The gauge in my truck has always shown 14 volts, for a few weeks now it has gone down to 13 and up to 15 several times. Does this indicate a problem with the alternator or voltage regulator?
deffinately check with a multi meter.. set in truck and probe cig lighter and do it at idle and revved.
if it drops below 13.8 at idle.. or goes over 15 revved.. time for a checksee.
SG, On a side note. If your ammeter gage jumps from center to charge back and forth, is that a bad regulator? Thanks.
I'm no expert, but a jumping ammeter would probably indicate a loose connection or short of some kind I would think.
