(b) Loosen panel fastener screws (1) and open panel (2).
(c) Remove power leads from resistor, variable (19).
(d) Remove resistor mounting screws and remove resistor.
(9) Panel assembly distribution. Disassembly procedure for the Panel Assembly requires removal of
components attached to panel.
(10) Bus bar.
(a) Loosen panel fastener screw (1) and open panel (2).
(b) Remove screws, nuts and hardware from bus bar support (4).
(c) Remove nuts and washers connecting bus bar (18) from circuit breakers.
(d) Remove bus bar connector (7). Remove screw and nut attaching jumper bus bar (8) to bus bar (5)
and remove bus bar.
(11) Control Knob (Figure 2-1, item 3). Remove allen set screws and remove/replace control knob.
b. Reassembly. Reassemble components and hardware in reverse order of disassembly procedure paragraph
4-10a step 1 through 11. Refer to Figure 5-2 for wiring diagram and Table 5-2 for components and wire run list.
4-11. TEST PROCEDURE.
a. With no power and no load connected to the Battery Charging Distribution Panel, use an ohmmeter to
check front-to-back resistance of each charging station diode in each direction. If the diode fails to show a high
resistance in one direction and a lower resistance in the opposite direction, replace diode.
b. Connect a 1 ohm 750 watt resistor (load) between the red and black clips of a charging cable. With the
circuit breaker in the OFF position connect the charging cable to the top left uncontrolled charging station
receptacle. Connect 28 volt dc to the battery charging distribution panel input connector. Place the power
ON/OFF switch in the ON position to apply operating power. Set the circuit breaker associated with the
receptacle to the ON position. In 1-25 seconds, the breaker should trip. If the breaker does not trip, replace it.
Repeat the procedure for each of the uncontrolled station circuit breakers. Follow the above procedures for the
controlled station circuit breakers except that the associated resistor will have to be 2 ohms 300 watt. The circuit
breaker should trip in 0-15 seconds.
