a. On-Equipment Testing. Before removing the
blower motor assembly, peform an on-equipment
test to determine if removal is necessary. Test the
motor for resistance with a multimeter set on the
ohm scale as follows:
(1) Touch the multimeter leads to the pins
in the receptacle connector. The 400 Hertz motor
assembly should indicate about 2.25 ohms. The
50/60 Hertz motor assembly should indicate about
4.7 ohms.
(2) Connect one multimeter lead to the
motor assembly frame. Connect the other lead to
any of the three receptacle pins; no continuity
should exist (O reading).
