Monster580 · Nov 30, 2011

If it starts fine but won't go anywhere - then it is still in the tether cord.

With all the trouble with this that you mention - I wonder if the previous owner(s) actually USED the tether cord, and maybe it is simply worn out and not fitting tightly enough to make reliable contact?

I had this problem a couple seasons ago. Shine a flashlight in the end of your tether cord. Make sure the 'chip' is centered in there and not all mashed up or to one side or the other. Mine had started coming loose and was off to one side. Wasn't enough to make good contact. Was just about to fall out all the way.....which could also be the problem. I took the chip out and used so epoxy to get it solidly centered again and haven't had a problem since.

i do have two teathers and niether one of them works could it possibly be the post or do i have to bad teathers

When you have it running, try wiggling the tether to see if you can get it to rev over 3000. If that works, you likely just need to lightly clean the post it attaches to with a scotchbrite pad or get your tether to be snugger on the post with a ziptie. If that doesn't help, check for loose connections or rubbed/shorted wiring from the post to the DESS. If it's neither of those, you may need to get a new tether and have your DESS mapped to it. I think most Doo dealers are able to do this.

2 tethers?

Are either one of them original?

I don't think that one from another machine would work.

Are they both programed to sled? If they are not then it will only start and not rev high enough to engage clutch. Check connectors on post and where they plug in under tank cover.

yes both tethers are programed to the sled or were and i was told at my local doo dealer it was most likely the post so i replaced it and it still doesnt work
