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
