Can anyone help determine what would be the correct voltage regulator for a 1960 Super 90? I thought ours was lost to time, but I have uncovered a couple in a box. I think the photo of the one below could be original, but I have no idea how to tell.
Your 1960 Super 90 would have the black Bosch voltage regulator. On the side of the base should be numbers that give the voltage rating and an "R" which designates 1960 and a number 1 through 12 for the month. Considering the degree of "patina" on the regulator, you'll have to wire brush the base to see the numbers.
Joe Leoni used to calibrate and restore the regulators. I don't know of anyone who currently does. Hopefully, someone with that info will weigh in. I'd remove the cover and check the mechanisms (contacts). Maybe in better shape than the exterior.
Thanks for the replies. This one has RS/UA 160/6/24. Der Whites seems to suggest that is from a Carrera. We unfortunately don’t have a Carrera. Any chance the Super 90 shares regulators with Carrera?

That’s not correct re Carrera only
It was used on S90’s too. DerWhites is a confusing layout but it shows that regulator with several other engines including some of the S90’s. They specify which engine range of S90’s it was appropriate for.

Hi Richard. Thanks for kicking that back to me. I saw the spreadsheet up top, but not the table near the bottom.
What is interesting is it lists RS/UA 160/6/24 applies on Super 90 "To Engine # P-800.148". Our engine number is 800698, which appears to be outside the window.
I realize there are exceptions to the 356 rules. It seems like too much a coincidence that we have this regulator. I guess someone could have swapped it out somewhere along the line...

Dennis: did you find the date code?
I've been over it a couple times with a bright LED light. I'm not seeing what I understand to be a Bosch date code marking. For example 4R would be April 1960. I will give it another look tonight. Maybe I'm not looking in the right place. I'm looking on the silver color base that mounts to the firewall.

OK. I think I found it. The date code does not appear to be as aggressively stamped into the metal, and thus harder to read. I find "3N" Which translates to March 1957. That seems pretty old to be put on a 1960 car at the factory. It is still in the DerWhites usage range.

P.S. These images are rotated on my computer. When I attach them to a forum post, the rotation is lost.

That's the date code. It does seem older than it should be. Have you removed the cover to see what condition the components are in? I'd opt for a 200 amp regulator. I'm sure one can be located and maybe one closer to the year of your car.
