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

Double  check  wiring.. In many DC  circuits  with multiple  wires at a connector white  is  ground.  The  black/ yellow  and  white might  be  swapped..   Only a guess since  I  don't have access to  a wiring diagram  for your  quad.

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

      I have a 1997 Yamaha Big Bear 350 4x4. It used to start right up. Then all of a sudden it wouldn't crank. I have a schematic for it so I started tracing the problem. I had no power at the starter solenoid. According to the schematic the power comes from the neutral switch and through the starter circuit cut out relay. I cannot locate the cut out relay on this machine.. If I apply power to the relay it will crank with the start button.
      The neutral switch is hard to get to with all the brackets on this thing. I did find out from all my research that if I apply the rear brake lever it will start.
      Does anybody know if the cut out relay exists and where it might be found?

      hi everybody
       
      I have a kymco mxu 250 automatic from 2006 250 cc  that keeps going forwards or backwards when i shift backwards or forwards an then shift to neutral .
      if i shutdown the motor and push the quad and restart then its in neutral and don't go forwards or backwards, i already checkt if my motor is running good stationairy .
       
      what can it be or what can i do to fix this?
      thanx in advance
      p.s. Sorry for my bad english it's not my first language.
