my kill switch sometimes works and sometimes it doesn't, is there a way i can trouble shoot it or is better to replace it lmk

You might check the wiring before buying a replacement, especially the ground. If you have an integrated kill switch make sure it has a good metal on metal contact at the frame, some bike finishes have an insulating property and might need to be stripped to insure a solid ground. If your kill switch is a separate component from the throttle it grounds at the handlebar where it mounts…same rule applies if your bars are painted you need to remove paint to insure good ground, also check the rest of your wiring, soldering wire connections and sealing with shrink tubing or liquid electrical tape makes for a much more durable connection than electrical tape alone…hope this helps…Scott

thanks bro that help alot
