TUNG-SOL Flasher

[John F.]

Is this flasher correct for an early 62 (#29)? TUNG-SOL FLASHER, AP376V--12 VOLTS, 6 8 1, PAT. 2615106, MADE IN USA, two prongs with 3 LAMP on the top in a circle?
After further clean-up with a light wire brush it is in fact an AP373V--12.

Re: TUNG-SOL Flasher

John,

I don't think thats the one. I think you are looking for a rectangular shaped Signal -Stat, ZN332 - 12V, 3 lamp. If you need a jpg let me know. Others may know better, but that's what I have on my October 9, 1961 built '62.

Re: TUNG-SOL Flasher

John, I think the one you have is a AP373V witch is correct for your car.

Re: TUNG-SOL Flasher

1961-1963 Corvettes and certain other 59-63 Chevrolet models used a GM # 3758682 flasher. It was made by 2 different vendors with 3 different part numbers as follows:

Tung Sol AP373V
Signal Stat ZN332
Signal Stat 143

I have had one NOS ZN332 and one NOS 143 in GM yellow & gold boxes with the same GM part number, 3758682. My 1963 Chev. parts catalog (Oct. 62) lists the AP373V flasher as GM # 3758682.

The "can" length of a AP373V flasher measures 0.87" in length. I have had many NOS AP373V flashers in Tung Sol boxes as well as several that were used from junk yard cars. The date code has yet to be decoded by anyone as far as I know.

Re: TUNG-SOL Flasher

David & Kevin, Thank you for the info. I took a light wire brush to the can and it is an AP373V--12. I can see it with the manifiying glass now. So I guess it is correct for my car!

Re: TUNG-SOL Flasher

Are all 3 of these correct for a 62? (in my case a May 62 built)

Tung Sol AP373V
Signal Stat ZN332
Signal Stat 143

Or just the Tung Sol AP373V one?

Thanks,

Tony

Re: TUNG-SOL Flasher

I believe all 3 are correct but you should check the 61-62 judging guide to see what will judge correct. Kevin (775)

Re: TUNG-SOL Flasher

In theory all 3 are possible. The one most often seen in Bowtie cars is the ZN332.

Hope this helps

Re: TUNG-SOL Flasher

I don't see anything in the Judging Manual, unless I missed it.

Re: TUNG-SOL Flasher

John - If you haven't already, look in the AIM and see if there is more than 1 part number called out for the FLASHER ASM. I know in the 63-67 Corvette AIMs there are 2 flasher p/ns called out, i.e. ####### FLASHER ASM &
####### OPT if back up lamps were standard equipment and on cars where BU lamps were not standard, there are 2 p/ns called out in the FUSE PANEL UPC and another 2 p/ns called out in the UPC where the BU lamp accessory is describe.

Remember the cars were generally built according to the AIM not to the TIM&JG. Also, remember GM was in business to make $$$$$$$$ not cars, and failure to have a single source supplier for an item like a flasher which if the supplier had a problem would cause production not to be able to ship cars wasn't a good idea.

Re: TUNG-SOL Flasher

The 1962 AIM (Sect. 12, sheet 12.00) lists 3758682 and 3758683 as the GM part numbers for the flasher.

Re: TUNG-SOL Flasher

Dave - Thanks for the info. I'd say with 2 part numbers being called out in the AIM that the Signal -Stat, ZN332 - 12V, 3 lamp flasher isn't the only flasher used in production, although it might have been the predominant one. Pete

Re: TUNG-SOL Flasher

Pete,
Back in the old days (1950's & 1960's) when GM used the gold/black boxes the ZN332 and the 143 flashers came in the same box with the same part number, GM # 3758682.

Re: TUNG-SOL Flasher

Dave - I just checked my Oct. 1, 1966 P&A 30 and it shows 3758682 as FLASHER, controls 3 bulbs only (AP373V) which is a Tung-Sol flasher. I thought I had seen an old box with the 3758682 p/n with a Tung-Sol flasher in it. I will check. So many flashers and so little time. Pete

Re: TUNG-SOL Flasher

Pete,

As best as I can remember the two NOS flashers (ZN332 and 143) pictured in the gold/black 3758682 GM boxes are now in your collection instead of mine.
