Sometimes transistors just fail. If you're sending out the board to be repaired, you can take apart the pop bumper and make sure the coil isn't damaged. Check to make sure you can still slide the coil sleeve out of the coil and check the coil resistance to make sure it's within spec.

Finally a response thanks. I am slowley making my way to. Trying to get the led flashers taken care of before I finish the machine.

You'll probably want to look at your ball lock coil, on the cam assembly. I included a pic of my board for comparison.

in coil test all the coils work except that one pop bumper. the switch works so the coil must be bad
