Attached to the exterior of both battery compart-
ments is a danger plate. This plate stresses the need
to keep from making any sparks near the battery.
When another battery or 24VDC power source is
used for auxiliary power, all switches must be OFF
prior to making any connections. When connecting
auxiliary power cables, positively maintain correct
polarity. Connect the positive (+) posts together and
then connect the negative (-) lead of the auxiliary
power cable to a good frame ground. Do not con-
nect to the negative posts of the truck battery or
a ground near the battery box. This hookup com-
pletes the circuit but minimizes danger of sparks near
the batteries.
Sulfuric acid is corrosive and toxic. Use proper safety
gear, goggles, rubber gloves and rubber apron when
handling and servicing batteries. Get proper medical
help immediately, if required.
This plate is placed on both battery boxes and near
the battery disconnect switches to indicate that the
battery system (24VDC) is a negative (-) ground sys-
tem.
These decals are placed above the battery discon-
nect switches on the right side of the front bumper to
indicate OFF and ON positions of the switches.
