I've been out of town all week so I haven't been able to do anything but when I got home tonight I did 2 quick tests. I tested the key switch with the meter and it appears to be fine. Also I cranked up the mower and when I move in one handle or the other it is disengaging the parking brake. There is a little motor I guess inside the brake actuator and when the handles are pulled in it spins and disengages the brake on both sides via 2 control arms so it seems to be working right. I'm stumped right now.
