Hi all. Thanks in advance. I have a 2001 Bomardier DS650. I was riding it I went threw alittle water and it stalled. No spark. Tried everything. Heres what I did. I replaced the Stator, Trigger coil, Rectifier, CDI, Battery, Coil, And Kill Switch. Still no spark. If I put my hand on the spark plug wire I can feel a very very faint spark. I have checked everything and replaced everything that can be replaced with no luck. I checked grounds, and ohm'd the new parts but cannot figure it out. I brought it to the shop and they couldnt figure it out. There is nothing left to replace what should I do..I can feel weak weak spark.

 

make sure the engine and coils are grounded to the frame.

 

What is your battery voltage while it's sitting? Starting? And running? Should be around 12.3 sitting, draw down to 9ish while starting then pick up to 14.25 while running. That's when you get it running, I just reread your question...
Are you sure you were at TDC when you replaced the stator and trigger coil? Could be off 180.
May I ask why you replaced ALL of that? Was it running fine before you got it wet? What symptoms showed up after you drained the oil? How is it turning over now?

 

It was running good till then, nothing in the oil. I think the water was jusy a coinsidence. I replaced it all trying to find the bad part. The batt voltage is 12 sitting 9 cranking and it dont start so I cant tell you that.

 

Anyone have any more ideas?

 

Well, I would recheck the trigger coil for propper setting if the gap is to much that will give you problems. If that don't work, Then buy some liquid refreshment and start at the battery and one by one disconnect every connection. check each wire carefully make sure the wire is not broken inside the insulation. get some good electrical contact cleaner and spray each connector while unpluging and pluging back in.
pay close attencion to the connector on the ecu also double check the wire that goes to the coils you will have an extra wire on one coil going for a tack signal just unhook this wire and try for spark on the frame up by the coils find a bolt hole some place and grind all the paint off just place a temporary ground wire back to the neg battery post, take the neg battery cable where it attaches to the sub frame and move it to the main frame or run a jumper cable from the main frame to the cable on the subframe I believe your problem
is a bad ground.

And remember " If the part you just paid for didn't fix your problem you now have a spare"

 

check the 2 fuses that are mounted under the brace under the seat right behind the carb there mounted to the sub frame u gota bend down to see them, they dont look like fuses but they are, i bet thats ur problem!

 

I read your post and was wondering if you checked power at the coils? Also when you said you have no spark was that at the coil or at the plug? I agree with checking the fuses first, usually the simple things that get you.
