BREAKING NEWS! Today I stripped off 1/4" of insulation from each brake wire at the brakes then had DW do the lever squeeze then brake pedal (about a 8 second or so lag) and had voltage at each. Taped the wires up, then jacked up each wheel in turn, and had wife repeat process as I spun the tires, and I've got brakes! I think I probably had a compromised connection at the plug/receptacle, and probably fixed it when I sanded them. I was trying to "feel" the magnets energize with my hands instead of doing it with the meter. Lesson learned. Thanks for all the comments!
