Re: Force 125 ignitions problems
Jumpering the kill switch enables the kill switch function. The Kill switch is normally "open" with the lanyard clip on it. When you pull the lanyard clip off, it closes the contacts and shorts the ignition circuit to ground killing the voltage to the CD modules/coils.
Look on the terminal strip in the port side o the motor by the starter. I believe the third terminal down there should be 3 white wires. Later models have Black w/yellow stripes. With the ignition switch in the on position, not start, you should read very high resistance between the terminal and the block (ground). With the ignition switch in the off position, you should read continuity (short) between the terminal and block (ground). If this checks out, then your kill circuit is functioning normally. If not then you have a problem in the kill switch wiring, or ignition switch. Something is probably shorted to ground.
To do a quick check of the CD Modules you use the same wires. Pull the plug wires off of the plugs so the engine doesn't accidentally start and ground them to the block. Look at the three white wires (Black w/yellow stipe on later model). Two go across the top of the motor, one to each of the two CD boxes. Disconnect these two wires and crank the engine like you are trying to start it. Check for spark at the same time you're cranking on the plug wires. If nothing, then the problem is probably somewhere else, not the modules. If you do get spark, then one of the CD modules may be bad. A bad CD module that is actually working, can prevent a good one from firing. The best way to check them though is with a DVA meter.
