I have a 1978 Arctic Cat Jag 3000 (340 cc). I bought it at an auction and when i brought it home, i put a new fuel line on it and it fired right up several times, until one time it quit. After pulling out the plugs and testing for spark, there was no spark at all. Where there used to be a key switch, a toggle switch was installed to replace it. The toggle switch seemed old so i replaced it and still no spark. I had the Coil tested and it is good. So is it the CDI box, and is there a way to find out before i by one? What other things could it be that would make it have no spark. And is theree a way to by pass the ignition switch and the kill switch. there is 2 brown, 1 black wire, that were atached to the 1st toggle switch and 2 green wires that were not!! Help i want to get this beast up and sparking again!!!!
