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?
