Hey guys and gals im a noob to the posts so please bear with me. I have been having trouble with my twin running on one cylinder after going through a big mud or water hole. I changed the plugs and wires. I think it is an electrical/ moisture problem. I was told by the dealership it was most likely the wires but it did the same thing with the new wires on. Maybe Coil? Any suggestions would be greatly appreciated.

 

Sounds like a coil issue.

 

Do you think a guy could get away with spraying the coil with electrical sealant or am I gonna have to spring for a new coil?

 

Go get some di-electric grease and put a quite a bit in each plug wire boot , should stop your problem, mine did the same thing.

 

 

Thanks for the tips guys. Just an F.Y.I. I found out that the coil had a tiny spot on the back where it was grounding out against the frame. When the water splashed up it would act as a conductor between the 2. Weird and probably a very rare problem but I hope that is it. I also filled the wires with the grease which was also a very good idea. Thanks again.

 

I had the same exact problem on my '06 SP800 yesterday, the very first puddle I dropped a cylnder and turned right around. Sad! I'm gonna have to take my coil off the machine and inspect it closely. Just d-greasing the plug boots at the coil did nothing sadly. I'll report back. Erik

 

Fix the rubbing problem first, silicon the woren area of coil and then use the electricial spray and on every wire connection you can see on the entire ATV.

 

When I pulled the wires from my coil and let them dangle, a fair amount of water poured out of the wire loom that surrounds the wires. Do you think I could have a cracked wire and the water getting in there is my culprit? Thanks, Erik

 

Those coil wires are pretty heavy and hard to crack, Your talking about the round black plastic tubing the wires fish through? if so they will hold water no matter what they just defend againds rubbing wear aginst the frame.

Concentrate on the wire end connections only and see if that works first,before a bad spot in between which would be a long fustrating track down for sure.
