PC / FC Fan Motor Tester
Testing a PC or FC fan motor with a multi meter is not possible, due to the electronics contained
within the motor. The simple way to test a fan motor is to apply a DC voltage with a 9 volt battery.
A test lead can be made up as shown below that will test motors fitted with either the earlier Mini
Mate-N-Lok plug or the later Molex plug.
Parts required are:
