Warrior 350

Warrior spark issue

Recommended Posts



Welcome to Quadcrazy, is the ignition switch new? Replacement?  Maybe damaged? I would take it out and inspect the switch as well as any crossed wires.  See if someone removed the plug and maybe hardwired it ?

It sounds like something is back feeding power into the ignition circuit somehow. Maybe an accessory? Plow lights of some sort ? I would get a tester and see what wire gets power at the ignition plug when you turn  the ignition off and trace that back.  Also check the entire harness for damage. Wires get hit all the time or areas where the harness is rubbing against the frame of the bike wear away the tape and insulation. After that i would start checking the stator coil, regulator, and secondary coil with a tester for proper ohms that’s shown in the repair manual. If you are not sure how do do that we can kinda walk you through it or check on YouTube as well it’s very helpful

The new ignition switch is wrong switch. This just happened to me. I bought the cheap $10 one on ebay or amazon. The correct switch should be normally open on both circuits where as the cheap new one I bought is normally open on one circuit and normally closed on the other (which is the way many other atv ignition switches work). One circuit is to turn positive battery power on and off, the other circuit is a ground wire for the CDI. I corrected the issue by connecting the two wires for the CDI circuit. The ignition switch is now only used to turn on and off battery power, it does not kill the engine. The only way to kill the engine now is to use the kill switch.

I appreciate the help guys I ordered new parts just waiting on them to get here someone before hacked the wiring harness so I bought different one along with a factory ignition stator and cdi hoping I can get it going

The only part you need is a OEM ignition switch.

On mine, all I did was hack into the wiring thats part of the faulty ignition switch, I did not hack into the atv wiring harness

If you are really good with switches, you can try to disassemble and clean the switch, usually its just the contacts that get corroded or dirty. My switch showed 150 ohms of resistance on the cdi side when it should be under 1 ohm

Or if you want to be getto, you could use two seperate switches. Use the old switch if it still has a one good circuit and the new switch for the other circuit

Cant test CDI, need to test everything else before you can suspect CDI, you can replace CDI with known good one. CDI is under the front body plastics, inbetween and above front tires...I think

Ya I had my buddy test everything else on it and put the cdi on his and his didn't have any spark either so figured it was shot his works and I get spark but he rides his often so can't take his lol

Do you have a multimeter? measure resistance on main switch, black to black/red, and red to brown. Both should have continuity when switch is on and no continuity when switch is off

      Hello I am new to this site and I havea problem. I have a 1987 big bear 4x4 that will not spark. I tested pick up coil per repair manual and I tested my new coil both ok. It puts out 9 volts at the coil but It is reversed polarity. So when I hook my meter up to it she shows -9 volts while cranking. When I put a test light  on it it flashes. Being an electric system this should tell me something but I don't know what its telling me. I have yet to meet one i could not fix but this old girl has me stumped. Any help would be awesome. Thanks to all.

      1997 Yamaha 350 Warrior, should there be oil in the stator area? Have a no spark situation.

      Hey guys I'm new here. I have a 88 warrior that has intermittent spark. When I got the bike the guy said it needed a stator.  So I tested the stator and the Source coil has .310,  Trigger coil has .363 an .367,  Alternator side has .05 to .06 on the three. Which all seem in range. I did find that the ignition coil was bad and replaced it. After I  put the new coil on i got spark but only now and then. The bike won't spark while I'm holding the start button,  but as soon as I let off it will spark sometimes. I ended up unplugging the voltage regulator and it will spark every time I let off the start button, but still will not spark while I'm  holding it. What could this be?

      my buddys 02? warrior cuts out as soon as you give it throttle. it stays running, but it missfires and pops through the exhaust. it returns to idle and idles fine. the timing looks ok and we have swapped the carb with no change.its been sitting a while waiting on carrier rebuild, it ran fine before that. any ideas?
