Flasher questions

[Michael J.]

I am going through the punch-list of judged deducts from my last judging, replacing parts on my '67. I was dinged for replacement turn-signal and hazard flashers. I ordered a yellow, non-DOT '67 turn signal flasher and installed it. I could not find a hazard flasher that wasn't a repop. However, it made my replacement hazard flasher quit working. When I put the replacement (NAPA) turn signal flasher back on, the hazard flasher works again. I am wondering if there is another hazard flasher that will work with the yellow, non-DOT turn signal flasher, or maybe if I order another of the yellow, non-DOT ones that that will work and not lose points. Any ideas welcome, thanks.

Michael - Interesting. It sounds like something is shorted out in the yellow non-DOT turn signal flasher. My experience has been that any good working hazard flasher will work with any good working turn signal flasher and visa-versa. Pete

Re: Flasher questions

Thanks for the help, I will look into that.

Here is the same hazard flasher I have in my '67. It should work with your non DOT Tung Sol 323 signal flasher and you won't lose any points, at least I didn't. PT

OK, great, thanks. I guess I will also need a new flasher holder, as the one I have is for a round flasher.

Re: Flasher questions

Mike - Please note that the clip for the turn signal flasher located on the radio side panel is designed (those clever engineers) to hold the round cover and rectangular cover flashers, i.e., one size fits all. And you can take that to the bank. Pete

Re: Flasher questions

Patrick - The Signal-Stat 175 you show is an excellent example of one of the original 1967 Corvette hazard system flashers and should be mounted directly in the Fuse Panel and for sure not receive a deduction. What Mike is looking for is the turn signal flasher which would be mounted in a clip on the Driver's side of the Instrument (Radio) Panel Trim. Pete

Correctamundo, on closer examination, I now can see that. Thanks Pete.

Michael,

I agree with Peter, the hazard flasher and the signal flasher are independent of each other. They are on completely different circuits which come together at the signal switch in the steering column.

When you push the hazard switch on the column in, you are disconnecting the turn signal circuit, and connecting the hazard circuit to the front and rear signal lights.

It would be odd that one flasher would effect the other, but I learn something every day.

Maybe you have a fuzzy hazard switch in the column.

The retangular hazard flasher goes on the fuse panel. I have my original hazard flasher on my 67, on the fuse panel. It is the circular one, still works just great.

Re: Flasher questions

Patrick,
What is the date code on your "gold" 175 Signal-Stat flasher? Enclosed is a picture of a used (aluminum with green printing) 175 Signal-Stat flasher dated "S407" (Syracuse, possibly the 40th day of 1967?) that I found in a 1968 Camaro (VIN 124378N339894) about 20 or 25 years ago. It may or may not be original equipment.

CORRECTION: "S 407" = 40th week of 1967, late Sept.-early Oct. 1967.

I also have a NOS "gold" 170 Signal-Stat flasher dated "S 196" (Syracuse, possibly the 19th day of 1966?) and a NOS "gold" 145 Signal-Stat flasher dated "T 444" (Toronto, possibly the 44th day of 1964).

CORRECTIONS: "S 196" = 19th week of 1966 and "T 444" = 44th week of 1964

Terry, thanks for correcting me.

Dave,
NOT days of the year, but WEEKS of the year. You will not find one dated higher than 52, or possibly 53 in some years. Be cautious -- the date codes changed in 1968 just for us C3 guys.

David, here is my Signal Stat #175 with a greenish tint. The date number is 7-257. No matter, it passed judging. The '67 Judging manual calls out for a Signal Stat gold finish #170 or the Signal Stat green finish #175. They do not call out for dates because you can't see them when the flasher is installed.

I'm guessing that this 175 flasher I have is probably original. If it had been replaced, it probably would have been some off brand flasher like NAPA or Wagner. PT

Re: Flasher questions

Patrick,
Your "175" flasher is dated "T 257" (Toronto, 25th week of 1967). I would say is is an original factory installed flasher for a 1967 (late June 1967). I can read the code from your picture. Terry just corrected me on the date code.

David, my '67 is a very late July car, build date L06 (July 6th) VIN 22526. So a late June '67 date would be just right for my car. PT

Re: Flasher questions

Patrick,
I guess this verifies the date coding thanks to Terry's correction.

After doing a little more research my NOS Signal-Stat 170 hazard flasher (dated "S 196" or Syracuse, 19th week of 1966) is GM # 3843741 which was discontinued in April 1967 according to Chevrolet Parts History and replaced with GM # 3883794 (Signal-Stat 175).
