Make sure the tether (DESS) is plugged all the way in first.

mopar01 · 01-18-2006, 07:01 PM

yea its plugged in and if u realllly pull it the light barely i mean very slightly lights up but still no spark.

mopar01 · 01-18-2006, 07:02 PM

and yes the kill switch it up too so thats not the problem

**smallengineguy** · 01-18-2006, 07:25 PM

unplug them (key and kill) that will eliminate them as a cause.

mopar01 · 01-18-2006, 08:52 PM

already did that
both are bypassed
i heard it could have a stator problem or the computer or a coil

**smallengineguy** · 01-18-2006, 08:55 PM

Coil, CDI or stator.

mopar01 · 01-19-2006, 05:01 PM

so what should i do first i mean this sucks it was not even a day old and it **** the bed is that just bad luck or is this going to happen again is their any way of knowing which it is because they are all EXPENSIVE i just spent 3000 on the sled and it now dosent run should i sell it or fix it i mean i bought it to hopefully not have problems but searching the net seems that alot of people have this problem with them if there is a way to test these parts if you could please explain how if you can thanks!

**smallengineguy** · 01-19-2006, 08:34 PM

DOes it have one coil or 2? If it has 2, what are the odds that BOTh are bad at the same time??? Minimal. That leaves the CDI or stator. I'm willing to gamble it's the CDI. Look for one on eBay or an aftermarket, they're cheaper. Maybe you know someone you can swap the CDI with to try?

mopar01 · 01-19-2006, 09:15 PM

ok it only has one coil and im checkin around for a CDI is the CDI the thing that is sitting on top of the oil tank its got alot of wires to it and it looks like a computer module?

**smallengineguy** · 01-20-2006, 05:49 AM

Yeah, black thing, usually with 2 plugs on it.

the easiest and cheapest way to find out what quit , as much as your going to hate hearing this, is to take it to a dealer and have them doo diagositic scan on the system, with dess and the mpem
electronics it could be anything and each componant is not cheap
i am thinkin it might be your stator but paying for a scan is cheaper than replacing parts till you find the culprit. i to own a '01 800 and it has been troublefree for over 4000 miles but they are noted for stator problems. i have a complete service manual for this sled and you would need special tools to do any indepth testing the electrical system. good luck!!!

01MXZ800 · 01-21-2006, 08:50 PM

P.S. if the sled is equipped with DESS there is no way to override the system, the teather and the kill switch HAS to be hooked up or it will not run. it is a anti theft device, your problem might be the teather itself for it has a chip that has to be programmed for
that sled for the sled to start. if the chip went bad then you need to get a replacement programmed that is why i suggested taking to dealer for the scan.

mopar01 · 01-22-2006, 07:58 PM

ok thank you i will try that but if anyone can think of anything else or any other problems i might have with owning this sled please let me know thanks

i have a 1999 rmk xcr 800 triple i replace bottom end new piston jug got the statter rebuilt put all togeather got spark in no 1 and no 3 the middle one does not fire the coil all all good can it be the bottom end please help

**smallengineguy** · 11-03-2012, 01:29 PM

No. If one and three are firing, it must be the coil or plug boot.
