1700 miles on my "new to me" 2009 RMK 700 Dragon 173. SLP Pipe and can, re-clutched. Lots of aftermarket vents, sled is in good shape overall...
Took it up for the season opener on Mt Adams on Sunday, 2 feet of fresh midweight powder. In comparison to the 2000 RMK 800 I rode the past 5 years, this sled handles great and the suspension and stance is awesome. It doesn’t feel quite as powerful or peppy as my old 800 but the 700 power is smooth and easy to apply. Plus I think the 163 track requires more power to turn, but keeps me afloat better. Especially after stopping or at a slower start.
so we rode about 2k up the mountain (to about 6k feet) and all of the sudden the sled died. 10 degrees and full blizzard conditions. I tried to pullstart it a few times to no avail.
I opened the hood, inspected all the fuel lines, wires (lots of them!), etc. yank a few more times and nothing. Changed sparkplugs (old one’s look fine to me), pull some more, no change. Plenty of gas. More pulls from two of us to near exhaustion, and it starts, but barely…. And I notice the gauges (rpm/temp/etc) don’t work… then white smoke
comes out from under the ecu! Engine dies before I can kill it.
Nasty electrical/plastic burnt smell. by now it's getting dark and fingers are numb, but we remove the ecu cover, all harness connections look fine. Remove the ecu and WTF?! melted hot plastic/grease coming out a small hole on the bottom side of it!
Now I know I’m screwed, and thankfully I had 4 good buddies with me. Took us 3 hours to haul/tow the sled back to the parking lot.
From what I can tell, nothing looks shorted out (outside of the ecu)… I’m no electrical expert but I know plugging in a new ECU could just fry it again…
and I'd prefer to fix this myself if possible. from what i read on this and other blogs, my voltage regulator could have failed and then without that it fries the ECU? (My old RMK lost it's voltage regulator too. it was only $40 to replace, doubt I'll be so lucky this time around
thanks for the help, I'm anxious to get back out there asap!
