    Re: Part No.help 63 Flasher

    Just found my spare, aluminum colored SIGNAL-STAT 143 12V 3 LAMP flasher.

    The number on the bottom side is T0164. I have no idea how anyone could read that when installed.

      There are some threads about flashers and date codes but I doubt that you will find that anyone has decoded the Tung Sol AP 373 V flasher. If you find something let me know.

        Just replaced what I thought was the original Signal Stat flasher in my coupe. Car has original PW, PB.

        17?
        T48/
        12v flasher


        curious as to how to determine the date?

        I see an L in the upper right circle and an X in the lower center circle. Would the placement and letters be the date code?

          It's also worth mentioning the correct flashing rate with the 1034 bulbs and the 143 flasher. If 1156 bulbs are used the blinker flashes much faster, big difference.

              Great idea. The outside of the flasher is not suppose to be hot. It becomes hot when the paper tears between the flasher and the socket and contact is made. At that point, if the cable is touching the flasher a direct short happens and things start to burn.

              Don't ask me how I know. I'm going to add that rubber tube/hose!!!

              Thank You Chuck...........
              I thought it was a good idea. When I took out the incorrect green Signal Stat, I could see where the cable had been rubbing it. The TS flasher is bigger yet. I "think" it was you who gave me the idea about protecting it. I recall hearing something about your "electrical issue".

              Tim's correct, and it was Tim that put me on to the correct 1034 bulbs. I picked up a 12 pack of them at a flea market. Interesting that they were packaged in a Texaco bulb box.

              I don't think it's the Florida weather, JD. I've only been here for 1.5 years. My fuse box is a "survivor".

              I seem to remember discussing that the TS flasher was much more common, and that IF a SS flasher was used, it was the natural aluminum color, not "anodized", like the green, purple, etc. colors you commonly see. I've never seen a natural colored SS 143 flasher.

                    Re: Part No.help 63 Flasher

                    Wasn't the 1034 replaced by the 1157 (not a 1156)?
                    As for the flashing rate is everyone saying that if a 1156 is used as a backup light with 1157 directional lights then the rate is wrong (faster)?
                    Confused here!

                      Thank you, Jack.

                      That's the first and only one I've ever seen. I've seen lots of colored ones, green and purple seem to be the most common colors I've run across.

                        Alan,

                        I make a mistake, my post should read 1157 bulb NOT 1156. Sorry..

                        The flashing rate is when the correct 143 flasher is used with the later 1157 bulbs. The 1157 bulbs must draw more amps and the flasher will open and close about twice the speed as when used with the correct 1034 bulbs.

                        I believe 1964 started with the 1157 and a different flasher, I don't know the part #.

                          Alan,

                          For the 50's to the end of 63 production, the 1034 bulb was used for T-Signal/brake lights.
                          Beginning with the new 64 model, the new 1157 replaced the old 1034.

                          The new, brighter 1157 bulb required a new/different rate T-signal flasher.

                          If the new design 64 flasher is used in a 63 model with the old 1034 bulbs, the flash rate would be very slow.
                          If the old design flasher is used with the new 1157 bulbs, the flash rate would be very fast.

                          That's why the parts book is very clear on the different usage of bulbs and flashers for 63 and earlier, and 64 and later. It was also "highly recommended" by GM that the new 1157 bulb not be used in 63 and previous models because electrical system damage could result.

                          If I remember correctly, the 63-64 JG shows the 64 flasher as being used for 63?

                            Michael, the JG shows the 143 being used for 64 3 lamp, should be a 145 or 323. The 224 is correct for 64 with backup lights, not a 145 as shown. The JG also shows a 373 for 64 w/o bu lights, it should be a 323.
                            My vote is:
                            63 w/o bu lts: 373 or 143 (1034 lamp)
                            64 w/o bu lts: 323 or 145 (1157 lamp)
                            64 w/bu lts: 224 (1157 lamp)
                            63 w/bu lts?

                                Here's what GM had to say about the "new for 64" flashers and bulbs etc. This was released around July of 1963 for the 64 model year.
                                This is also why the part numbers on all wiring harnesses and the voltage regulator changed for 64.
