4.3.
Style A and B 4 x 12-Volt Precedent only:
With a multimeter set to 200 volts DC, measure the
voltage of the battery pack between the positive (+) post of battery no. 1 and the negative (–) post
of battery no. 4
(Figure 3-17, Page 3-20
or
Figure 3-18, Page 3-20)
.
4.4.
Style C 6 x 8-Volt Precedent only:
With a multimeter set to 200 volts DC, measure the voltage of
the battery pack between the positive (+) post of battery no. 1 and the negative (–) post of battery
no. 6
(Figure 3-19, Page 3-20)
.
5. Normal no-load voltage should be between 50 and 52 volts for fully charged batteries. The voltage of the
battery pack must be over 32 volts DC to allow the onboard computer to close the charger relay
.
If battery
pack voltage is too low to start charger, temporarily bypass the charger relay.
See Charging a Battery
Pack that has Low Voltage on page 3-37.
