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?

The neutral light burned out and I can't find a replacement. Bought one off Ebay last year but it wasn't right one. Guy never responded when I told it was wrong.

I know it is in neutral because I can push it around. Can't do that when in gear.

I guess I'll have to get a neutral switch and start tearing brackets off to get to it.

Thanks for your response.

The light has to be on to complete the circuit even if its in neutral, you sure its the bulb, the switch is fairly easy to change on the 350 and fairly cheap, to answer your question the starter cutout relay is close to the soloenoid in the wiring harness as i recall its not easy to find on the 97 but its a small black box that plugs into the wiring harness.

My light has been out for years but it always cranked if it was in neutral.

I did find a little black box in wiring harness but I believe it only has two wires going to it. I'll double check that.

I checked the bulb with an ohmmeter and it checked as open compared to the reverse bulb.

Somebody added modified floorboards to this one which hides the neutral switch.

Thanks again for your asvice

On some of those older Yamaha's I found those relays located under the back fender, near the taillight.

Really not the greatest place to get access to but worth checking out if you're still looking.

Sorry I have not been on here for a while. Started having problems with my truck. Just put an exhaust on it. I have Drs appointments this week. Will get back on it by the weekend. Does anybody know where I can get a bulb?

      1999 Ranger 6x6 no start

      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

      1988 Yamaha 350 Big bear No spark
      By cfherrman
      Fixing for a friend. Atv was at a different friends house to be fixed and he rebuilt the carb and had it running nice, then it shut off and no more. He replaced the key and the coil.
       
      So he got busy, so I am helping, I checked the wiring from the stator to the cdi, and from the cdi to the coil. All is good. I checked resistance on the pickup coil, good, and on the source coil, open. I buy a new stator (China) and the 4 prong plug only has 3 wires in it while mine has all 4. I checked resistance in the source coil and it's in the 300's. I pulled one of the old pickup wires out of the old stator and wire it in the new one. Still no spark.
       
      Why do the wires differ, I checked the VIN again and it's "J" for the year and I got a 1988 stator. Please help!

      Looking for Quadrunner Flywheel Starter Clutch Gear race diameter
      By logray
      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).

      99 Bear tracker no neutral or reverse light or start button

      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
