2007 KingQuad 450 electrical issue

[Kristpj]

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.

I know this is an old post but I had the same problems this week.  All connections and wires looked good so I replaced the ignition switch with a OEM Suzuki one.  Started up and everything works fantastic!  Took 15 minutes to do it.
