http://www.electronicrepairguide.com/mosfet-testing.html WebWith a multimeter, we will check the voltage between the wire coming from one hall sensor and the ground. We will repeat the whole procedure for the two other hall sensors. Some crocodile clips may be handy as well as thin solid core wires. Set your multimeter to low voltage range (ex. 10V) as the readout will be rather low.
