(8) to full clockwise position. Multimeter reading should be approximately 0 ohms. Turn
REACTIVE CURRENT ADJUST rheostat slowly to full counterclockwise position, and observe
multimeter. Multimeter reading should evenly increase up to between 4.5 and 5.5 ohms.
(8)
Connect multimeter to wires 236B and 236C, and turn REACTIVE CURRENT ADJUST rheostat
(8) to full clockwise position. Multimeter reading should be between 4.5 and 5.5 ohms. Turn
REACTIVE CURRENT ADJUST rheostat slowly to full counterclockwise position, and observe
multimeter. Multimeter reading should evenly decrease to approximately 0 ohms.
(9)
If multimeter readings are other than above, replace REACTIVE CURRENT ADJUST rheostat (8).
