My pamco ignition is not sparking on either side. I followed the following troubleshooting steps:
Testing the coil:
1. Using the lowest scale on the meter, measure the resistance between the primary terminals with the wires removed. Should read from 2.5 to 4.5 Ohms.
2. Using the highest scale on the meter, measure between one of the primary terminals and the center core of the coil. Should be infinite resistance. (open)
3. Measure between one of the primary terminals and one of the plug wire terminals. Should be infinite resistance. (open circuit)
4. Measure between one of the plug wire terminals and the core of the coil. Should be infinite resistance (open circuit)
5. Measure from one plug terminal to the other. Should be 15,000 to 20,000 Ohms
Testing the PAMCO
1. Use a voltmeter and check for battery voltage on each of the red/white wires with the key and kill switch are turned on.
2. The dual output coil has to have both spark plug wires connected to a spark plug at all times.
3. To test for spark, connect one of the spark plug wires to a spark plug that is grounded to the engine.
To test for spark without having to turn the engine over, do this procedure:
1. Remove the PAMCO rotor.
2. Remove the locating pin in the advance rod.
3. Reinstall the rotor, but without the pin.
4. Replace the nut holding the rotor on loosely. This will allow you to spin the rotor to produce a spark without having to turn the engine over.
5. Connect one of the spark plug wires to a spark plug that is grounded to the engine, but not installed in the engine.
6. Make sure that the other spark plug wire is connected to a spark plug in the engine.
7. Turn on the ignition switch and the kill switch.
8. Spin the rotor while looking at the gap in the spark plug for a spark.
9. Turn off the kill switch and the ignition switch.
Coil resistances check out ideal. Voltage to red/white wire is not ideal. Battery voltage at rest (ign off): 12.50. Battery voltage with ignition on, kill switch on, headlamp lit: 12.21. Voltage to red/white 11.72. When I turn the pamco rotor, voltage at red/white alternates between 10.33 and 11.72.
Both plug wires are attached, one in engine, one grounded to engine. No spark.
Does this mean my pamco ignition is toast? Or is the voltage drop a possiblity? (it sure needs rectifying, but maybe it should still spark)
