Kill switch info

[Andrew 4CE]

All my stuff is in storage for winter, be snowing here soon... The kill switch on CDI ignition... is the kill switch an open circuit when the tether is plugged in? When the tether is pulled it closes the circuit, it shorts something and the motor stops correct? So is there any voltage/amperage going through the kill switch wires at any time? If so, anyone know how much?

Thanks,
Andrew

The kill switch is an open circuit when the key is installed. Nothing is going through the open circuit at that time. . When the tether is pulled and the key removed, the circuit becomes a closed (connected) circuit and grounds out the ignition. . In the 102 and Y-80 the two sets of points are connected via a kill switch when the key is withdrawn. The 302 is a different set up and grounds out each cylinder spark individually when the key is removed. Jack

Thanks for explaining the operation guys. Solved my issue.

On modern engines, such as the OMC-A and the Sidewinder, the CD ignition does put a voltage on one leg of the kill switch circuit, so be sure the wires, joints, switch, and connector are in good condition.

One fix is to put a daub of silicone seal on any exposed contact of the switch wiring. That'll waterproof it against any possible inadvertent grounding of the ignition because of spray or other water invasion. It'll also shockproof the system from human contact while the engine runs. -- dave w
