Ghost in the Machine: 2004 Sportsman Powers on randomly without key
2004.5 Sportsman 500 H.O. 4x4 Has been turning itself on and off randomly. Speedo will light up/turn on and rear brake light comes on.
I have replaced the ECM with the updated version due to fan running constantly, fixed that. Replaced the hall effect sensor due to speedo needle not moving.
Thought I had everything fixed, but then the speedo started to turn on/light up randomly without the key in or ignition turned on.
Mechanic said the Speedo was probably the issue, so replaced it with a new unit and everything seemed fine, but tonight after plowing, it started doing it again. Don't even need to have the key in it!
I have no idea where to go from here, unless some else has experienced this problem. Any ideas before I take it to the stealer?
