This test is for the BB controller version. It does not apply to elite machines.
Let’s test for voltage at the end of the probe wires. With a multimeter you should be able to read from 3.2 to 5.4 Volts DC with the Magnet being DC- and the touch plate being DC+. If that is not present, then the wiring has a break somewhere and needs to be replaced.
