Check the simple stuff first. Clean and tighten all the electrical conections. Then if still a no go, I would try to jump the solinoid to see if it is bad. If that is still a no, then I would pull the starter and either go through it or have it tested. Start easy and work to the harder more expensive stuff.

Use a pair of RUBBER HANDLED pliers to bridge the two main poles of the solenoid. If the thing cranks over, then the solenoid is bad, or the there is a problem with the low current feed that activates the solenoid.

usually if there is a bad grouund or your starter is froze or locked up it will just sit there and click. my quadrunner does the same thing and the starter was locked up so i baught a new starter and tried the electric start and it worked without clicking. try a new starter

I just finished our 1999 suzuki 300 king quad. Same exact symptoms.
Got to the starter and bench tested it with a battery charger and it worked sometimes and not others. It wouldn't work at all off of the quad battery which was fully charged.
Took the starter apart and the I think it's called an armature (The copper thing the brushes touch) was covered in grime and residue from the brushes. One brush was stuck because of the grime in it. Sand papered the armature nice with extra fine, got it all cleaned up. Blew it out with Compressed air. Didn't even have to change the brushes. And it started right up.

The segmented copper ring is called the "commutator".  The assembly  it is  part of is the  armature..   The  most common reason for a starter not  working or  working intermittently is  just as you described ..caused by fouling on the commutator  or a stuck brush not making contact.  When  a starter doesn't  spin ,  first  check to see if there   is power  at the  starter terminal when the  starter button  is  pressed /key turned.  If there is ,  then the most likely  scenario is  a  brush /  fouling  problem.  If there is no power to the  starter , then  it's time to  check the   rest of the circuit.

 Far too  many starters  have been scrapped when a  simple cleaning would have fixed the problem.  Occasionally you'll  find the commutator  badly   worn or pitted,  but usually the problem  is  a stuck brush or fouling..  Brushes wear,  so  they  could be  worn  to the point they  do  not contact properly , but they  are inexpensive and easy to  replace.

      I am unable to find a wiring diagram for this UTV.  When I turn the switch to on, the contractor does not engage.  The Brake pressure switch and the parking brake switches work correctly. What else should I be looking for?  All of the diagrams I have found are for newer models and the wire color coding is different.
       
      Thanks

      Hi all, 

      I am wondering if any of you have a Clutch Starter gear from a 1988 era quadrunner 250 sitting around that you could get me a precise measurement of the outer diameter of the race the sprag engages onto, for me? I need to machine a damaged race down and install a hardened sleeve and need that measurement (it's on a different gear than the OEM one, so I can't buy and use a OEM gear).

      Just getting into this issue really. Been replacing solenoids but now I'd like to track down the problem. This time I'm not getting neutral/reverse lights or start button. Was on a creek ride when it started doing this recently. It cranks by arcing the solenoid and gives me no light or start button but if I crank with the pull cord....the neutral light and the button work. Turn it off and try to crank with the key and nothing. I'm looking into the safety switch issue tomorrow and re charging the battery. Just figured this was odd enough of a problem that you guys might be familiar. Thanks

      Hey guys, so I've been messing with my quad, and between all the starts, the battery is dead. Is there a certain way to charge these? Can I just throw a trickle charger on it and call it a day? can i also jump it like a normal car with a battery pack or is that to much voltage
