[MR2] 85 alt pegged

[Bob Schultz]

I took a Lexus alternator to AutoZone and their cool digital tester said the
unit was good, we tested it twice.

Not believing them... I stopped by Advance and used their old style analog
tester and the Alternator failed...

A new unit solved my problem and I have no idea why the digital unit said it
was good.

I'd take to AutoZone of such and have them throw a tester on first.

  Hi guys.  Driving my 85 mk1 last night on a short run (thankfully), all
the warning lights went on as the alt briefly pegged the meter at about 22V,
then returned to normal.  Did it once more before I got home.  Bad internal
regulator I guess?  Replaceable or rebuild at an electric shop needed?  Too
bad they don't plug in on the outside like many older Bosch.  Much simpler -
more reliable too in my experience.  TIA, Ron.
