Re: Losing spark
How are you checking for spark? Are you using a meter or are you just holding the plug to ground and watching for it?

If you google igniter test and such there are lot of troubleshooting tips posted on a bunch of different locations. I'd bet you can find a test somewhere if no one here knows anything specific. I am pretty sure these carts are set up pretty much the same at most motorcycles / quads of the period. My son has a Suzuki quad that has the same set up as my G1 (different components of course). |

Re: Losing spark
The Yamahas are a tci system, not a cdi. The coil is charged all the time and releases the spark when the connection is broken. Most coils are a cdi coil so they will not work on a Yamaha. Check out some pictures of a stock coil and compare it to yours.

Re: Losing spark
If it were me, I would find a wiring diagram and put all the wiring back where it belongs the best that you can. I personally think you are fighting a wiring issue, especially since you bought the cart under repair. I would bet this is something that is stupid simple and it's hard for me to help you over the web. There are some good wiring diagrams online to look at. I would definitely concentrate on your ground wires.
