Going through a firepower. Flashers worked util I touched the large resistor and it fell apart. Would like to get these to work with led flashers. Not schooled in resistors. Info on what I need, where to get it and what is needed to make led flashers work is greatly appreciated. Smaller resistor remaining is cooked looking and should probably be replaced.
Thank You

The LED flashers will probably work with the resistor gone from the circuit.

Had you left the resistor in, the flasher would stay lit all the time.

I recently installed LED flashers in my Firepower and had to remove the big warming resistor (as Vid said) or else the flashers would stay on all the time. Upgrade the 2 side lights to LEDs in the FIRE and POWER inserts at the same time if you haven't already. It really brightens up the inserts. Only problem is you will end up puting LEDs under all the inserts once you see the bright colors.

LED flashers do not work with resistor gone. What are the values of the resistors needed for replacement?

There are two resistors on the resistor board for the flashers. The large one is a 330 ohm 2w resistor. This is the warming resistor and usually burns out because current flows through it all the time. This is the resistor to remove if you want to run LED flashers. Replace it with a 5w equivalent.

The smaller resistor is a 1 ohm 1/2w resistor. This is required for the flash lamps to work. See schematic:

The flash lamps are wired in series. This means that if one lamp is bad, neither will light. Also, if the wiring between the lamps is bad, they will not light. You need to check to make sure both lamps are good and that the wiring between the lamps is also not broken. If not, replacing the warming resistor will not solve the problem.
