Voltage output from alternator

i believe 14-14.2 is adequate...im not a mechanic.

2,000 RPM's 13.8v - 14v is fine .    Battery with engine off 12.8v

Idaho..........Your good......Plus what Alan says...............Bruce

Honestly I'd worry if it were much above 14.2. Been there, done that.

@Idaho  Good thing you checked in here - Your guy is a Putz.

I'm good with 13.8 - 14.2 as well.

Much above 14.2 will overcharge your battery and cause it to (a.) heat up un-necessarily and (b.) shorten it's life (along with some of the incandescent bulbs in the car).

If your alternator was undercharging, then your alternator light in the Tach would be lit.  No Alt light when running? - Things are charging just fine.

Much above 14.2 and you will start smelling hydrogen-sulfide (rotten eggs) from the overcharge.

Thank you gentlemen.  Alt light was coming on very dim, then sometimes getting brighter when rpms went up, an intemittent problem sometimes. It seemed related to he headlights/fog lights, too.  A post a year or so ago addressed the issue (sounded the same) and the owner addressed it by cleaning and the grounds for the negative battery cable: one to the top of the steering box, other to the top of of the beam in front of the gas tank.  He said it seemed to be a fix, and would report if it was, but didn't check in again.  Then it just stopped, but the ignition switch went goofy and wouldn't return to the run position after turning it to start.  Had to manually turn back.  So...I'm attacking the ignition switch first, the grounds at the same time, and then, if necessary, the alternator.  Hate electrical issues.  Idaho

If you have an AGM battery, there isn't any smell.

I believe it's more like over 15 volts though for problems. I've seen batteries charging at 14.5 to 14.8 volts if they were very low on charge with no problems.
