I am at my wits end. I cannot get any spark at the plug. I replaced everything. New loom, CDI, Ignition Coil, Regulator, Stator.
To attempt to eliminate kill switch issues, the only connections I am working with are the Stator to CDI, CDI to Coil., Starter solinoid to battery. The regulator is not connected, nor are any switches or other plugs. I have even removed the kill wire from the CDI connector. So I have the bare minimum of a ignition circuit. Yes, I do have a battery connected and earthed to the chassis.
I am getting around 20v AC out of the stator on the red/black, and 0.5v AC on the blue/white (trigger). Same voltages at the CDI connector (input)
I am only getting around 0.5v on the yellow/black out of the CDI to the coil.
I am getting around 0.5v AC at the sparkplug.
Any suggestions?

      TRX300 No spark

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

      2004 DVX 400 fuel issues
      By HeWasRidinDirty
      I rebuilt the carb on said machine. When I hook up the auxiliary gas tank it runs fine and everything is cool. When I put the fuel tank on and hooked up the lines, it completely flooded the cylinder and even about an inch of fuel in the air box. I'm pretty sure that it comes from the little hose on the petcock and hooks to the top of the carb. WTH is that even for? I mean the thing runs fine on the auxiliary tank, so idk And on the petcock when it's in the "on" position, I get no fuel. The petcock from the bike I took it apart and checked out how it operates. The sharpie marks indicate how it really works. Now the other petcock w/o the sharpie marks is an old one that was leaking that I removed from a Polaris quad. It's exactly the same thing, except the small hose and nipple have been removed. I'm so confused, LOL

      2002 Polaris 400 Sportsman Shift Indicator Issues
      By jeffrocdx
      I'm working on a 2002 Polaris Sportsman 400 with shift indicator problems. The indicator panel only will show Neutral and Reverse. If it's in High or Low, the indicator will show "R".
      I have replaced the three position indicator switch on the transmission. There is also a two position switch on the tranny that I didn't replace. If anyone is familiar with this problem, please let me know what I need to do. Any help is greatly appreciated!

      Kawasaki Bayou no spark
      By Guest
      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...
