volt testers at my house, and i have a cd player and a small amp and thats the only real draw i can think of. and i think a different fuel pump that might take more juice.

the stock gauge is too inaccurate to determine anything, IMHO.

Kdog, how do you get over ~12.6 volts on a battery alone (car off)? are you running a 16 volt battery and did not tell us.
