headlight motor limit switch
I'm sorting out some wiring problems on my 65 corvette. The limiting switch has "common" on one terminal and "norm. closed, norm. open" on the other terminal. I'm not sure which one is the ground or which is the power side to the switch. My wiring diagram doesn't tell me where the black and gray/black wires go.
Thanks Brian

On the Corvette application, I believe it only furnishes a ground for the circuit to operate, so connecting the wires as is shown by the wiring diagram, or reversing these two connections makes no difference in operation of the circuit.

That switch as stated above is not a limit switch only a tell tale light for the dash indicator. It doesn't matter which connector you connect to either side of that switch. Both of mine were not even connected when I bought the car and the headlights worked fine. The headlights are limited in travel by the "Y" stop on the inboard side of the headlight bucket shaft..

That's true as well, the limit switch is not in the headlight bucket motor circuit, it's in the warning light circuit which feeds power to the "lights" warning light in your instrument cluster.
