Alternator issues
Our alternator is now reading 12 volts. In the past it always read between 13-14.5 volts. Is 12 volts sufficient for battery charging? If not would this be an alternator fail or a voltage regulator pr...

12 volts is not enough.. However if you changed meters that may be the issue as alternators do not put out DC. they put out rectified 3 phase A/C good chance you've popped a diode or two if you are seeing only 12 volts. An alternator test is often FREE at many shops on a car.. Motor home.. Well may be a big harder to hook up.. Or not. Been a LONG time since I did an alternator test. Pull into "Auto Parts R US" and ask 'em (Generic for most of the low-cost auto parts places) just make sure the store has a big enough lot.
