My 95 850T started with door open chiming and foot well light staying on, so I opened the door up Saturday to see what's up with the microswitchs. There are three wires to it: yellow w/ red, white w/ black, and solid black (ground). I hooked up a VOM to the wires and tested both open and closed latch. With latch open there is connectivity between all 3 wires. With latch closed, infinite resistance between each of the three.

1) Is this normal functioning of the two microswitches ?
2) I would have anticipated that the black ground wire to have connectivity with the other 2 power leads, but why are those 2 other wires showing connectivity ?

TIA, Al
