Notice lack of resistor and indicator light.
OK. I stand corrected, and have RetConned my posts. The tab off #4 on the side of the box is for a Noise Cancelling Condenser.

Lightbulb Re: voltage reg problem

I recently replaced the original 519 VR on my 1970 Blazer with the optional 61A alternator with a new D635 solid state VR. I had a flickering light condition with an occasional voltage spike to 17v. The new one solved all of the issues. I was able to maintain stock appearance with the use of the original embossed Delco Remy Made in USA steel cover.

Same here. I replaced the original over charging VR in my '68 with the D635 solid state VR, idle voltage was near full output. Much better electrics now.
The alternator is all original, nothing changed or replaced in it. 60k miles in 56 years.

Who sells the D635 and what's the price?
