A good reminder to check your sled before you leave the dealer!

[Lorduss]

Bought my 2012 assault allmost 2 weeks ago, and damn is she pretty, allmost hate to ride her, naa maby not
Fired her up today for the 2nd time, playing around a bit just hearing how she runs, revving her up a bit, clutch engagement for the first time.
Rembered this time around to check the handwarmers, and of course they work, Hit the PERC button and nothing, hit it again holding it for a bit, let go, nothing at all.
no lights, no engine cut or nothing just purring along.
shut her off, grabbed the manual (after a bit of head scratching) and found the reverse section and nothing out of the ordinary, im coming off a 04 RMK with PERC so i didnt expect anything different here.
fired it up again and tryed a few things, that button just does not freaking work.
i rember going to the dealership and on the way reading mountainhorses thread about new sled inspection and i nailed most of it execpt for the reverse function (and hand warmers)
Now i know they test these machines before leaving the factory, i would be supprised if the PERC wasnt checked for function and it sent out to the dealer.
I assuming its something minor like a loose plug, but i cannot find the circut down below to save my life, the dealer is a little over an hour out and i dont want to find a way to lift that thing in the back of the truck again. what does it plug into? what could be wrong if my PERC wont function?
outside of a loose plug or wire its simply going back to the dealer, but if i can avoid it i would love to.

Lesson learned, inspect your machine fully before leaving.

Lorduss,
whats the idle Rpms, when your trying it.
lower elevation and the sled might idle to high to allow it to work,
have you tried it at different rpms?

 

[Murph]

Every now and again, my PERC function will fail to work. As if the button is not connected.

So far, I simply shut the sled off and restart and it "resets" itself and PERC function works fine.

Should be same elevation as you since I'm in North Lake Tahoe.

Another to check is the throttle freeplay. It should only have a slight amount of freeplay. If its excessive it wont allow reverse to work.

 

[rcbc]

my 2003 wouldnt go into reverse until it warmed up.it would die. when i brought home the 2012 it gave me some trouble aswell. I let it warm up
a bit and then switched fine.

 

[Lorduss]

im at 6,700 murph i doubt we are much different.
when im trying this my engine is warmed up and idling at 900 or so RPMS,
i have tryed revving it up a bit
i shut it off and turned it back on a few times trying, left me a bit puzzled.
engine was at 125 when trying this, the mention of throttle slack has me thinking though, even if the engine is idling that low the slight tension in the throttle could be telling the system not to function
ill try a few other things, thanks guys

should i warm her up more than 125?

 

[Murph]

125 degrees is normal operating temp on our sleds- that should be fine.

900 rpm seems low. About half of what it should be.

Pretty sure idle speed spec is 1750.

Are your lights flickering at 900 rpm?

Yep, Murph is right, 900 is to low RPM at idle. If the dealer washed the sled before delivery it is possible there is moisture in the TPS connector. I would try drying out the TPS and see if it helps. Or return it to your dealer, thats what warranty is for, right?

 

[Lorduss]

Yeah the lights are flickering, where is my tps located? I need a breakdown manual for this thing.
If drying that out doesn't work back to the dealer she gos

Edit: just rembered something, couple of days after I got it we got a surprise sprinkle on it and I had it outside without a cover at the time, I have since got it into the gerage, I also remember starting it up at the dealer and it idled at 1,800 or so, I remember it being much higher than 9. This tps sender sounds like one fix at least

 

[Lorduss]

found my way to the TPS, pain in the *** by the way.
got it off, dryed it out all day in front of a small blower. pluged in and she purrs at 1700 all day, very nice
pulled my hood foam off while i was at it, and conveniently droped one of the nuts that holds the oil res onto the chassie, into the hole of darkness under the engine, cannot find it to save my life. thats currently pissing me off but fixing my other problem is alot better.

thanks for the help guys, now i know about this pesky TPS

I have a bendable magnet the rod is soft metal about 1/8" thick and the end magnet part is about a 1/4" round on the end, you can bend it how ever you like, the sanp on, matco etc.. guys have them for about $13, very nice to have for sleds.

Or, if you have an Edge sled, yank the chaincase dipstick, wipe the gooey fuzz off of it and insert it into the convenient access hole in the side casting to fish the magnet under the engine. The access hole is under the drive clutch.

If you are fairly strong, the Pro is light enough to just clean and jerk it over your head and then just shake it a little.
