vibration, heavy arcing, and burning. Polarize the generator by disconnecting the field lead at the regulator and
momentarily connecting a jumper lead between the generator field terminal and the regulator battery terminal.
Remove the jumper lead and connect field lead to the generator (3, fig. 33).
d. Test and Adjustment.
(1) Mechanical adjustment.
(a) Disconnect regulator-to-battery cable.
(b) Remove regulator cover as instructed on figure 32.
(c) Press down on the cutout relay armature (1, fig. 33) until the contact points are barely touching. Measure the
air gap between the coil core and the armature. The correct air gap for the cutout relay is 0.048 inch.
Note. Do not measure the cutout relay air gap between the brass residual pin in the coil and the armature.
(d) Should the cutout relay air gap not be as specified, bend the armature stop up or down to obtain the proper
clearance.
Caution: Make certain the cutout relay contact bracket is in proper position to allow both contact
points to close simultaneously.
(e) Measure the clearance between the contact points. The proper cutout relay point opening is 0.035 inch.
(f) If the cutout relay point opening is not as specified, loosen the two
