Reply to "The headlight motor is too hot to touch"

That pic was a great help. I managed to squeeze in and found the second lead. I think Bosswrench is still correct .. the motor is internally grounded and the two leads control the direction. The one that is "hot" in my scenario is yellow and the other one is black. I should mention that the lights are currently down.
I checked the voltage to the black lead with the battery connected and it is zero (remember, the yellow has 12V). Then I turn on the headlight switch and the headlights themselves come on (in the retracted position) which suggests that the headlight switch is OK. Also with the headlight switch on, 12V then appears on the black motor wire. Clicking the up limit switch doesn't change the 12V. Interestingly, when I checked the voltage on the "hot" yellow wire with the headlight switch on, my meter turned into a random number generator .. it could not settle on any reading. Go figure.

Maybe the important thing is that with motor wires disconnected (I don't want to operate it) I turned on the headlight switch and could not hear any relay click. I did it several times. So now I'm wondering about the relay although maybe it only works with the ignition on. So I still need to do some measurements with the ignition key in the Run position and see what happens. This is like CSI.

I apologize for this long thread but I really appreciate the input.
