I have just picked up a no fear and the launcher is not working (wasn’t working when I got it).

I have just noticed that the coil installed has a diode on it. I thought that WPC machines did not require diodes on the coils outside of the flippers.
I have also checked all fuses, transistors with DMM and continuity. There is also power at the the coil.

Could the diode be the issue.

If it is on and the coil wired wrong, yes it could have caused some board problems.

Ok thanks. That is what I thought.

The transistors all look ok on that circuit and have connectivity to all the correct connectors and components. Would it have potentially taken out U5 for that circuit.

Check it with a meter. Won't be shorted, might might read different than others by it.
