Clamp the earthed wire of the Power
Supply wires with a lead clip of the insu-
lation resistance tester and measure the
resistance by placing a probe on either
of the power wires. (Fig. 13)

Then measure the resistance between
the earthed wire and the other power
wires. (Fig. 13)

• Disconnect the connector of the de-

sired electric part from terminal plate,
P.C.B. Ass’y, etc. (Fig. 15)

• Similarly, disconnect the lead wires from

compressor, capacitor, etc. (Fig. 16)

• Measure the resistance in the same

manner as illustrated on the right.

Refer to Electrical Wiring Diagram.

If the probe does not enter the hole be-
cause the
hole is too narrow, use a probe with a
thinner pin.
