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:
Component Qty Part Number
Mini Mate-N-Lok 2 way housing plug 1 873988
Pin Connector 2 872957
Molex Plug Male 1 881593
Socket Terminal 2 881595
Retainer Molex 1 881594
A 9 volt battery terminal connector obtainable from any electronic goods supply store.
A 9 volt battery
NOTE: When wiring the plugs, ensure that the polarity is correct, as the motors will not run if the
polarity is reversed.
