Only thing left on my grand lizard is the 3 bank flasher doesn’t work. I changed bulb , checked the small board for loose wires.
It looks intact. There are two resistors on it can a bad resistor cause it not to work?

Thanks for the reply. I know what to check next then.

Will check that too..ty
My thinking is the orange and red are power and the white purple is the cpu control ?

Does the resistor on the board control both of the flashers in the photo? that are tied in with the yellow?
And thanks. I will use that to test them

I think I tried new bulbs in both.. but will make sure. I will check the resistor and the solder joint as well

Thanks. Even I can’t mess that up
Do I need to be in the test mode, testing that flasher to Do that or just with power on?

As it think about it must be just power

Ok. So both bulbs
Light when I jumped red to green. They also light green to yellow.
Does that point to a tip on the board. ?

Now it’s working. I don’t get it must be one of the solder joints as pointed out as well. All I did was move things

I ordered new resistors. Will replace to be safe. Thanks
