One of the wires in the harness between the alternator and the voltage
regulator is a sense wire. If it does not make good contact the voltage
regulator
will tell the alternator to run wide open. Make sure all the plug connections
are clean and none of the wires are broken. You will burn out light bulbs
and cook the battery in short order. I had one like this and it turned out to
be a crusty connector.

New problem on my '69 2000. I have a problem that first appeared 2
weeks ago and I haven't figured out yet. Seems like the alternator is
full on all the time when engine revs are sufficient to generate
enough current. I measure up to 17 volts going to the battery. I
tried a new regulator and no change. With the engine off after a 1/2
hr run at this high charging voltage, the battery reads 13.15 volts
(read on the battery terminals and also on the console cigarette
lighter socket). I'm suspecting wiring problems to the alternator but
haven't had time yet to probe around. Anyone else out there had a
similar problem they solved? I figure I'll go over it this weekend.
Ammeter reads +30 Amps when the engine is running above 1.5K RPM so
the battery is sinking a lot of current at this high voltage. I don't
want it to boil so I limit engine ON time until I can get it sorted
out.
thanks for any help
