VREG problem?

My 1960, that is almost all original has an Omix-Ada voltage regulator.

The darned thing indicates charge while at rpm, but after sitting, it just wont start, i.e. no charge in battery.

I have diagnosed this thing to death, and cannot find anywhere a drain is occuring when powered off.

If the VREG is just bad, then I am hesitant in replacing it at 60+ bucks, and just ditching the Generator and Voltage regulator and just going with a Delco 10-si alternator.

Any thoughts?

Don't know how you are testing for drain when all is turned off but the usual way is remove one of the battery cables and connect a test light between the cable you removed and the battery terminal. If your test light glows you have a drain. If not then suspect dead or bad cell in battery is killing itself.

 

My prime suspect would be the battery.
First thing , I'd haul it in for questioning.(load test)

 

Safety note: Always have googles or a full face shield when load testing batteries.
Years ago I tested one for a customer with a bad/shorted cell and blew the indicator out. Have seen them blow up worse.
Take care.
