I need some help on the volt gauge

[Nates GTS Viper]

I recently installed a roe blower with a 10# pulley and since then the alt. gauge is between the last number and the line before it. Is this where it is supposed to or is it to high. I just cant remember what it was before the install. Thanks for any help i really apreciate it.

Use a voltmeter at the PDC (jump start location) and confirm the voltage there. Compare to the gauge. Rumor has it the OE gauges are not that accurate so I'd trust a decent digital voltmeter.
