c. Current Relay Capacitor Testing. T o
test the current relay capacitor, perform the
following steps:
(1) Use a standard capacitor tester and
test for capacitance.
(2) Touch the probes of the tester to the
terminals of the capacitor leads.
(3) The rated capacitance is 300 f at 150
working volts, dc.
(4) Replace the capacitor if it does not
meet the above rating
