Overloads
Avoid prolonged cranking or the addition of extra electric
devices which will drain the battery and may cause
excessive heat.
Multiple Battery System
The crane’s 24V system is powered by two 12V batteries
connected in series (Figure 7-1
).
Always refer to wiring diagram for correct connections. Be
careful not to reverse the battery connections. Installing
batteries with reversed electrical connections will not only
damage batteries but also the crane’s electrical system,
voltage regulator, and/or alternator.
Maintenance
Checking Battery State-of-Charge
Special equipment is required to properly determine the
condition of a battery that has been in service. However, a
voltmeter can be used to determine a battery’s state-of-
charge by checking the voltage between the battery
terminals (Figure 7-2
) (Table 7-2).
This open-circuit test is the simplest test but not as accurate
in determining a battery’s condition as a hydrometer test.
The advantage is that the cell covers do not need to be
opened, eliminating the possibility of cell contamination and
electrolyte spill.
NOTE Do not use this test method if the battery has been
recently charged by a charger or alternator. Recent
charging places a high surface charge voltage
which is not a true indication of actual battery
voltage.
Table 7-2. Open Circuit Voltage
Consult the manual provided with the test meter for detailed
test information.
