brake switch removed, but seems ok. now what?
Silverstartech, thank you for the thorough post. THe removal was easy. Out of curiousity, I then tested the switch with an Ohm meter. I was surprised that one pair of pins is Normally CLosed, and the other is Normally Open. They then change state upon depressing the brake pedal. Meaning, it appears to me, when the brake pedal is not pressed, there is one pair of pins with connection made, and the other pair is open. Pressing the pedal swaps states.
THe table below perhaps makes it clearer:
Pedal position____ pin pair 1_____ pin pair 2
------------ _____ --------_____---------
at rest __________open_________closed
depressed _______closed _______open
QUESTION 1: IS this the expected behaviour:?
QUESTION 2: If so, why do my brake lights continue to NOT light up?
If I reconnect the switch and actuate it by hand, as if the brake pedal is doing it, I see no brake lights, in any location. My 2002 C320 manual states that the brake lights are NOT fused (this is the only circuit that isn't, for some reason). So I assumed the problem must lie with the switch, but it seems to be fine... or not?
