2001 Arctic Cat 250 4X4 -- NO SPARK, PLEASE HELP

[mphjr86]

Usually I never ask for help on the Internet, but this thing has me stumped. 2001 Arctic Cat 250 4x4, I bought it from a friend, he said it ran good a week before he sold it to me. I have taking apart all the plastic/ racks. I have no spark to this machine at all. I have replaced Two ignition coils, checked the Harness for any bad spots, checked all fuses/ replaced them just because. Changed spark plug, changed Two CDI boxes, Good battery, I have checked and bi passed all neutral safety switches, and still no spark. I hooked up my Multimeter on the single wire coming into the coil and I'm getting about two volts pulsating when using the push button starter, I have also tried pull starting, and still nothing. Please if you could help me in some way in would be appreciated.. Thank you

stator ?

[mphjr86]

Well I thought the same thing so I took it apart and checked the magnets on the flywheel, I was going to replace the stator, and my local dealer tells me, don't replace the stator because it has nothing to do with it starting or firing. He tells me it only charges the battery and keeps it up while it's running. Is he full of crap.?

hmmmm ... i would wonder where the spark comes from then

stator and/or pick up coil could be bad ...

Pickup coil tells when to fire the spark plug. Had a broken wire on one with a machine and that caused a no spark issue.

Well thank you to all who responded, I'm going to change the stator and pickup coil. I will let you know how I make out

[mphjr86]

Well today is Friday. I installed a brand new stator with a new pickup coil, another new ignition coil, and another new voltage regulator. I still don't have any spark at all.. I am sick of this thing. Any ideas.?

Damn !!!

It must be a bad/broken wire or connection plug ... you have dash lights and the starter works I assume ?

[mphjr86]

Well I checked all the plugs, pulled all the tape off the harness, cleaned thoroughly. Didn't see anything bad. My neutral light and reverse light won't light up on the dash. But I have tried bypassing all the neutral safety switches, and still nothing.

[mphjr86]

Yes starter works great, I cannot even get a tiny spark at alll, that's whats weird.

Sounds like some of the issues I've run into before and it's always the simplest thing and you'll feel stupid and like an idiot for overlooking it when you do find the problem. The problem I've had similar to this was a kill wire grounded or a kill switch. You might just have a key switch that kills it along with a kill switch that is in the off position.... find all kill wires and disconnect them. If it starts right up you'll know how crazy you are for overlooking the simple answer.

[mphjr86]

I know, I feel that its something simple, I have tried bypassing all kill switches, including the one on the handle bars and all the neutral safety witches.. This thing is irritating lol.. Unless the CDI boxes I purchased are no good, that's all I can think of.

[mphjr86]

See if the kill switch on the handle bars is off the starter won't try turning over at all, same thing if it's in gear. I'm just to the point where I want to drop it off a cliff.

[RandyJ]

I'm not at all familiar with Artic cat but every small engine I've ever food with (a few thousand, including outboard motors) has a kill wire that goes to the igniter or whatever you want to call that box the spark plug wires come out of. If it is grounding the circuit which produces the spark then it ain't gonna spark. Disconnect the sucker and see what happens.... if that gives you spark then work back from there. It could be the kill wire in the switch or the switch itself having a short in it. I've been through this several times on old outboard motors.

[mphjr86]

Ok I will give that a shot. A quick question for you.? Is there anyway to bypass the CDI to say somehow jump the coil to get spark. I don't think there is, but I will just throw it out there.

[mphjr86]

Figured it out, it ended up being TWO BAD CDI BOXES, YES TWO.. I replaced it with another one and she fired right up and purred like a kitty.

I would have never thought 2 cdi boxes would have been bad from the start ...

congrats on getting er going !!!
