ohms indicating that the relay contacts are closed. If relay does not close,
either an open coil or open polarity diode is indicated and the relay assembly
should be replaced. If this test indicates that the relay is okay, the polarity
diode should be checked by connecting the positive battery lead to male pin C and
the negative lead to male pin F. The relay should not close; if the relay closes,
the polarity diode is shorted and the relay assembly should be replaced.
b. Socket assemblies. Sockets should be checked for signs of buring,
arcing, or broken connectors. When replacing sockets, be sure that the leads are
in their correct location and secure solder Joints are made. Always use new
gaskets when sockets are replaced.
c. Feed-through capacitor. Remove the shield plate which covers the
capacitor assembly. Remove feed-through capacitor assembly by disconnecting leads
and removing socket-head bolt which secures assembly in the case. Check for
continuity is not obtained, replace assembly. Capacity may be checked by
connecting a capacitor tester between the terminal stud and outer housing.
