transistorized 10DN voltage regulator

[Keith B.]

where these ever installed at St Louis. Or was this a dealer item. the 65 Corvette supplement shop manual shows them in the charging section.

1965 Corvette with K-66 and C-60 used this style external transistorized voltage regulator. As far as I know, it was the only Corvette application that ever originally used an external transistorized voltage regulator.

Joe thanks was there any other GM car or truck application?

Re: transistorized 10DN voltage regulator

Joe, I'm confused. I don't think that's a 1116378, listed in a P&A Catalog for 1965 Model Y(Corvette) " W/T Ign, A.C. Exc 62 Amp)"

The 1116378 uses the same flat terminal plug as a 1119515. e.g. here
s-l1600.jpg

But I don't see that part # anywhere in the 1965 AIM. Was it ever shipped from the factory? Or was it a Service part only as a upgrade to the stock part# 1119515?

Keith's image uses a round plug so I think that's a Pass car or Truck application only. I can't find any reference part#.

Edit... It may be a 9000590 for trucks. Eg. here

No, the regulator pictured by Keith is not a GM #1116378. You will note in my response that I said it was the style regulator used for 1965 Corvette with K-66 and C-60 although I probably should have been more clear. I thought the thrust of the question was whether an external, transistorized voltage regulator ever originally installed on a Corvette. As far as I know, it was. The regulator pictured in Keith's post is a regulator that was supplied as part of a GM #1985902 conversion kit. As far as I know, this kit was designed to be used with any GM vehicle originally equipped with an electromechanical voltage regulator. The kit included the regulator, connectors, wiring, and a relay. I do not know if the regulator supplied with the kit was available separately or if it was used in PRODUCTION for any application. Certainly, though, it was not used in PRODUCTION for any Corvette application.

According to GM, the GM #1116378 regulator was also used on 1965 full size Chevrolet passenger cars with K-66 and C-60. It was also used on some Buick, Oldsmobile and Pontiac cars but I do not know the years and models. Most likely full size passenger cars with K-66 and C-60. It MAY have been used for 1966 Corvettes with L-79, K-66 and C-60.

Curiously, this style voltage regulator was also used on some light aircraft of the day.

Re: transistorized 10DN voltage regulator

My picture was just for attention, I had no clue there was more than one style. For any passenger car equipped with both K66 and C60 would be one very rare car.

Re: transistorized 10DN voltage regulator

Joe I see that now. I missed it. Thanks. After I initially posted I found one like Keith showed as a 9000590, and showed truck usage, and maybe others. I edited that post.

I am still uncertain why there is no reference in the 1965 AIM for the 1116393, and wonder if it was only available in service.

Keith, agree. A rare combination. My 1965 Pass car data shows these totals.

B Body (Full size)
K66 589
C60 402,565

A Body (Chevelle)
K66 209
C60 42,098

Chevy II
K66 0 (1966 Chevy II/Nova 209)
C60 5534

So if it had both K66 and C60 the totals are likely quite smaller than the K66 number. What may even be more rare is the TI distributor used on those. Maybe Chevelle(if it had a distributor driven tachometer) used the same as Corvette.

Re: transistorized 10DN voltage regulator

Rich the Chevelle and Impala TI distributor is not a tach drive unit.

Keith, If equipped, what drove the tach?

It is electronic and runs of the coil single.

Only Corvette was originally equipped with a mechanical drive tach. All others were electronic.
