Connect the jumper cables but do not crank the engine for two or three minutes or until the equalizer
indicator light has turned ON (which means the equalizer is ON). Both batteries must rise above 8 volts.
The Battery Disconnect switch can then be turned ON and the bus should have adequate 12 volt power
to start.
Equalizer Replacement
The equalizer is a sealed unit and is not field maintainable. Attempts by unauthorized personnel to repair
or undertake maintenance on the unit may result in voiding of the warranty, and may cause damage to
other electrical components in the coach.
If a unit fails and is within the warranty period, the Field Service Department of Gillig should be con -
tacted for further processing of the claim. If the unit is not within the warranty period, the Gillig Parts
Department should be contacted to obtain a replacement.
To replace the equalizer:
1. Turn the battery disconnect switches in the battery compartment to the OFF position.
Even with the battery disconnect switch OFF, all connections from the
battery to the equalizer remain live. To prevent personal injury, use
extreme caution when working on electrical systems.
When removing or installing equalizer cables, always use a wrench
to hold the inner nut (between the cable connector and the equalizer
body), so that it does not turn while you tighten or loosen the outer nut.
Failure to hold the inner nut in place can cause the connector stud to
turn inside the equalizer case, resulting in damage to the equalizer and
possible fire danger. Refer to Figure 9-7 for an illustration of the proper
cable installation / removal method. Never tighten the outer nut to more
than 120 in-lb.
2. Remove the cables or wires from the ground (GND), “+12, “ and “+24” terminals in that order.
Tape the ends of the cables to prevent short circuits and mark the cables so that they can be rein-
stalled on the correct terminals (12 volt lead should have a yellow band).
To avoid the risk of damage to the equalizer or another component
in the electrical system, always disconnect the “GND” cable first and
reconnect it last.
