Hi everybody, need a little help with my 98' King Quad LT-F4WDX. Finally had to replace battery after 4 yrs, good for a battery I think, anyway installed new battery, turned ign switch,press starter switch and heard 1 click, no start. checked main fuse, ok. So the dreaded chapter 14,removal of fenderbody was performed. Then proceeded to run tests found out the starter relayfrom the positive side to the starterfeed side had no continuity, infinity. Ordered new relay, received and installed today turn on ign got a neutral light pushed starter button ,one click and now nothing. I had checked the neutral relay earlier and it showed good so I put it back in. Any ideas fellas? any thing will be appreciated, maybe I have to pull the starter and try field jumping it? I don't get the 1 click and then nothing, could the new relay be faulty? Before installing i performed the continuity tests recommended and it seemed fine🤔20170506_161433.jpgmower.thumb.jpg.1b8a202d126cd6cfaa1531ff13ad7519.jpg

A real common problem with those is the starter brushes. They wear out and they get stuck sometimes/often.

The starter relay has two windings to operate the plunger that closes the contacts. One set of windings earths internally in the relay, and the other set of windings earth through the starter. If the starter brushes are not making good contact the starter relay doesn't get enough power through both sets of windings to pull the plunger and close the contacts. Then you get a click.

I'd use a jumper lead straight to the starter's terminal, or, now you have the body off, straight to the starter lead going to the starter. Put another jumper to an earth and the starter motor should spin. If it doesn't spin, or if it struggles to turn, then it needs pulling out and stripping and a new set of brushes. Easy job. The new brushes come with a new mounting plate and springs and all ready to slip in.

      Hi my name is Greg and I just acquired a free 2000 yamaha kodiac 400 4x4 with the ultramatic transmission that does not run. I plan to get it going and use it around my property

      I’m brand new to 4 wheelers and just bought a 1987 Yamaha Moto 4 350. It has good compression and fuel, but no spark. I’ve looked high and low trying to find how to test all the components of the ignition system, but can’t find anything. This has a new CDI box on it, but I suspect it might be the stator. How do I test the stator on this? Any help would be greatly appreciated!

      i just picked this up. was told ran fine but overheating issues led to replacing head gasket and head. has not ran since. he is not a mechanic but helped someone else who he could not get back to finish job, got aggravated and put up for sale. i was thinking timing issues. i have 110-120psi on all 3 cylinders so i think valves are correct. dont know about distributor yet. however i have no spark. i have no power going to ignition coil. tried to follow white wire but gets lost in wire harness. does anyone have a wiring diagram? can anyone tell me what conditions have to be met before starting. motor turns over so i would think all safeties are met but you never know.

      Bought 4 wheeler for kids. Used to run and soon as it was put in gear it died. I have put new carburater, new plug and battery. The neutral light won't come on. I replaced the solenoid, then the positive battery cable and today put new relay assembly on. Still no neutral light. Not getting any juice and I don't know why.
