Voltage regulator ?

[BOBS 2 68S]

Alt guage pegged to the charge side today coming home from Arvada. I changed the headlights and the guage cluster light bulb a fews bacK. Nothing else has been changed. Could the regulator be bad?

Did you check what voltage is actually at while charging? Still seeing 13-14v while running?

So I went out to check things out and the battery is down to 11.5 volts and the regulator was warm. I have not driven it since yesterday.

Yikes, something is up then. There are ways to test the regulator but I'm not versed in them. Easy enough to replace though.

I’d confirm the battery is in good condition before chasing volts, get a good baseline charge on it, battery should be showing 13+ volts fully charged, then load test it.

If the regulator failed while running for any amount of time it may have taken the battery with it.

The battery is a concern. I see what looks like battery acid splater on inner fender and hood. It did take a charge and with a new regulator from NAPA , I was able to start and the guage settled to "0" quickly. I drove it about 30 miles with it pegged at full charge.
