2020 died. No spark.

[darklightning8]

Sled was running flawlessly when it died like I hit the kill switch. Long story short - no spark. Swapped out the coils with another 2020 and still nothing. Headlight lights up when pulling the rope (does this rule out the stator?).

Sled is in a really bad spot. Left it and rode out doubles. Really don’t think I’ll be able to tow it out.

Going back in tomorrow. Hoping it’s the TSS but I’m wondering what else I can check. I put dielectric grease on almost all of the connections when I got the sled. Only 350 miles and has run flawlessly to this point. Didn’t show any signs before it died. Just 100 to 0 like I hit the kill switch. Any tips/advice greatly appreciated!

The light trying to light up tells you the lighting coils is good not the complete stator. I would start by,
Checking fuses / relays
Unplug the TSS
Unplug the tether
Unplug the kill switch
Unplug the key you can do this with the main harness for the hood
Check the timing sensors connectors
Check all connections you put dielectric grease on to make sure they didn't come apart
I can't think of anything else you can do, Fuel level and new plugs????
Good luck

Where are the timing sensors located?

There is two plugs coming out of the stator one on each side

I would check the voltage regulator as well.

Never done that. Could you explain the easiest method? Thank you.

I would just buy one and take it with you to swap out. I don't have a ctec, but mine went out on my 15 800. Just trying to offer ideas to help.

That regulator is more expensive than I thought. $160....maybe borrow a known good one to try. Have you reached out to your dealer? I would so that you can have a plan when you go back to try and get it running. Never fun having to do this stuff in the backcountry, but it is better than leaving your sled until it can be recovered obviously. I hope you get it figured out and please post the solution when you get it figured out.

first guess would be kill switch https://www.snowest.com/forum/threads/2019-alpha-no-start-kill-switch-fix.446439/

Not the TSS, will start and idle when that fails, only comes into play above idle

Did you find the problem?

Did you find the problem?

I did not. Ruled out the tether, ignition switch, kill switch, and TPS. Tried towing it out with no luck at all. I had to go back to work so it’s gonna sit there for a week or so...

Just found one where the kill switch wires at connector on clutch side were laying on exh pipe and shorted out.
Also had one sitting in enclosed trailer with heat off- lots of moisture and and frozen in there. Drug sled into wood heated shop near stove and fired up after 20min, so not sure where fault was or if it was moisture/ice.

I also noticed the handlebar wires were close to the pipe on my sled. I re-routed them before the first ride. Don’t think that’s my issue but I’m sure it’s a common problem. Not sure if that’s a factory issue or dealer setup?

 

[slyrydr]

my dealer had me bring sled in due to wires maybe laying on pipe as "kgra" stated...don't know if it was cat recall or dealer having other sleds with the problem....dealer said it was cautionary due to set-up problem..

Did you ever figure this one out?

I found on mine that a one set of wires had slipped out of the front of the Velcro cover behind the muffler and was rubbing through one of the yellow wires and a black wire. Believe they are ignition related if I remember right. Was the harness with two yellows and a black. The wires were bare but the metal was still painted so wasn’t grounding and had no drivability issues. Something to look for

Did you figure it out? I’m having same issue
