Can anyone help me with this? My motorlamp is on, and I have tried different ways of turning it off. Also tried equipment at dealer. That worked until i started the engine, then it came back on at once. There is nothing, that can be related to the manual, wrong with the car: The car is in top shape. So is the exhaust. The lamp has now been on for about five months.

I am suspecting that I have melted some wires in the engineroom, and either cutted the wire in two, or also caused a short circuit. I was doing some work, and my workinglamp tipped over. I didn't take notice, but after a while, i could smell it

Could anyone tell me what kind of color the wire I shall look for/begin to check is?

Se pictures of my lamp, and the meltdown, below.
