Bottom of a canyon, starts, but wont move. Believe its the throttle switch.

[Dpoole]

Landed myself a pretty significant barrel role. Upon landing and inspection. I found a list of broke parts.

Throttle Block completely shattered.
Grip in a knot
Handle bar hook no where to be found.
Thumb warmer cabling destroyed.
Hand warmer cabling destroyed.
And what I believe to be the throttle switch destroyed.

The sled starts right up, but bogs if I try and provide it with throttle. I believe it to be the Throttle switch. Does that sound right? Would that cause something of this nature?

It appears to be two wires that ultimately mount within the stock throttle block.

Any experience or knowledge of that switches functionality would be great. Thank you!

I am also open to the idea of an aftermarket throttle block.

Mine did the same thing after unloading it at Tog. Apply any throttle it would just cut out and die. But it started up and idled fine. It WAS the throttle safety switch. I removed it from the side of the throttle block, cut the tape apart, and removed the plunger and the spring (and possibly a little tiny electrical piece, can't remember off the top of my head) and reinstalled the gutted switch into the throttle block. Good as new, keep on mind if you're throttle sticks though you're on your own and id hope you have a tether.

TSS By-Pass

There is a good post on SnoWest with a way to install a resistor to defeat the TSS safety switch. Need a tether though.


Bought mine from LoudHandle on the site.

Definitely sounds like throttle safety switch to me..

 

[AKFULLTHROTTLE]

Yep.. TSS for sure.

MY TSS Bypass Jumper thread for your information / education

Carrying one of my TSS Bypass Jumpers will help ensure this does not mean a tow out, a chopper flight, or leaving the sled for days while you scare up more parts.

I'm still curious as to why you need a bypass jumper. I just removed the parts inside mine and have done the same on a handful of sleds. No issues...

Its very easy to do.

It is an option for those that what it, TSS Bypass Jumper

I started building them, because I don't run the stock throttle block. I run a modified Polaris Billet Race Sled Throttle Assembly.

Enough people were having issues with them that it became a sought after item so I started producing them.

So It is an option for those that what them.

If you prefer your way, so be it. But it can still fail and leave you in the bush even though you've taken it out of the throttle block. FWIW

My TSS is still inside my throttle block, I just gutted the parts inside of the switch itself and put the empty TSS back into the throttle block.

PM me a price for your gadget if you would. I'd like to have the knowledge to not only replace, but alter, and or trick if need be. It is indeed in the bottom of a very undesirable location, and it has been snowing ever since I left it. I'd imagine my Saturday is going to be an adventure.

 

[XFIRE800]

What exactly does the tss do? Certainly doesnt help me when my throttle freezes open.

 

[Reg2view]

Kills the sled if the throttle bodies are opened (as in iced/sticking/frozen) without the throttle itself being opened (must be fully closed, of course). It's not for a stuck thumb throttle, but for iced throttle bodies.

Its a little annoying sometimes dealing with stuff like this, but I was test riding a sled around the field and the throttle body bound up (corrosion) WOT. glad it shut the sled off instead of going 100mph into the barbed wire. Pretty easy and cheat it to fix and get out.

This is why we use a Tether...

i had an issue 2 times yesterday.
cold temps, blower powder, and some sun.
after stopping, and taking a break, there were 2 times when I would go to give the sled throttle and it would bog just as the clutches were engaging. blip the throttle a couple times and jimmy the flapper where the pin was and it would be fine.
i think there was a little ice build up at the pin and not allowing full movement of the the flapper back against the block.

does this sound like the TSS doing its job because it thinks there is an issue (possibly due to ice buildup)?

If so, I need to bypass.

Not really, it was an issue with ice buildup in the TSS throttle switch itself, but you figured it out and cleared it. Common issue. With a perfectly designed switch, the throttle switch itself would never ice up. But the not so smart ECU just saw that the TPS change without the throttle switch opening, and kicked in. The TSS exists as an escape hatch for a stuck/iced throttle body (see Wheel House's post, that was a perfect example).

it sounds like it's working. blow on the ice and remove by hand. it happens and does ice up in certain conditions, usually in deep snow with the warmers on for a while. after i shut it off, the block is warm and melting snow that then freezes on a break. not too big of a deal if you can clear the icing.

yep, it was blower snow, face shots all day.
cold high of 20* so hand warmers were on high all day.

thanks
