I have a 2000 king quad 300 and had a no start problem that was preceded by intermittent instances of the bike shutting off then neutral light flickering when in neutral an then no neutral or reverse light followed by a no start condition and no lights when switched to that position. Upon investigating the regulator rectifier I found that its connector had been melted. The connector will have to be replaced and I think that it is safe to say that the regulator/rectifier is shot. Is there anything else that could have caused this connector to melt or could have also been damaged. I dont want to put a new regulator/rectifier on to have it immediately get cooked and remelt the wiring and connectors. I will try to upload a picture of the damage. I was unable to attach a pic here with the post but there is a picture in the "pictures" section of the forum. I downloaded the factory manual so I will see if I can test the generator for damage. The battery seems okay and will take a charge. Thanks to anyone that can help me determine if I have a problem with more than just the regulator/ rectifier.

you will have to put a new one on to save everything else. the regulator will maintain 12 volts, so i would say it broke down and probably just took that out, and maybe a fuse along the way ...

could have just fatigued itself ... smaell the other end of the connection, if its a burnt smell or cracked somewhere ...

looking at your pic in your profile, you might want to split that wire harness apart and look at the condition of the wires. it may have been a couple bare wires ... electrical tape will fix the covering you take apart ...

I'm hoping that is all that it is but I was worried that it could have damaged something else due to the severity of the "meltdown". here is the link to the pic.:

The fuse did not blow and another thing that was odd was that the when the switch was in the headlight position there was no current going to lo/hi dimmer switch from the ignition switch. When I took the switch off and tested it for continuity it tested okay. I also was perplexed as to why I had only about .5 volt at the auxiliary fuse on either side. The battery had over 12 volts when I tested it so I will check the continuity on that wire going to the battery next, I suppose. Are these related symptoms as well?

Yes I will definitely split and check/repair all wiring. It did look like a couple of the generator wires (there are three total) that may have made connection with one another on the main harness side. That concerned me. Could that have happened when I pull started the engine and had it running briefly?

it probably could have happened at anytime ...

      2000 Yamaha Breeze 125 slips in Forwards, runs fine in reverse
      By hengstserepair
      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.

      2000 Yamaha big bear 400 won’t start
      By Mister907
      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.
