WERE THESE USED ON MID YEAR CORVETTES I HAVE ONE DATED 5 E IT CAME WITH MY CAR IT WAS NOT INSTALLED BUT CAME IN BOX WITH OTHER PARTS I HAVE NEVER SEEN ONE USED ON A CORVETTE ONLY SEEN USED ON A FEW IMPALLAS ....

Re: ELECTRONIC VOLTAGE REGULATORS
Lose the caps, in internet etiquette all caps is considered shouting. Yes, a transistor regulator was used on '65 AC? cars I believe. I do not have the part number in front of me, maybe Joe Lucia will chime in.Dick WhittingtonComment

Re sorry about the capps
i have a bb car the wiring was cut off to the regulator and this one came with it so im wondering if it came on it or its just a part to be soldComment

Re: ELECTRONIC VOLTAGE REGULATORS
Dick and Donald-----
Yes, 1965 Corvettes with L-79 or L-76 with C-60 and K-66 were equipped with a transistorized electronic voltage regulator. I don't know if this unit was fully solid state or just partially solid state, though. The part number was GM #1116368. The same unit was also used on other 1965 Chevrolets with 62 amp alternators.
Supposedly, another transistorized regulator was used for 1966 Corvettes with L-79 and C-60 and K-66. However, I don't know if one of these has ever been found and verified. That regulator was GM #1116378. The GM #1116378 regulator definitely existed, though.
Interestingly, these regulators were also used on some older general aviation light aircraft. I've seen them on a Navion and a few others but I don't think they were originally installed. I think they were likely part of some STO'd modification.In Appreciation of John HinckleyComment

GM #9000590 was a transistorized voltage regulator. However, I can find no information that it was ever used or cataloged for use on a Corvette. I don't know what the specific application was, though. However, it was used on Chevrolet, Buicks, and Pontiacs.In Appreciation of John HinckleyComment

thanks for the info.....
i appreciate all the help thanks donComment

These may have been used on school buses
I have one, bought at a swap meet years ago, date coded 7A. It has the round 3-contact connection usually seen on Corvette transistor ignition amplifiers, but points horizontally. You need a separate field relay for this unit, unlike the 368 or 378 VR's that Joe mentions (they have an integral points on/off relay).
I have the box and instructions dated 6-10-69 for my 9000590, will copy latter if that will help.Comment

Re: These may have been used on school buses
9000590 was a HD truck application. We ran 25 trucks with the regulators on them. Was a full time job keeping them repaired. My guess is the output transistors were somewhat like the TI units. Were not very reliable. Also probably vibration and maybe poor grounding contributed to this problemDick WhittingtonComment

Plus...
There have been some VERY EARLY L78 (396) cars seen with the transistorized voltalge regulator on them. If memory serves, there was an NCRS member doing survey research in this area.
The general 'drift' was certain AIM references under L78 (e.g. 'installs the same as C60') caused initial confusion on the assy line and some early BB cars left with solid state vs. electro-mechanical voltage regulators on them. How much is true and what's 'urban legend' I can't say....Comment

TI Volt Reg on 396 Road & Track test car
... appeared in engine compartment pic of a road test that appeared in their August 1965 issue, but as Jack H. pointed out in a post a few years back, the upper rad inlet (NOT a curved neck) and upper rad hose indicate an early L78 car (up to ~ VIN 16200).
Good shot of same road test in Noland's Vol 2, page 280.Comment

Re: ELECTRONIC VOLTAGE REGULATORS
Joe, I believe these are fully solid state and can be found in the assembly manuals for '65s.Comment

Re: ELECTRONIC VOLTAGE REGULATORS
368 regulator and 590 regulator have a totally different case. 590 uses same case as TI amplifier (don't ask me how I know). 368 is unique shapeDick WhittingtonComment
