Take it to any WalMart or Autozone for a free test.

RE: over charging

yah voltage regulator's have been internal for a long time now

i would say your alternator is on its way out, normal is about 14.8 or so

go get it tested

Glad I can help,
Yes Wiz
Regulators have been internal for a long time, even good old FORDS are internal.

What if his meter is just out of calibration. I know, I repaired meters for many years.

That is why I suggested to go to a Wal-Mart before he spends $300 for an alternator.

RE: over charging

Thanks, I changed out the alternator. All works fine now. What was happening
was once the alternator got hot(engine up to temp.) it would peg out to 18 volts.
did not want to fry all the electronics.
