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?

      Just picked up an 84 LT185 ATV, I understand there was an accessory add  on that gave it electric start, anyone have any info about that kit?

      Howdy ya'll. I am working ona 2000 Yamaha Breeze 125. It was in rought shape when I received it and I am working through issues as they pop up. The quad had been sitting for years. I was able to get her running again, but I need your help with the following issue:
      I don't trust the transmission yet and I don't want to make problems any worse. So, I haven't pushed things hard at all. Low rpms, less than 5mph in reverse.

      Nuetral: Runs as expected
      Reverse: She seems to be driving fine at slow speeds. Going into reverse at idle is fine, coming out of reverse back into neutral won't work (the shifter is just stuck). As soon as I turn off the quad, I am able to shift around without any issue.
      Forward: It slips. It seems to only transfer power to the wheels on a smooth surface and going slightly downhill. When shifting into forward at idle, there is a clacking sounds during the transition. Shifting back to nuetral works just fine.

      Other Notable Symptoms: There was old oil in the vbelt and when I was tuning the carb, it starting blowing out of the CVT cooling vent at the front of the quad. Made quite a mess. There is positive crankcase pressure due to piston blowby, that I have not decided whether or not I am going to fix (customer budget dependant).  Since the oil was old, much darker than the new oil that is in the crankcase, I am thinking it seeped past a bad seal while it was sitting for years. The oil that was in it when I first got it had gas in it.

      Thoughts: I am thinking maybe there is an issue with the clutch. I worry about the old oil intermingling with the dry centrifugal clutch. I was thinking my next step would be to take the cover off of the clutch and inspect it.

      Let me know what you all think. Any advice and ideas is greatly appreciated. This is only the 3rd quad I have worked on and I have a lot to learn.

      Hi guys, I have a 2004 big bear 400. Last winter while plowing the driveway, I heard a loud pop from the left side of the engine. It continued to run as I looked for leaky fluid, but then died shortly after backing it up and won’t start now. The oil light comes on when I try to start it, no noise or anything else. 
      No blown fuses that I can find.

      Hey guys and gals. I've been working on my friends 2007 big bear IRS. Unfortunately after 3 different people got their hands on it and only made things worse every time.  After months of finding just crazy problems everywhere. I'm finally at the point we're its almost 100% !!! But I'm getting a short somewhere between the 4xW switch I believe. I managed to by searching the internet like a  fiend, got my hands on an official Yamaha wire harness for the year and make. But I don't have the numbered component list and to be honest. After hours of going through and making everything so it's  easy to reference. If anyone has a picture of the referenced components. I would be forever in your debt. I've spent hours marking up the blown up diagram so it will be easy, for any possible future repairs. Please and thank you. Here's a picture of what i have so far.  Unsealed it in plastic so oil and crap won't spill or get smudged. This damn things worth it's weight in gold.              Thanks Jeff                2007 Yamaha big bear 400 IRS.       YFM40FBW
