Re: Johnson 200GT No Spark 1-3-5 spark 2-4-6
Check the resistance and DVA voltage for the bank without spark on the 6 pin stator connector while connected as follows:
Red Lead: Black Lead:Ohms Resistance: DVA: Bank/Cyl
Brown: Brown/Yellow: 450-600 ohms: 150V +: Stbd (1,3,5)
Brown/White: Brown/Black: 450-600 ohms: 150V +: Port (2,4,6)
NOTE:The first set of numbers will apply to you since it is your starboard side not firing. If the power pack has no spark on one bank and the readings are good, replace the power pack.
Disconnect the 5-pin connector on the port side of the power pack and see if the spark returns. If it does, use the CDI meter set to Ohms and see if the Black/Yellow or Black/Orange wire is shorted to engine ground. Check to see if the Shift Interrupter switch is located in the circuit where there is no spark.
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 reading is low on one bank, disconnect the orange wires from the ignition coil for that bank and reconnect them to a load resistor. Retest. If the reading is now good, one or all of the ignition coils are likely bad. A continued low reading indicates a bad power pack.
