sounds like what mine was doing a couple weeks ago. Headlight and tach didnt work and ran like crap. It turned out to be the relay like Tackbtch said. The reason mine wasnt running right is because the exhaust valves werent opening. If it is the relay you can pick one up at NAPA, here is some stuff I dug up when mine went out.
Very easy open up the left side panel of the sled and its a square looking plug with a mounting tab on the end of it, right above your secondary in the harness it just unplugs, your best bet is to go to Napa and get a couple of them, Part # AR 201 there about $12 compared to buying a skidoo one for $25.
Well you guys were right - $13.19 @ the local NAPA & we're back in business!! It was Part #AR 272 though - not AR 201. Anyway, it sure beats the s**t out of what the dealers would charge for the repair!! Thanks everybody

The AR 201 works just fine, have one in my '03 in fact (50 amp rated) but costs more. If you want an exact match to the BRP unit then get AR143 20 amp rated. The AR272 is rated in the middle at 30 amps and priced accordingly. All three will work but I would just buy the cheaper AR143 for spares
