I am dealing with an electrical anomaly of some sort with my sled. Our snow has been less than stellar so I have only ridden once but, I experienced some electrical weirdness on the way home the other night but, luckily after 10-15 minutes it decided to start and I was able to drive it home.
The sled had run fine all day and the engine pulled very hard. I was grinning in my helmet with how well it was running. I'm not sure if my issues started when I turned on the hand warmers or if it was a coincidence, but I noticed my speedometer needle swinging funny and stopping at 20 mph, 40 mph, then 60 mph, etc. I also noticed my EGT gauges fading in and out and the lights on the dash flickering. The engine seemed to stumble but, smoothed out under power.
Then after a break, it started and just slowly faded away and died. After 10-15 minutes of time had elapsed and after my wiggling of some wires down under the heat shield by the Y pipe hoping to resolve the problem, it started. I'm not sure if I moved the right wire or if something cooled enough for the sled to start working again? It fired right up like nothing had happened and I drove it 15 miles back to the truck. I left it in the covered trailer for a week and it started on the second pull and I drove it right into the shop and put it on the lift.
I inspected and added new heat tape to the injector wires under the Y pipe heat shield and put everything back together. The sled started up and ran for 20-30 seconds and then died. Now, it won't start again. It fires about every third pull but, won't start.
I read all the threads about shorted wires under the gas tank, tail light wires, TSS switches, ECUs, CCUs, checking ground wires, unplug this harness and dielectric grease connectors, etc. My issues seem to sound very much like a stator????
OK, where to start?
I think I will start with checking the electrical wires for my injectors again first. That's the only thing I messed with since driving it into the shop. I had a problem with them grounding out a few years ago and I noticed one wire felt funny, like the copper wire inside the rubber coating was broken.
The other things on my short list are the Throttle Sensor (which I unhooked a couple seasons ago because I was having issues with it). I added a tether at that time. It could be the tether or tether wiring as well....
I can't seem to find how to test the stator the ECU or the CCU in the 09 service manual. It shows a CCU test for the 600 and 1100cc sleds only. Do I even have a CCU on an 09 M8? Oh, I found the stator checks in the electrical resistance and peak voltage tests.
Please share your ideas on things I should check please.
