I'm not sure but to my long memory Alternators have had solidstate
regulators and no relays since they were invented. :-Z

You're definitely wrong about that. Atlternators made their first
showing in large numbers maybe in 1965 or about then and all of them had
relay-based regulators, with two of them, for several years. Then some
had relay-less regulators within the alternators, but they made cars
with both styles for a while.

I guess I was forgetting sold-state regulators and assuming no matter
what year his car is, he had relays. My mistake. (I don't know if
they ever made external soldi-state regulators.)

Chrysler Corp. vehicles had a transistorized voltage regulator on the firewall. They were pretty reliable. Here's a link to eBay that shows both mechanical and solid state regulators for older Mopar vehicles. My 89 Dodge pickup had the voltage regulator built into the engine control computer. ^_^
