We just bought a 110 CC quad and the ignition switch wiring has come apart. Can someone please help with what order they go in? it has a 4pin with the colors red, green, Black and Black and white. My husband has a soldering iron and wants to try and fix it since it will be a week before replacement part arrives. if anyone can help with the order I would really appreciate it.

 

The ignition switch is actually two separate switches ganged together on a common shaft. Switch #1 turns battery power on and off to everything that runs on DC battery power. Switch #2 is a kill switch. It shorts the kill switch wire to ground when the ignition switch is turned off. This is what kills the engine when you turn off the quad at the ignition switch.

Red: Fused battery power
Black: Switched battery power
Green: Ground
Black/White: Kill switch input to CDI

On your ignition switch turn it to the "off" position. Two of the four wires will be shorted together by the switch. Wire those two wires to Green and Black/White (it doesn't matter which way around).

Turn your ignition switch to the "on" position. The other two wires on the ignition switch should now be shorted together by the switch. Wire those two wires to the red and black wires in the harness (again it doesn't matter which way around).

For temporary test purposes you could just twist the red and black wires in the harness, and leave the black/white and green wires hanging free. The quad should start and run normally, but to shut off the quad you'll have to use the left handlebar kill switch. Untwist the two wires when you're done to keep the battery from being drained.

Caution: The kill switch wire (black/white) has high voltage on it whenever the quad is running. It is current limited (it is gets shorted to ground to kill the engine after all...), but the current is high enough to knock you on your butt. So keep you fingers off that wire when the engine is running.

 

Thank you so much my husband is trying it now.
