TheBryan35 Posted December 17, 2020 Report Share Posted December 17, 2020 I cut pin 7 it slowed the flash down I only had Rear LEDs when i switched the fronts to LED it would not flash at all, just one click and no ilumination, when i switch the front back to incandecent bulbs everything works fine again, i also tried flipping,the led around and,no change any ideas, also what does the u60438 pin in the picture do? do i need to cut that too?

someotherguy Posted December 17, 2020 Report Share Posted December 17, 2020 U60438 is the part # to the chip itself, not indicating any leg of it to cut. The only one you wanted to cut was the #7 pin that you already did. Weird symptom.. what if you swap the arrangement around? Incandescent out back, LED up front? I guess the only thing I would really caution you against here is not to remove/reinstall the LED's too many times as a lot of them seem kind of weak where the leads go up into the assembly, that's where I've seen more than a few break off. Are you 100% sure you got the correct part # on the LED's.. should be 3057/3157 style (dual function) front and rear. Richard Quote Link to comment Share on other sites More sharing options...

But as you see the modded one isn't terrible for being free. You Clip the #7 pin on the inside, bottom left of the board. If I can find the pic I'll post Edit: Quote Link to comment Share on other sites More sharing options...
meisenman67 Posted March 21, 2021 Report Share Posted March 21, 2021 I inserted the block diagram of the Atmel U6043B Flasher IC to where pin 7 falls in the circuit Quote Link to comment Share on other sites More sharing options...
