'98 KQ 300 - Dead short at 20 amp fuse.

Recommended Posts

 

So I fired up the quad the other day and let it idle for about 5-10 minutes and it ran great then died.

 

I go to check it. No lights on dash, nothing.

 

Check the main fuse and it's blown. Key's off/out. Put in another and it blows immediately.

Pull out the meter and see that on the non-load side of the fuse holder there's continuity to ground.

Check all obvious things. Wiring diagram. Connectors. Frayed wires. Bad grounds.

battery measures ok at 12.8v.

I'm dreading taking off the front plastics but I suspect the regulator/rectifier. The wiring diagram shows the red wire (the suspect wire) goes to the ignition switch and the regulator/rectifier.

Anyone else experience something similar and/or have any troubleshooting tips that may save me the grief of removing the plastics?

 

Thanks much,

 

Warren

Ripped into it today.

 

Looks like it's the rectifier for certain.

Burnt at the connector and disconnecting it eliminated continuity between red and black wiring at battery.

 

Any good sources for a decent replacement?

Also, do rectifiers just die like that or is there anything else I should check?

 

Thanks!

The main reason I’ve experienced in rectifiers going bad is heat! Some people paint them while cleaning up and painting a bike.  Also a lot of them are located close to the exhaust and in a place where air flow is limited.   The diode inside is the first thing to go and that causes a back flow of current. 

So it may just be that.

      From Arkansas. Just bought a 2012 Gator 850i RSX because I could not pass up the price. BUT it has an idle problem. So, to be honest, I joined just to get a service manual. I have a choice: 1)Buy a hard copy: ~$100; 2)Buy a CD ~$35.00; Get a direct download for free posting 10 times; or get a download for $29.00 (subscription). Haven't decided what to do yet.

      Howdy y'all, I'm trying to fix a neighbors 2015 Brute Force 300. Came in with hard to start and won't idle except on choke issue. I pulled the carb and found the pilot jet as well as the emulsion tube partially clogged. Cleaned up everything, put it back together, still having issues...  It will start right up on choke and will also start off choke if you give it just a touch of throttle but it absolutely will not idle unless it's choked just a touch. Also, excuse my ignorance but I'm assuming the "dial" thingy attached to the carb that turns in and out is for setting idle??

      Bucking started about a month ago and works ok after 1/2 hour warmup.  Today while working on it i discovered that if i put the ignition switch in LIGHT position it runs fine right from the start.
      I'm stumped!  Any idea why this could be?

      This is something I'm extremely curious about. Has anyone ever attempted to buy a quad (or any other vehicle) from an impound lot? I've always wondered if this could be a bargain, or a waste of time. Google searches do turn up some helpful results. Looks like the state of NJ holds auctions online which I'd be a bit hesitant about.
       
      My online searches haven't really turned up any results of anyone buying an ATV this way. I'd be really curious if anyone tried this, or knows someone who has. I've actually found a couple pages with online auctions for my state, but none had ATVs.

      Hi, I have been around everything with a motor since I was little, and finally purchased more to get my husband, and kids involved. I have 4 quads I will be searching around for information on. I have two 2002 Suzuki LT80K quads, a 1997 Yamaha Timberwolf 250, and a 1996 Kawasaki Bayou 220. I have had different ones throughout the years, and plan on buying another Yamaha Banshee. I plan on trying to learn more about all of them, so I can customize some of them. I know nothing about them besides how to race them, my dad always took care of the rest, but figured it was time for me to learn.
