2008 Suzuki King Quad Voltage Regulator shot?

Recommended Posts

My battery on my Kingquad was low, but not dead, so I hooked it up to my 2A charger. The problem is that I left the key turned on. After a couple of hours, I came back to check on it. I disconnected the charger, and tried to start the quad. Nothing happened. The display did not come on, nor did any indicator lights. After a few seconds, the display came on, but it had a "chec" message displayed near the odometer spot. And something was clicking under the seat. It is what ever the electrical component is right next to the fuse box. When I depressed the brake, to start, the display went black again.

I check all the fuse, and they looked good. Also, the battery is fully charged. I think maybe I burned up the voltage regulator. Is there a way to display a diagnostic code? Any other ideas?

Not familiar with the quad but check to see if you have any fusible links of any kind, dirty grounds etc. start with the easiest. you might also have a burnt up battery. A battery might show 12v but wont have the amperage to start/power up the quad. If you have a known good battery try that or another atv you can check that battery with, that will help eliminate changing parts and wasting $$.

Thanks for the advice. It was a burnt battery. Apparently there was enough of a charge to look like 12 v, but as soon as I depressed the brake to start the quad, the rear light dragged it down to dead. New battery, and everything is good.

I was going to say, sounds like a bad battery and that was your starter solenoid clicking or fuel pump/ignition relay. This is 2005 or newer machine? I used to own a 2005 King Quad 700.

Yeah, its a 2008. It was a relay of some sort clicking. What made it weird is that I had accidentally left it on the charger with the ignition on. When I discovered my error a few hours later, it seemed like the battery should be happy, and something else causing the problem. A new battery is easy to replace, so I consider myself lucky.

      posted a while back - it was running at one point - I have all the plastic shroud off - it's down to frame and engine now
      -fuel pump: when line from petcock is attached, no fuel comes out other side to carb; the line to the carb is open (can blow through it); I thought when I cranked engine that the pump would spit out fuel on other side but it does not; I removed fuel pump and opened it up - diaphragm looks good - but internal areas had lotsa calcification build up - I cleaned this out and dried it good - the clear plastic pieces (?diaphragms) aren't broken - the spring w/ steel ball on end moves freely; am putting it back on tomorrow; but can anyone answer about the pump? isn't it supposed to pump fuel through it... to other side... to carb? puzzling
      -along with fuel pump: I replaced petcock 3 weeks ago (gas tank had rusty fuel in bottom - cleaned it out prior to new petcock); when I turn petcock arrow NOT to on or reserve, fuel comes out of line; when I turn it to on or reserve, fuel doesn't come out; puzzling
      -I don't know what's on back of fuel pump - it's a valve that has a hose coming out of it - looks like it goes to engine/carb - I haven't traced this out yet - what is it?
      -can squirt gas on air filter and engine will run for 2-3 seconds then stop - fuel in top of carb (under diaphragm) does same
      -it likely needs carb rebuild - will get to this - but something isn't allowing fuel to get from fuel pump to carb
      -I THINK it has a mikuni model x carb - diaphragm is ID 26mm  OD 68mm - hard to find inexpensive diaphragm, I guess because it's a model x
      -last thing - I replaced solenoid due to old one clicking; I HAVE to be charging the battery or it won't start/turn over - battery just goes dead; but if charging, it'll turn over nicely; i'm guessing it's a bad battery
      -any help appreciated - I've never owned an ATV before - inherited this beast from grandparent in-law

      First time using this forum.  Owned a Kawasaki dirt bike once, had no issues.  But I picked up this 4 wheeler at an auction.  They stated it ran, but only needed a battery.  Well I do not believe that was all true.

      Some pictures are attached.  Not sure why, but the whole air filter stuff was removed.  They had some small thing inserted as a make shift air filter.

      I purchased a battery to try this all out.  Waiting to return it and get the proper size, as it was too big for the battery box.  But here is my issue I had while the battery was connected.

      1 - The lights on the steering column did not come on.  Not sure if they work or not.

      2 - The starter solenoid seems to be bad.  I have a new one on order. 

      3 - In the pick, there is another rusted part.  Not sure what that part is or what it is used for.

      4 - What is the 12v rectifier?  square bodied part.

      So when I hooked the battery up.  Pushing the start button did nothing.  Pulling the cord to try and pull start, it turned, but would never fire.  I have put in a new spark plug as well, it looked worn out.  With electric start, I crossed over the posts on the start solenoid, it turned over, but would never fire and start.

      I have read a few other threads and it stated something about needed the neutral light on.  SOmething about a kill switch.

      Any help would be appreciated.
