2007 KingQuad 450 electrical issue

I know this tooic has been addressed by many, I’ve looked through many forums and pages. I did not find anything like the problem i have.

I have a 2007 Kingquad 450. I have a new fully charged battery. When i turn the key, the dash flashes and seems to struggle before getting fully lite. We can hear a small relay near the computer clicking, i think it is the fuel pump relay. When i turn off the engine kill switch and press the starting button relays click and all the power shuts off, i turn the key off, engine kill switch then start over, power is there. Atv will start with pull start, but not elextricly. if i try to use my winch, all power cuts and engine dies. 

 

Can anyone tell me what it may be? or has anyone fsced an issue like this before?

It really seems to me that you have a poor connection someplace. If the battery is fresh  then your loosing power within the harness. I would go get some dielectric  grease and start taking plugs apart and cleaning. Then add grease to the plug and reconnect. Then go to the starter relay and loosen the main battery cables on both lugs, clean and re tighten. Make sure your battery wires are not broken at the crimped part where the connector is on all ends.  Check the main ground wire. Loosen it up clean and tighten.  Lastly is it’s possible that one of your relays weather it be the main starting relay or the neutral safety relay may be bad. Both are not expensive and easy to change.  But start with your connections first.

      Well, I bought the Axis 500 sold at Lowes for $8999 a couple days ago.  This post will be about my impressions as I use, fix, and abuse the machine.  I will add to the post as I gain experience with it.
      Thanks to other posters on this site warning of new machines with loose hardware, one of my first actions was to crawl all over it checking fluids and connections.  Zirks were all freshly greased, fluids in engine, and gear boxes were up to level.  One of the little gas struts that help lift the bed to dump was dangling with only one end connected, and the other strut had not been fully tightened.
      Here are some things I don't like:
      The rear gearbox does not have a differential in it.  It is essentially a solid axle.  Tight turns on lawn will leave tracks, and turns are not as tight on pavement.  In my case this won't matter much, but if you plan to use it on a lawn, this will create tracks on turns.
      To check engine oil you need to remove both front seats and a plastic cover.  This according to the manual.  I'm pretty sure it can be checked with that stuff in place, either from under or above, but that remains to be seen.
      I am not used to a CVT transmission.  I am used to a clutch and multiple gears.  This one requires giving it plenty of gas out of the hole and then backing off to get it to shift up.  I'm sure I will get used to it, but I'd like to be able to take off quietly if I want to.
      The doors have bungie cords to act as springs to close them.  I removed the driver door so I would not need to fight the constant pressure to close.  Problem solved.  I will leave the passenger door as is.  Gotta keep the grandkids safe.
      The status display is hard to read if the sun is on it.
       
      Here is some stuff I like: 
      I was concerned about there being enough torque to slowly climb a steep hill.  There is.  I will elaborate more on this when I've had it on my steeper trails.
      The display has dedicated lights to indicate status of gear position, low oil pressure, over temp, and a bunch of other stuff.  This helps a beginner with feedback that an action taken was successful.
      The sparsity of knobs on the tires dig in well on most surfaces.  I bet they wear out fast on pavement.
      The tilt bed has a tail gate that is easy to operate.  Much like early Japan pickups.
      Steering is responsive and little slack.  Remains to be seen how long to get loose since the u-joints are operating at quite sharp angles.
      Seats are pretty nice.  Will be interesting to see how long it will take me to poke a screw driver though them.
      Seat belts are included to hold grand kids in.  Won't go over 5 mph if both aren't buckled.  Yeah, it works to buckle them empty.  Doing this leaves the belt high on back, so you don't have to sit on it. 
      Hauling it home, my trailer wheel wells were too close together to clear the tires of the UTV.  This required driving it off center a bit, with one set of tires inside the wells and one side driving over the wheel well.  Creeping over the one well required climbing a 10 inch vertical well.  The ability to lock the front axle differential kept both front wheels pulling as I drove the one side up and over the wheel well.  The guys at Lowes were impressed.  They won't touch any but an unobstructed flat trailer loading.
       
      As I gain more experience I will add to this topic,

      Was given a 1997 Bayou 220 for free that had sat in the back of a barn for almost 9 years. Owner had parked it because his kids got too big for it, and they have other bigger bikes, said when it was parked it ran fine. He gave it to me as a trade from some networking I did in his home.  
      First steps: 
      *Marvels Mystery Oil bath down the cylinder to free up the piston rings (I let sit for 24hrs) 
      *New battery as old one was shot from not having a charge for 8 years. I took my multimeter to the entire wiring harness and cleaned EVERY contact possible, as not even the headlights were working. After a few hours, everything electrical is now working. Headlights, green dash light, red reverse light (goes on and off with changing from reverse to neutral), and starter spinning strong (after a conversation with my mallet).   
      *Drained old oil (no glitter!) 2qts fresh oil with new filter. 
      *CDI was shot-- had zero spark and using a multimeter up the wiring harness everything was good up to the CDI—replaced with new one along with new plug wire and new plug now have excellent spark 
      The original carb was a total loss. I'm assuming it was parked full of fuel with the fuel switch on. It looked like they found it buried in the sand and put it on, it was so eaten and corroded my thumb went through it trying to get it apart—so new carb. I did also inspect the intake and none of what was in the carb made it into the engine, thankfully. 
      After oil bath, compression was still low—threw some brake cleaner down the intake and noticed smoke escaping from the head gasket—took the head off and saw the original head gasket was completely shot. Replaced that, and now compression is up to 90 from 50. I'm assuming, it'll need to go through a few heat cycles for the compression to really build back up (had the same issue with my 2000 Kodiak 400 from siting for 5yrs after a few heat cycles went to 180) 
      While the head was off, I did a leak test on the valves and liquid stayed, so no signs of gaps in the valves sealing. Also took a look at the piston and wall and both are in excellent shape, very clean conditions. 
      At this point, the bike should fire off or at least pop… but now that compression is back it's sucking air in though both the carb AND the exhaust pipe. Putting my hand on the pipe (no muffler) I can feel it sucking air in, doing the same with the back of the carb, I can feel it sucking air there as well. It isn't pushing air out anywhere.
      I've checked timing and it's correct. The TDC mark on the flywheel is lined up with the spot on inspection hole. The mark on the timing gear in the head is lined up with the mark on the casting there as well, so timing is spot on. I don't believe it has a leak from the exhaust valve due to the leak test I did. I also don't believe a valve is sticking, I can see them both moving just fine when looking through the inspection holes. 
      In the past, I've had a bike have intake from exhaust and exhaust going out carb, but that was the timing being off, which doesn't seem to be the issue here. 
      Any advice on this would a big help as I'm stumped on what could be causing double air intake. Chances are it might be something simple that I'm not even thinking of. 
      At this point, I'm about to order a box of hair from Amazon Prime from all the head scratching going on.
