Back again with another headache, maybe you guys can help me out. 

Picked up a 87 Bayou 300 not running of course, all stator wires melted 

on the motor and also no spark. I checked the pick up coil ohmed out good. 

traced the wires and led to no cdi box, yes missing. So ordered it and while waited 

fixed the stator wires, had to wire direct to harness. Get the cdi installed and after a lot

of other things started it up. battery dead so used a batt charger to start it. Now when i shut

off the charger the motor died. So i check charging voltage...nada. I see voltage regulator is 

old and catalist leaking so i replaced it. Same thing no charge. I check stator and no voltage 

with it unpluged from harness while running. Soooooo i replace stator. Now Stator wires have

23v and up to over 50v at higher rpms. So i know its charging now. Connect everything back up and 

no charge voltage at battery! Still dies when i shut off charger. All 3 yellow stator wires have good voltage, checked

harness from stator to regulator and is good. The white wire has battery voltage at regulator, the brown wire has battery 

voltage at regulator when key on. The Black/yellow stripe has good ground. I get 3 volts at battery when i shut off charger. 

If i connect old regulator i get 7 volts when i shut off charger. Do i have a defective new regulator? Im stumped. when i 

figure this one out i have a big wiring problem on another one ill let you in on.  Az

      1989 Moto 4 YFM350ERW intermittent spark.

      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.

      I would appreciate being pointing in the correct direction for a wiring diagram and or schematics of the 88 Honda FourTrax 300 4x4 if anybody has any knowledge of how to test the ignition system stator and CDI I don't know if the voltage regulator probably and also the FCU I put a new ignition in it it is a cheap aftermarket one doesn't have the correct plugs but has the correct wiring scheme I get power  the neutral light comes on and the oil light stays on it turns over but I have no spark

      I am new to this site. I have a 1987 Suzuki LT230S Quadsport I think. Is there a difference between quadsport and quadrunner?
