Clone kill relay wiring diagram

[sho305]

Made a simple diagram for wiring kill relay to a clone in a cart when using stock starter/generator. This only works if you get 12v hot from the pedal when pedal down, and no power when pedal up. Yamaha are wired this way far as I know. G2/9 use a white/red wire to power ignition from the pedal to run. This setup will kill the engine all the time unless you press the pedal to power the relay. You must use the 5 pin relay, the 4 pin will not work. Most older GM cars have these relays under the hood if you happen to hit a junkyard.

If you also get the plug and harness you can pull the relay to make the engine run, such as for recoil starting. If you wire with connectors then pull the engine block ground wire #30 to make it run. Relay and harness are cheap online if you can't find local; mine were $3 each at amazon back when I wired mine.

You can turn the idle off to kill the clone but if your throttle linkage ever sticks or breaks you could have a problem, this relay kills the engine for much safer operation. Wired this way it uses no power at rest, it will run with the stock pedal start and generator just like stock.

People ask me about this so maybe it can be a sticky in clones. Please check my work and try to run your cart today

I should add one thing: never put power to the kill wire on a clone or any lawn engine with magneto ignition (coil on the flywheel magnet and needs no power to run). Most of the time it will waste the coil! Wired this way 30 and 87a are connected all the time unless the relay is energized, do not allow 12v to touch 30 or 87a (the kill wire). 12v power goes through 86 (switched power) to 85 (ground) to power the relay, and have nothing to do with 30 or 87/87a pins. If your clone has a charge system like most electric start, don't use that wire as the kill wire. The kill wire goes to the coil not under the flywheel where charge coils are (if equipped). Recoil clones usually don't have any charge coil. The kill wire may also be connected with the low oil shutoff switch in the side of the block. The oil switch grounds the kill wire when low oil.
