t.o.r.s can make your M not fire at all

[89sandman]

we were up on the mountain today sitting letting our M8's idle when my buddies just up and dies, no popping, no cutting out, no warning signs at all. fired once after that for about 5-10 seconds and then would not fire again. had the tors on several cats fail before but always just got the popping and backfiring, never a totally dead sled. well it took a while to get it figured out since i did not suspect the tors could totally kill the sled. ended up have to take the throttle side controls apart and unhooking the tors sled fired first pull and ran perfect the rest of the day. just thought i'd give you guys a head up, would have been one heck of a long tow...

Dead M8

Had the same thing happen with buddies m8 on thursday, after a day of riding it just quit on the ride home. Let it sit for a bit and would run for about 15 seconds, then the next day it started up and ran find?
How do you disable or fix the TORS that you mention as it was a long tow out?

 

[jasn179]

Are you talking about the stuck throttle switch. Had mine mess up on me last year once unhooked rode all day. Hooked back up the next day ran fine since.

tors stands for throttle over ride system. when you push on the throttle the pin that holds the throttle lever to the bars makes a ground so if your throttle cable gets froze or stuck when you let off the throttle the connection is broken and it will intermittenly kill the spark to the cylinders so it will not go blazing down the trail on its own. if you take off the throttle side controls there are 2 small black connections with 2 wires each. one is for the kill switch the other is for the tors. just unplug the connection. if your throttle freezes or gets stuck the system will no longer work. the switch that goes bad is where the two wires come from in the throttle side controls.

You need at least the thickness of a credit card, in free-play at the throttle flipper or the switch will mess up. They can be a pain, like most other safety controls!

Can this switch also cut rpm's down while at full throttle. Have been chasing a problem where sled will be running at full or even partial throtle and cut back like it drops a cylinder but both cylinders firing. If you shut off and restart it may run correctly for 15 seconds and then act up. Then out of the blue it may not due it for 150 miles. I have let it run at steady throttle in this mode for over 30 seconds to check plug and pipe heat. They are equal and there is no check engine light. 2007 m1000.

arctic cat has recalled some of there ecm's on the m8. this is one of the complaints i believe. the other thing is the error code 21. but you might contact your nearest dealer and see if you fall into the serial number range for an updated ecm.

my m quit that last week by the truck.spayed windshield de icer all over the kill,throttle switch area and bingo it started.

I wish there was a better fix then unhooking it. I have had the throttle freeze open on my m7 and that switch saved my sled. Surely as many people have had this problem there has to be a fix.

can you just cut the wire that does the TORS? or will this casue problems, Ive heard of people unhooking the plug, but then you loose the kill switch too..

 

[losthelegend]

Is the tors only on the 08 m series or are they on older models, like an 05 m-7?

I was going to post this as a new topic, but since the question was asked - If someone wants to disable both the TORS and the ignition cut off, all one needs to do is pull the aluminum brace off by the steering colunm under the hood ( the triangle aluminum brack with three torx screws) and unplug the 3 wire plug ( has a brown, purple and black wire). For me, what I did because I had inadvertantly hit the kill switch many times in deep powder causing me to get stuck, is take apart the throttle block/ kill switch housing on the handle bar and removed the contact that causes the kill switch to make contact. This effectively takes the kill switch out and leaves the TORS in tact.

Don't wanna be a jacka$$ but putting a rubber band or the equivalent around the killswitch would keep a guy from hitting it accidentally.

all sleds run the tors. yes you can uhhook the tors, at least on the M8, and still have the kill switch, that is what we did. the 07 and newer M's have a rocker kill switch that the rubber band trick does not work on, it does work great on the older style controls.

 

[curt234]

Powder specials did the same thing. Looks like arctic cat never brother fixing them.

Thats the story of my life - making things more complicated than they need to be.....

what he said, but it looks like in your avatar you have an 06 so the rubber band should do.
