95. CUT‐OUT RELAY.
a. Operation of the instrument panel green signal light, indicating generator charge, is controlled by the cut‐out relay. Therefore, if relay is faulty the signal light will not operate properly, falsely indicating generator trouble. Rust around the contact points, burned points, and loss of armature spring tension are sources of most relay trouble. NOTE: Before condemning a relay because of failure of green signal light, make light test (par. [120]).
b. Correct adjustment of relay point gaps and tensioning of armature springs require use of precision electric meters and expert knowledge on the subject. A faulty relay, other than removing cover and cleaning with air, should be replaced. No adjustment of points should be attempted.
c. Remove.
(1) Disconnect the three wires from relay terminal screws.
(2) Remove the two mounting screws and lock washers. Remove relay from engine base.
d. Install.
(1) Mount relay on engine base with two screws and lock washers. Make sure that mounting is clean to make good electrical ground contact between relay and engine.
(2) Reconnect the three wire terminals to relay terminal screws. Follow wiring diagram, figure 55.
