Disconnect the black/yellow stop wire and retest. If the engine's ignition has spark, the stop circuit has a fault-check the key switch, harness and shift switch. Check the cranking RPM. A cranking speed of less than 250-RPM will not allow the system to spark properly.The kill lanyard is clipped in secure correct?
Check the stator and trigger resistance and DVA output as given below:
Wire Color: Check to Wire Color: Resistance: DVA Reading
Brown wire: Brown/Yellow wire: 450-550 :150V or more Connected
Black/White wire :White/Black wire :15-42: 0.6V or more Connected
Some engines use the following wiring on the trigger:
White wire: Blue wire :15-42: 0.6V or more Connected
White wire :Green wire :15-42: 0.6V or more Connected
Check the DVA output on the orange wires from the power pack while connected to the ignition coils. You should have a reading of at least 150V or more. If the readings are low, disconnect the orange wires from the ignition coils and reconnect them to a load resistor. Retest. If the reading is now good, the ignition coil is likely bad. A continued low reading indicates a bad power pack.
before you spend too much time on it, MAKE SURE THE SAFETY CUT OUT IS CONNECTED!!!!! seriously, this happened to me out on the lake, paddled all the wya to shore and had the motor half pulled apart, then we noticed that it was just the cut out.....
