Default My 13 Pro 800 ain't workin' !

Started my RMK today. It seemed fine at first. I brapped it on the stand a bit and then let it warm up. I heard it idling higher and higher. Checked it out and the display was dead. I shut it off and jiggled some wires, and started it back up. Now it was low idling and it would die when I blipped the throttle. Still no display. Ran fine on a trip a month ago. Couple problems with ice in the throttle block, and I blew two belts, but otherwise it was all good.

Any ideas? I'm heading to Idaho on Monday.

Before I loaded up for the trip, I brought the sled in and cranked the heat up to 80 degrees. I found one thing that looked like a relay so I pulled that out and put it in a nice toasty spot. I think the sled dried for about 18 hours. I also drained the fuel and put fresh good stuff in.

I put dielectric grease on some connections in that bundle above the voltage regulator, and reinstalled the relay. Sled fired right up and ran great. The display worked, and showed a flashing battery icon. Also the yellow check engine light was on. These went away after a couple minutes. I stopped and started the sled a few times and everything was good. It also ran great when I put it in the trailer.

Today was the first day I rode it. At about four miles, I came to the bottom of a hill, and I looked down and my display wasn't on. It was also idling high, and would bog out if I touched the throttle. After a few minutes, it was idling crappy, but the display came back on while I was messing around under the hood, and it started running fine. Display again showed the flashing battery icon, and the yellow check engine light was on, but it ripped right up the hill and ran great. Rode about three or four more miles, and shut it down to take a leak. When I started it again, no display and a crappy idle. Died if I touched the throttle. After a bit more unsuccessful messing around, I got my first ever ride on the end of a tow rope.

Headlights are always working even when the display is dead. Handwarmers were hot when it was running decent.

Where would I find the relay, and can I test it with a multimeter?

When you get a check-engine light, hold the park brake and cycle through the display with the SET button. Should scroll through to an error code, look that up in your owners manual.

But I don't have a working display. Maybe tomorrow it will come back on? How do I check the voltage regulator?

Check for water in connectors. That's often the cause of nonfunctional displays. Harness to ECU, harness to gage.

VR's are tough to bench-test without test tools (power supply, electronic load). Easiest to replace it with a known-good. (I might have one in my box-o-parts...)

Don't be messing around with a VR like Mule stated .

There are a couple of symptoms that has been noticed when the VR is on it's way out , the gauge blacking out is very common , irrational idling , the back of the VR can also have a burn or melted spot , the starter turns over exceptionally well too .

The VR can be bad for a while and not recognizing the symptoms is not a good thing because it will damage other components .
