My Brother Was plowing his driveway with my quad and said when every he would lift winch to raise the plow the quad would kill. on his way to pulling it into the garage it started redling so we killed it immediately i pulled the recoil it only pulls about halfway and its locked. i checked oil it was just hardly on the stick so i added more started it with the electric start it fired up instantly but just red lines. thoughts on whats wrong? what needs to be repaired? where to start?

This sounds to me like 2 different issues. Raising the plow and causing the machine to die sounds like an electrical issue. Winch or other items drawing too many amps for the stator to handle. Starting the machine and having it go to redline (I'm assuming that you mean the engine racing fast at high rpm's and wont idle down) sounds like a stuck throttle cable. Just spitballing.

I had to look up your machine as I'm not at all familiar with it. I'd say you have some serious electrical issues. Your machine is fuel injected and doesn't have a throttle cable. I bet it all stems from the winch getting hot and melting some wires.

 

[Foot0069]

I'd unhook the battery. If something shorts out in the right place it may catch 🔥.

So the thumb throttle is cableless? That machine must still have a throttle body on it, doesnt it? Wouldnt it still work the same ... throttle stuck open causes more fuel to be injected? Am I off base with that?

Some ATV throttle bodies use a throttle cable to control the opening and closing of the throttle valve. That throttle cable connects to the throttle on the handlebars then to the throttle body, and when the rider pushes on the throttle it pulls the cable, which in turn opens the throttle valve, allowing more air into the engine and increasing it’s speed/rpm.

However, some modern ATVs use (ETC) “electronic throttle control systems” that replace the traditional throttle cable with electronic sensors and motors. In these systems, the rider's throttle input is transmitted electronically to the ATV's computer, which then signals the throttle actuator to open or close the throttle valve. So whether an ATV throttle body uses a throttle cable or an ETC system all depends on the specific make and model of the ATV.

However, being a late model 700 I would highly doubt that it would have a ETC that operates the throttle valve. So a sticking throttle cable or throttle valve itself is possible in that type of system.

No I'd say you're on point. I looked up part diagrams and it seems that the throttle is fly by wire.

 

[PilotJet]

Wow ... Ok, my bad. I would have never guessed an 05 atv had fly by wire throttle. You're right, he has an electrical issue.

I’m sure most modern atvs now use ETC systems. But for the ones that don’t throttle cable issues or sticking throttle valves are a real thing, and extremely dangerous in the wrong situation.

ATV throttle valves can stick open for various reasons, which can be dangerous if the atv is in motion. A stuck-open throttle means that the engine will continue to rev up and maintain high speed even if the throttle is released, which can result in a very bad day out on trail or a engine that is excessively revving out of control. Some of the common reasons why an ATV throttle valve can stick open include the following: A damaged or worn-out throttle cable, a malfunctioning throttle position sensor, a dirty or clogged throttle body, a damaged or stuck throttle valve or linkage, or a damaged or worn-out throttle return spring.

So it’s best to inspect the throttle system for any visible signs of damage or wear. So checking the throttle cable for proper tension and lubrication and ensuring that the throttle body and valve are clean and free of debris would be the first step in troubleshooting a over revving engine.

Well, my 2020 750 King has a throttle cable that I thought connected right to the throttle body. Sorry, I must really be missing something here. Still too early in the morning for me. LOL

Clearly this is a function of a failed, early beta test of heated handlebars .

Thank you gonna look at the throttle and follow wiring for the winch! I’ll keep y’all updated!

Press the throttle. Do you hear the mechanical sound below the air box? Turning the handle bars from lock to lock can fubar the the throttle adjustment. A heavy drain on the battery with winch can cause electrical disruptions in the system. This bike is no different that my 07 700.

 

[drdunn]

I fixed it the boot on the throttle were it meets the top end popped off

Yay! Did it have a cable or wire?

 

[ajl719]

That would also do it. Glad you got it all sorted out.

Actually you have touched on a potential issue re heavy current drain. If said drain is enough to cause a drop in voltage this drop will be over the whole quad . Some ( probly all ) ecu's dont like low voltage ( called a "brown out") and will either do weird things or ......suck the kumera 😁 all together. So, all you guys with high load extras and electronic controllers need to consider battery capacity or even an aux battery for the high load thing . Maybe the winch supplier covers this in the install instructions .🙂
