Hi everyone, having an issue with the charging system. Had the alternator checked all good. Cleaned the contacts on the regulator but still not charging. Anyone know the part # for the regulator. Thank you

I assume you're sure the system is not charging, and that its not the dash gauge wiring that has an issue. Did you open the regulator box to see whether there is anything obviously wrong inside it?

Does your voltage regulator have 3 terminals, or 4, or ?

NAPA doesn't list a regulator for a 1966 Avanti, but they do list one (row of 3 terminals) for a 1964 Avanti:

   ....Or does your old regulator look like this instead:

I don't know for certain what Avanti Motors used in 1966, but if you have a row of 4 terminals on your regulator I'd guess one of these would work

The voltage regulator for your car is a Delco-Remy part #1119507.  That's an old number and GM has completely changed their parts numbering system since then but if you can find an interchange from old to new you can find a current replacement part.

Looks like the Napa # is MPE VR142SB and the O'reilly number is 2VR4 MFG -MPI  I matched it up to a 1968 Firebird. I will go when they open and match it up.
