BATTERY CHARGING OPERATION (Lead-acid, 12-volts dc).

TM5-6130-301-13&P

c . Select one of the. battery charging cables (Figure 1-2) for use on connecting battery to distribution panel.

d. Connect red alligator clip on end of battery charging cable to positive (+) battery terminal, and then

connect the black alligator clip to negative (-) battery terminal.

e. Insert polarized connector of battery charging cable into the selected polarized receptacle connector and

twist connector clockwise to securely lock in position.

NOTE

If the distribution panel is not already in service, it will be necessary

to place the POWER ON/OFF Switch (20, Figure 2-1) in ON position

to apply operating power. While the distribution panel is in

continuous service, additional batteries may be connected to or

disconnected from the distribution panel with the POWER ON/OFF

Switch in ON position.

f. Set CONTROLLED CHARGING STATION SELECTOR Switch (21, Figure 2-1) to STA 1 or STA 4

position, according to which controlled 12 VOLTS station is selected (paragraph 2-8.a.).

NEVER connect or disconnect the battery charging cable connector

while a circuit breaker switch is in the ON position.

g. Press through plastic cover and set circuit breaker switch for the selected 12 VOLTS station to ON

position. If circuit breaker stitch trips to OFF position, disconnect battery charging cable and battery

connections. The distribution panel cannot be used to charge the battery because of dead or shorted cells.

h. When circuit breaker switch is set and remains in the ON position (paragraph 2-8g above), the battery is

taking a normal charge. Proceed as follows.

i. Record the time, then check the battery again in one or two minutes to make sure there is no hard boiling of

electrolyte.

NOTE

Hard boiling is indicated by big bubbles rapidly rising to the surface

of the electrolyte, causing violent agitation of the liquid.

j. If the circuit breaker is still holding, turn the current control (2 or 7, Figure 2-1) clockwise until the

ammeter (5) indicates approximately 7.5 amperes. Record the time.

k. When soft boiling is noted in the battery (2 to 4 minutes), turn the current control counterclockwise for a

current indication of approximately 5 amperes, and again record the time.

1. When soft boiling is again observed (usually 5 to 10 minutes), turn the current control counterclockwise for a

current indication of approximately 2.5 amperes, and again record the time.

m. Continue to charge the battery on the chosen 12-volt controlled station for the time period previously

determined in accordance with the instructions set forth in paragraph 2-4a.
