causes for high volt meter reading +16 !

Installed a 1994 LT-1 from a Z/28 in my coupe. Upon startup the volt meter pegged at 16 + volts ! What are the causes for this ?
The car has a new Optima battery
New Shark in dash volt meter gauge ( made by Dolphin )
The starter and Alt. were taken to Advanced Auto and checked out O.K
The wiring is a new Ron Francis setup for the LT-1
Besides, the high volt meter reading the stock dual electric fans work intermitely. This may,or may not be the cause for the high volt meter reading ? Any and all help would greatly be appreciated
Thanks

Do you have a multi-meter? If so check the voltage at the battery terminals while it's running...if it matches your gauge the voltage regulator is probably bad

Are we talking a true VOLT meter or a Ampmeter?

theres 2 diffrent ways of wiring each.

An Ampmeter wires from the positive on the bat to the positive on the alt.



And a VOLT meter wires + and -

high volt meter reading

Thanks, for the suggestions.
I will check the voltage readings at the battery.
I have a in dash volt meter..not a amp gauge.
I will double check the volt meter wiring also.
