Reverse issue, brand new Viper

[VyperNation]

Hello all, long time lurker, first time poster. Picked up a brand new pair of sleds over the weekend, and just discovered an issue with the Viper. Loaded sled in forward at the dealer yesterday. Backed it down the ramp when I got home, shifted into forward, shut the sled down and lifted it on dollies to roll it into the garage. Got a little snow tonight and wanted to take a trip around the yard with each. Rolled the sled out onto the driveway, fired it up, and let it warm up for about 5 minutes. Just before I went to take off, it started beeping and displaying reverse. I gave it a little gas and it moved forward. I shifted it multiple times. It appears to be shifting and operating just fine, but the dash and beeper thinks its in reverse. Wheeled it back into the garage, disconnected the battery for a bit (15 minutes or so), hooked it all back up, and as soon as the key turns, it displays R and starts beeping. It fires up just fine, but I don't dare take it out. Any suggestions before I schedule an appointment? Thanks for you help!

p.s. I apologize if this has been discussed before, but I only seem to be able to find issues that are stuck and won't shift. This is shifting, it just never stops thinking its in reverse.

Maybe the wiring to the sensor just behind shift actuator came un plugged?

Ok, after googling where the actuator was, I went out to the shop and checked. Everything was plugged in. So, I decided to unplug things. I unplugged the blue plug pictured (I assumed that was the sensor). No change. I then unplugged what is picutred, and the issue ceased. Obviously at that point I lost the ability to shift. The moment the plugs touched again, it started beeping, despite being in forward. I am guessing a faulty actuator?

Ok, my bad. Went out with a fresh mindset (I was admittedly a bit upset last night lol) and double checked. The beeping stopped when I unplugged the sensor, not the actuator. I will be tracking a sensor down today and swapping it out to see if that fixes the problem. If not, I will have to wait for the service appointment and figure our a way to get it there (new trailer isn't built yet). Its always something lol........

Given the fact that is brand new tell the dealer to come pick it up if he is local. Should get some priority since it has 0 miles.

Yeah any reputable dealers want to earn your businesses and go the extra mile.

So, I spent the majority of the morning trying to track down the sensor. I called up to five states away. No one has one in stock and they are on back order until sometime in March. I called the dealer, and they said get the sled to them and they would get it in as soon as I dropped it off. I had to wait until tomorrow to have access to a friends trailer (the dealer is an hour and half away, I wasn't going to ask them to come get it, nor do I think they would have). I am not the most patient of people, and decided, wait, I have a sidewinder right next to it with the same sensor, why don't I swap them to verify that is in fact the issue before I go any further with far more complicated arrangements. When I pulled the reverse actuator off the Viper, it was immediately apparent that Yamaha had pinched the wiring for the sensor behind the actuator. Bad. After straitening the wires out, I turned the key on, and boom! It was fixed. I then referenced the SW for proper routing and reassembled things. Everything works perfectly now. I have a new sensor headed my way, but now have the wiring temporarily fixed making the sled usable in the meantime. You can see in the photo below the pinched wire loom and proper routing. Now looking back on the original photo I posted, you can see how they had it smashed behind the actuator. That routing lead to my original confusion of which was the motor and which was the sensor to begin with last night. I hope no one else runs into this issue, and why is the country out of stock on this part????

Awesome and remember whoever put chaincase oil in last is who pinched the wire. Question the dealer and get part warranty either way.

Everything is on backorder this time of year....so it seems! Glad you got it figured out, I’ll be checking my wires to make sure everything is good.

Happy for you! I hate crap like that. But...and no offense to anyone, of not the dealer, then Cat pinched it, not Yamaha!!LOL!
Dam cats...!

Cat?? CAT??? What do they have to do with it

I did not realize that adding chain case oil required the removal of the shift actuator on this sled! My apologies to Yamaha for assuming it happened during assembly. I will make sure the dealer knows to watch out of that in the future.

I wrapped all the wires in foil tape. I noticed the black wire tubing the wire sits in was melted to my chain case..

Assembly was in Thief River Falls! Now, if the cylinder head fell off, well, that's a yamaha problem...lol.
