I have a 1996 foreman 400 I'm needing help with. I have no spark, or very little coming from the coil. I can take the spark plug cap off and crank the engine and barely feel anything with my hand. I have tested the alternator charging coil (stator), on all three yellow wires I'm getting a reading of 0.2. I have checked for continuity between all three yellow wires and ground, there is no continuity. I have pulled the plug off my regulator and checked voltage there I'm getting 14.32 volts that is with a battery charger hooked up. Charging coil line reading of 0.2 ground wire getting continuity. My ignition pulse generator is showing a reading of 337. Ignition switch is showing good. I have pulled the coil off my rancher and tried on the foreman still no fire, but tested the coil anyway and it shows good. I have a rectifier on order waiting for it to get here. I tried my rancher rectifier on it still no fire, and tried my foreman rectifier on the rancher and it started right up. I'm running out of ideas, what should I check next? Maybe the cdi box? Thanks for any help I can get

 

I got my problem figured out with some help, my cousin and one of his relatives came up today and took a cdi box from a foreman 450 and put on there. It then had spark, I put my gas tank temporarily on and it fired up without any issues.

 

Test the wires to the CDI. Sometimes CDIs just go bad but it is always best practice to check something hasn't blown it. You can blow a CDI if it has a bad earth or if the voltage reg is overcharging, more than 15v across the battery, at any revs, and the regulator is faulty.
