Testing Regulating And Shunt Field Coils Radio Two Brush Generator

Testing Relay Terminal and Positive Brush Holder {see Illus. 86):

6. Touch test point "J" to "relay" terminal and test point "K" to generator frame. Ammeter should show no reading. If ammeter registers a reading, positive brush holder or "relay" terminal is grounded.

Make sure negative brush holder is tight and making good contact with frame end to insure a good ground connection.

If field coils, brush holders and generator terminals test O.K., armature must be removed and tested.
