Yeah, I want to use one 1 single fire coil (with two plug wires) instead of 2 green monsters. I have chased down some of my problem and it appears to be with the monster coils. When I hook up the signal wires I have a severe voltage drop, sometimes with just one hooked up and sometimes with two, sometimes if I move the signal wires it will work for a minute, then it will drop. Unhook them and all is good. I have completely started over with the wiring, no wonder this thing did not run too well. Still have not even gottn back to the charging issue. I need it to run decent before tackling that. I am at my wits end for sure.
If you are referring to the green wire from the PAMCO as the "signal wire", then it is NORMAL for it to go low when it turns the coil on. The transistor GROUNDS the coil. It does not provide the power. The power comes from the +12 connected to the coil. Also, only one coil at a time will "go low" when its transistor turns on. The transistor is on in between the 90 degree space between the magnets. So, of you are using the fact that the signal wire goes low to replace the coils, look elsewhere. Like, if the voltage going to the coil "goes low" then that is the problem, not the coils.
Here is a test that you can do to verify that the PAMCO and the coils are working properly without even starting the engine:
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 coils have to have the 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.
