TESTING CAPACITOR RESISTANCE
2. Set an ohmmeter on its highest ohm scale and connect
the leads to the capacitor -
A. Good Condition - indicator swings to zero and slowly
returns to infinity. (Start capacitor with bleed resistor will
not return to infinity. It will still read the resistance of the
resistor).
B. Shorted - indicator swings to zero and stops there -
replace.
C. Open - no reading - replace. (Start capacitor would
read resistor resistance.)
S-15B CAPACITANCE CHECK
Using a hookup as shown below, take the amperage and
voltage readings and use them in the formula:
Capacitance (MFD) = 2650 X Amperage

WARNING
Discharge capacitor through a 20 to 30 OHM
resistor before handling.

TESTING CAPACITANCE
capacitor.capacitor out of the circuit once the motor comes
up to speed. This type of relay is position sensitive. The
normally closed contacts are wired in series with the start
capacitor and the relay holding coil is wired parallel with the
start winding. As the motor starts and comes up to speed,
the increase in voltage across the start winding will energize
the start relay holding coil and open the contacts to the start
capacitor.
Two quick ways to test a capacitor are a resistance and a
capacitance check.

HIGH VOLTAGE!
Disconnect ALL power before servicing
or installing. Multiple power sources
may be present. Failure to do so may
cause property damage, personal injury
or death.
1. Discharge capacitor and remove wire leads.
Discharge capacitor through a 20 to 30 OHM
