Per the dummy gauges, the truck has been charging at the "L" of normal and the other day it was above that. So I put my voltage meter on it while sitting in the driveway, nothing on, and it is charging at 15 volts +/- (hard to tell with my meter). This can't be good for the system. Any way to adjust the regulator? If not, what could be the cause?
Re: System Charging at 15 volts + - can i adjust it?
Thats about where my dumby gauge is too, sorry can't help you.

Actually depending on system conditions you may be ok. Example a weak or a dead cell or two in a battery will make for a higher charge rate. As well as temp, engine rpm etc. I would check the bat's.

How accurate is your meter is the question I would be asking... Over time all meter will get out of calibration and your not that much higher than I have seen on The Enterprise or other trucks.

14-15 volts is ok. It takes a higher voltage than the nominal 12 volts to get the batteries to charge.

Yup, Jim's right. The old gasser's voltmeter runs at 14-15 volts all day long. If it drops down to 12 or less, then I know I'm not charging and there is a problem. The factory "gauge" (and I use that term loosely) gives no useful info. Scrap it and install a voltmeter. That's what I'm doing on my project truck.
