XP 850 does throttle switch kill spark or fuel?

Hello Polaris Community. I have looked everywhere for an answer and cannot find one so I am hoping someone can give me advice.

One afternoon I started the quad and quickly put it in reverse and backed up. I then drove about 200 ft forward and the quad died almost like the kill switch was flipped.

I did the normal spark plug change, and played with the throttle cable but nothing. I have pressure at the fuel schrader valve. The only way it will fire is by spraying fluid in the air box and it will die quickly after.

Can someone confirm whether the throttle protection switch cuts either spark or the injection signal.

Thanks in advance.

AC Outdoor Park, Seale, Alabama

Took her out to AC Outdoor Park, kinda of a boring park cause it’s small. Nevertheless I got to treat the 550 like it was built to be treated. And got to pop off a few rounds.

I went through a pretty hefty mud-hole a few times. I realized I’m more about the speed, air and the woops, I had more fun there than anywhere.

Pit riding in the iron range

hey guys. Took the 570 out for a rip in some of the old mine pits around my area. Very cool riding! That iron ore stains though. Make sure you get it off your quad right away. But here’s a pic! If anyone needs anywhere to ride up north here let me know!

Windrock Jamboree, Mar 16,17,18 – Who’s Going?

The Windrock Jamboree is this weekend, wondering who’s going.

I’m taking the Harley’s to get around on, the XMR, some RC cars and the toyhauler and truck.

Would luv to meet up with some of you and do some riding. Amy can’t ride this weekend due to her back surgery so she’ll be hanging out at the trailer w/ the dogs.

You’ll find me in the vendor area. Look for these toys and rig

!999 Sportsman 500 starting problem

I have a 1999 Sportsman 500 and a 1999 Magnum 500, both 4×4. The Magnum starts and runs fine and I use it as a base line and parts trying to figure out problem with the Sportsman.
The Sportsman will not turn over or start. Using a voltmeter and comparing results with the Magnum the problem is with the key turned on and the switch (on-off, headlight switch) in the "on" position but not pushed up to start. On the Sportsman, I’m getting a voltage reading from the cable coming from the starter motor (even when not connected to the starter solenoid) of around 2-3 violts. On the magnum it it zero. The battery, the battery terminal on the starter solenoid and the red wire going into the voltage regulator all read 13 Volts. Also I have disconnected the little red wire coming out of the starter solenoid.
I have swapped out the "on-off headlght switch", the starter solenoid and the CDI unit with the Magnum. The Magnum continues to start and run without any problems and the Sportsman contines to have the same problem.
I also notice if I disconnect either of the fittings on the "on-off, headlight switch" the voltage reading drops to zero. Headlights do not work.
Any ideas? I’m trying to avoid taking the stator out until I’m sure its not something else.
