Ok, connected Battery terms backwards on 2004 Magnum, started the quad, fan started running immediately then smoke from the front end. I turned it off, connected it correctly and quad runs now but I can't seem to get the fan to kick on so i'm thinking ECM. When i pulled apart the front end there's a black cylinder above and to the right of the ECM and one of the wires is burnt to a crisp. I chased the wire and it goes down across the engine and then enters into the engine case with about 5 other wires. The other wires don't seem to be burn but the casing is completely burnt off this one.. What did i do and can it be fixed...:-(
