Good Morning. Well, I tried to replace those two flashers, and actually pulling that board like you said Waderade812 was pretty easy. Unfortunately, the bulbs are good, and the traces look good. I visually checked all the resistor boards for broken leads as suggested by GRUMPY and saw no broken leads. Can anyone tell me which resistor board(s) is for lights 03C and 04C? I read thru a lot of the posts for these flashers being out and in looking at the matrix on the 1st page of the manual, well, like any of the other matrices, they leave me scratching my head. I will try to apply the technique of jumpering the two larger resistors once I find out which board, to determine whether it's a resistor problem or a diode problem. Now, one question. Should all those resistors have continuity? If so, that would be an easy check without having to jumper and then turn the machine back on. Lastly, if I ever do decide to go LED on the flashers, I understand that I must either snip off the smaller warming resistors, on the outsides of all resistor boards, leaving the two in the center intact, OR unsolder the ground wires from all the resistor boards. If I do the un-soldering, do I un-solder the ground wires from both sides of the board? I've noticed a couple boards have the ground wires soldered on both sides. Enough for this morning, I'm at work, and won't be able to try any suggestions until tonight, so please be patient with me.
Thanks,
Chris
