symptoms of a bad cdi box
what are some of the symtoms of a bad cdi box or one that is "going" I have a 300 bayou which is amking a chattering or noise which comes and goes. it kidnd of sounds like somethig is rattling around insode the engine. I brought it to my local kawi. dealer 2X and neither time they didn't hear any noises, but as soon as I got it home the noise was there. when I explained it to them they thought it might be the CDI box going bad and the noise I was hearing was a spark knock ???? thanks in advance

You don't say what year model you have,but pull the black wire from the reverse limiter module if it's a 99 or earlier model. If that doesn't help then pull the black wire from the cdi to isolate the kill circuit. If that helps on starting then the problem could be in the ignition switch,the left control switch or the cdi kill circuit itself. Plus you can ohm out the pulse coil white and white/red wires. Should be around 97 ohms. If it pulls starts easy,but hard to electric start,the gap of the pulse coil to the flywheel could be off. Here's what another member found out when he had that problem. no spark to plug when using electric starter - Page 3 - ATVConnection.com ATV Enthusiast Community

Bad cdi box
I'm having problem with my 2002 Polaris sportsman 500 ho, the seems to keep running burning it out. I noticed the black wire on the cdi box is rehooked to a toggle switch. If switched to off position it runs ruogh at high rpms and also won't shut off, yet when flipped it runs great but seems starter still gets power. Help please
