My dad and I have been trying to get my brother's sled running for him and are having one hell of a time. There have been a number of issues that we've correct but we still can't get it going. The sled stopped running 2 years ago and has been sitting ever since.
1) The body ground and engine ground were both bad so we pulled them off, sanded down all of the surfaces and reconnected them. They are now working great as far as we can tell.
2) Once the ground was fixed, we still weren't getting power correctly so we checked the main relay and found the wire was broken. We fixed the wire with a brand new connector and some solder and that fixed the power issue.
3) Once that was fixed, we still had no spark. After testing the pick-up, we found no continuity in the pick-up so we replaced that as well (replaced pick-up with an RM Stator pick-up but maintained the factory stator). With replacing the pick-up we were able to get spark on 2 out of the 3 coils (nothing on the center coil). We already had bought a replacement coil so we threw that in and were finally able to get spark out of all 3 plugs...... sort of..
That brings us to our current state of completely out of ideas... when using the electric start, we get a quick series of solid, strong sparks (appears as just 1 or 2 sparks but I'm assuming they are very quick, multiple sparks) then nothing. The initial spark is great, but after that there is nothing at all from any of the plugs. We then thought maybe the knock sensor was bad and was sending a signal to the CDI to cut spark, but that is testing fine according to the repair manual we have (520k Ohm-ish resistance to body). We tested the stator and have continuity on all 3 white wires. We also compared the voltage output (meter on AC) against my wife's 2000 SRX which is running great (after a full carb cleaning) and the voltage is exactly the same between the 2... both in actual voltage and how quickly it gets there.
So now we are at a complete loss as to what is going on with this sled. Any help is greatly appreciated... we've been going at it for a week straight now.

simple fix..... buy a new oem yamaha stator as it comes with the pick up coil, I guarantee the problem is the junk cheap aftermarket p/u coil, they dont work and this has been a ongoing problem with that company.
I did quite a bit of research on this site and did come across that, and thought of that, but we were hoping to eliminate all possibilities before dropping another $250 on this damn thing.. lol. (which is why we went cheap in the first place... to see if that was the issue or not). What I don't get is that a pickup should be a pickup. It is just a simple magnetic coil that senses the 3-4 spots on the stator cover and produces electricity. If the stator were the issue I'd be more apt to be sure that it was the cheap aftermarket shit... but with just the pickup it's hard to tell...
But that's not saying it isn't the issue either... anything is very possible... especially with all the crap reviews I'm now seeing on this company.

ok, well you dont have to believe me but I have been thru this before.... 
The coil is very low quality and it only works once then it doesnt keep up to the flywheel because... its a cheap junk coil hence the cheap price. You know the good ol sayin, you get what you pay for, its especially true on the electronics of these yamahas.
I wish you good luck in your venture.

Trust me, it's not that I don't believe you... Im sure you are probably right... I was just hoping to maybe get a few suggestions on things to try / test that don't require $250 before I just threw more money at it. I guess you could call it denial.. lol. I may just say screw it and pick up the OEM stator and hope for the best.
On a side note, has anyone had any luck sourcing just the pickup? It's completely stupid on yamaha's part because that pickup is completely separate from the stator minus the rubber boot... there should be no reason it isn't available separately... I was hoping to find some numbers on it to try going directly to the source (since I doubt Yamaha makes the actual pickup) but its 100% blank of any numbers or information.
Go thru the classified section and look for the parts you need to save a few bucks on genuine Yamaha parts.
