Thanks in advance for any help or guidance. I was out riding the other day and lost all spark. I have read every thread on every forum that I could find and have not found an answer. I have checked the codes and its 00. I have ohm metered the stator and crank sensor. I have also replaced the coil pack. I have inspected and cleaned all connections. I do not mud the machine, it is mostly used at the hunting lease for working plots. When I installed the new coil I held the plug on the side of the engine and got 2 little sparks when first turning over and then nothing again. When you turn the machine over like this it eventually flashes EFI on the screen. I checked both wires that go to the coil and noticed that both have ground continuity. While turning over the blue and white one cycle from around 1v to almost 12v. The battery has a full charge and I am at a total loss. I took the kill switch apart and all looked well. Oh yea and all fuses are good. Help me please I am getting very frustrated. Thanks

it should be on the backside of motor ... looks like an oil sending type unit, probably 1 wire ... if the safety switch is damaged, its an easy fix, all it does is allow spark when in neutral ... i have seen some bikes that have a light saying they are in neutral and no spark, replace and spark again ... hopefully this is all it is ....

Just an update, I have ohm checked everything and pulled all plastics off. I haven't found a smoking gun. I am starting to think that it may be the ecm, any thoughts out there on that being the condition? Thanks for the help please

last thing I had do that was an 04 arctic cat 90, did almost the exact same thing, it was the cdi box. have you checked the rectifier? I doubt that's it but I would check it. also it may sound stupid but smell the cdi or ecm, usually if they are bad they will smell burnt.

      Where you like to ride and what riding does for you?

      I like to ride in wooded and grassy areas. It takes my mind off the everyday routines and helps me deal with my father's cancer. Also gives me a reason to get involved with forums like this one.

      Troubleshooting a no spark issue, was running OK, maybe a little rich, turned it off, now no spark. I've checked/ohmed out the main key switch, the start/stop switch, neutral switch, brake switch - all good. It will crank the starter, but no spark with the starter or when I try the pull start. I've checked all fuses and diodes. Swapped battery. New plug. New coil. Swapped in a used CDI - no help. Traced, removed, cleaned, reattached all grounds. Removed things like my winch from the circuits to be sure a bad relay or something was dragging it down. When testing voltages, the orange wire going from the CDI to the ignition coil shows no/very low voltage-shouldn't it have 12V on it? Sometimes I get a very weak, intermittent glow on my spark tester, but not enough to fire the plug. I've checked continuity on just about all wires in the harness. Checked/cleaned/lubed w dielectric grease- all connections, redid a few that looked old/dirty. I've checked the stator resistances, all good, but have a stator and rectifier ordered anyway, will arrive Sunday. I verified that the rectifier has a voltage output back to charge the battery while cranking - 10.5-11V, low, but expected while starter is engaged. What else can I check as part of troubleshooting? I have a Haines service manual, but the 1999 350 4x4 seems to be an odd model, there isn't an exact electrical diagram for it, but found one for another year that has all the same number of wires and same color wires, so I've referenced that. Any hints, tips or advice would be appreciated! Thanks!

      Need help! 1987 Yamaha Moto 4 350
      By P_syko
      I’m brand new to 4 wheelers and just bought a 1987 Yamaha Moto 4 350. It has good compression and fuel, but no spark. I’ve looked high and low trying to find how to test all the components of the ignition system, but can’t find anything. This has a new CDI box on it, but I suspect it might be the stator. How do I test the stator on this? Any help would be greatly appreciated!
