Set the ohmmeter to the R x 1 scale.
To test the compressor windings:
a) Touch one of the ohmmeter test leads
to the Common (C) pin, and the other
lead to the Start (S) pin. The meter
should indicate between 8 and 11 Ω.
b) Touch one of the ohmmeter test leads
to the Common (C) pin, and the other
lead to the Run (M) pin. The meter
should indicate between 2 and 3 Ω.
To test the overload, touch the ohmme-
ter test leads to the terminals. The meter
should indicate a closed circuit (0 Ω).
Terminals
To test the relay, touch the ohmmeter
