Run Capacitors
Voltage Test (This test is valid only if the motor is running at
normal speed and the motor start contactor is de-energized.)
Check the voltage between T3A and T3E and between T3B and
T3F at the test point strip. The voltages should be within 10% of
the sum of the line voltage and the secondary transformer
voltage. If the voltage is low, the run capacitor in that circuit is
defective. / Replace as necessary.
Current Test (This test is valid only if the motor is running at
normal speed and the motor start contactor is de-energized.)
NOTE: Only one of the two T3E and one of the two T3F
wires connected to the motor will carry a current while
running.
Check the current in T3E and T3F at the motor with an inductive
ammeter. Both currents should be 4 to 8 amps. If a current is
below 4 amps, the run capacitor in that circuit is defective. /
Replace as necessary.
