Voltage Regulator Issues???

Hi All,

Yesterday my dad reported that the charging system on his Series 22nd was showing a discharge when he drove it home.

He said that he just thought that the generator was not charging until he got back home and turned off the ignition key he noticed that the ammeter showed "full pegged discharge". He disconnected the positive ground cable to the battery and he heard the voltage regulator click. He connected the battery cable again and the ammeter needle was centered. He started the engine and the ammeter showed a charging as usual.

Does this sound like a common problem? I checked all of the wire connections and they all look fine.

The voltage regulator obviously had been replaced at one (or more) time. A few months back I believe (cant remember for sure) I burnished the contacts while I had the engine out and it has been working fine until yesterday.

The voltage regulator installed in his car has four wires however it does not say AC Delco or Autolite.

Any tips/suggestions while I dive into the service manual?

THANKS (as always)!!!

Bill
