After riding yesterday my reverse light turned on and stayed on. On top of that my Raptor is running rough and back firing. I know nothing about quads. Help would be great before i go spend a shit load at the local dealer/shop. Thanks
The connection has come loose at the reverse switch causing the light and the reverse RPM limiter to come on. Find the green/white wire that plugs into the switch (just below the output sprocket) - it's a push on connector. Unplug, clean all contact surfaces, tighten the spring clamp with pliers, and re-connect.... all should be fine now.
THere is only one green/white stripe wire on the bike, so if you had a green/white in your hand, you had the right one. If cleaning and reconnecting didn't work, there's only a couple of other possibilities:
Okay, then try grounding the green/white wire - take the end that plugs onto the switch, run a piece of wire from it up to the battery negative terminal... does the reverse light go out now? If not, the wire is broken somewhere between the switch and the CDI (behind the battery)... if it DOES go off, the reverse switch is broken. Just leave the wire grounded and you can ride all you want. The limiter will be permanantly off, but so will the light. (do you care?)
