Thanks Sid....I found out it was the new alternater that was just installed. I returned it and got another one.....and...WHAL-LA!!!! now its the perfect volts.....13.4 to 13.8

Mitch, my suggestion is to first check the voltage (engine running of
course) with a digital voltmeter. I would make the measurement at (or as
close as practical) to the battery.
