Re: need help with m&w pro 10
If the LED is coming on initially, then not flashing after each trigger event.
Test by triggering Pin 15 Trigger A(ECU) too ground too trigger the coil. Make sure that you have a grounded spark plug when testing. If the CDI box triggers the coil. You have one of 2 problems. Either the ECU is faulty and not triggering the CDI box or you have a bad connection. Or your Ignition switch wire is not powering the CDI box during cranking. If the unit doesnt trigger. You either have a bad CDI box or a bad Coil.
Im probably going to lean towards a wiring issue with either the trigger wire or the ignition switched +12V wire.
Hopefully you can get it figured out. On a side note I would also recommend running shielded twisted pair wire for the Power/ground and Coil +/- wires too help with Interference.
