My nephew picked up a holder 15 end of summer. It’s all stock except a can. A few weeks ago it would not start. Dealer said it was getting water in the electric connectors so added di-grease to all major connectors. Nephew also put frog skin on the hood slots and the clutch side panel hole. Sled ran great on a weekend trip after fix, ran great Saturday then Sunday morning pulled out of trailer ran it maybe a 100 yards down the trail, temp light came on and went into limp mode. Checked coolant, full. Sled fires up but still acts like it’s in limp mode won’t come out of it. Any thoughts? Sounds like more water is in electrical? I’m not sure exactly how the temp sensor works on these, but could that be bad? Any help would be greatly appreciated.
