2004 250 with about 10 hours, ovreheating light comes on when you shift it into gear. This happens after about 10 or 15 minites of operation.

Any Ideas.

My 2001 250 did this also. What fixed it was unplugging the connector to the lights, spray some contact cleaner on the pins and plugging it back together. Hasn't happened since, so I have to assume dirt in the connector caused a short of some sort. BTW, I used my infrared temp sensor on the engine and it wasn't too hot at all, so that's why I started looking for an electrical problem.
