Charging System
When the engine is running, the ammeter needle (refer
to Figure 7.5) should be to the right of “0.” Left of the
“0” is discharging.
Electrical System
Electrical power is supplied from two, 550 CCA, 2 volt
batteries (refer to figure 7.6). These batteries supply 12
volt DC electrical power to operate the aerial platform
electrical and electrohydraulic components.
A Warning
Batteries give off hydrogen and oxygen that can
combine explosively. Death or serious injury can
result from a chemical explosion. Do not smoke or
permit open flames or sparks when checking the
batteries.
A Caution
Even with low voltage electrical systems, severe
arcing can occur. Electrical shock or component
damage can result from contact with energized
conductors. Use caution when working with any
electrical device.
The batteries are behind the door on the left side of the
turntable.
Emergency Power Battery
The emergency power battery (refer to Figure 7.6) is
behind the door on the right side of the chassis. The
battery is automatically charged when the engine is
running.
