Hey, I have just bought this quad. its in decent shape, but does not run. its turns over and is getting fuel and has to what seems to be good compression(just going by finger over the plug hole and turning over. but it wont run due to no spark. i did have it making spark but not very good. where do i start? i put on a new plug wire and new plug what next how do i tet and search things? im new at this stuff diesel engines i know like the ack of my hand but this i am a complete newb. what would be the first thing on a list to check and how tos. all help is greatly appreciated. thanks

The first thing I would do is purchase a repair manual, it will have some direct resistance tests for some of your ignition components as well as a troubleshooting guide. Most likely problem is a bad coil, CDI, pickup coil or just a loose or corroded connection somewhere. A visual inspection of everything behind the stator cover and all the ignition wiring and switches would be a good place to start, but I would strongly recommend getting that manual.

I would check for power into and out of the coil by the use of you ignition diaphram. if you have power in and out then i would test for ground in the circuit by putting the test light to power on the gatorclip and touching the ground wire in the plug. if all is ok then replace the coil. if you had weak spark then no spark i would suspect a wiring issue or a poor battery as well.

      My 1992 TRX00 recently stopped firing.  I understand this is a common problem. I have ordered an aftermarket CDI unit.    TJ

      Hey all, new to the forum! I just bought a 1998 Kawasaki bayou 300, 4x4 not running. Initially I found no spark. Ended up playing with the plug wire (made sure plug top and wiring was touching) and got spark yesterday and the quad fired up off ether. Come to work on it today and now no spark again. Before I got spark and now today if I touch the plug after cranking I get shocked, and it will spark after I release the starter button. I was jumping the quad with a freshly charged car battery that has 12v while cranking. Cleaned out the kill switch and ignition button. All looks good. Purchased new plugs. They're are a lot of wires cut/ disconnected. But shouldn't matter if I got spark without them connected...

      HI everyone. New to this forum. I have 98 Kawasaki Bayou 400 with an apparent electrical issue. I have the Clymer manual, but I am not exactly sure where to start. The issue started a month ago and the neutral light would go on and off intermittently. Eventually it went completely off , and I thought it was a shifting issue. I took the case off and checked the clutch and all mechanical shifting components are good, so I think I eliminated that. The switch sometimes works, sometimes doesn't. Last time I tried, I did hear a clicking sound near where the battery is right before the light went out. Does anyone have any ideas where to start? Hoping this is an easy fix.

      1989 Moto 4 YFM350ERW intermittent spark.
      Quad has set for about 7 years and was running when parked.  When I replaced the battery and attempted to start it had no spark. 
       
      What I have done.  Followed troubleshooting in the manual. 
      1.       Coil failed the resistance check so I replaced it.  Still no spark.
      2.       I performed resistance checks on the stator and they all pass.
      3.       Found a bad rear brake stop switch and unplugged it and connected the wires in order to disable.  Now I have intermittent spark.  I believe that the issue is with either the stator or CDI and not sure which.
      1989 seems to be a transition year for electrical.  I can get new aftermarket CDI units for 87-88 and 90-94.  I cannot get ones for a 89.  I can get new stators for 87-89 and 90-95.  Looking at the schematics the wiring on my moto is closer to the 90 ones on the ATV side of the CDI and closer to the 87-88 on the stator side of the CDI.  Looking at part supply sources the stator housing is the same part # for all the years and looking at some of the stators on Amazon that have the dimensions on them both of the stators are the same size.
      What I am thinking of doing is to replace the stator and CDI with a 90-95 one as these parts are all readily available.   Does anyone know if this has been tried before and if there are any issues with doing this.  
       As a side note I also have a 1993 Moto 4 YFM350ER that has been sitting longer but it is located about 400 miles from me at this time.  By doing this change in addition to being able to get parts I will also have 2 ATV’s that are the same electrically.
