2.14 12 Volt Electrical System
Overview
The truck 12 volt electrical system provides elec-
trical power for the switches, solenoids and other
electrical components in the paint system. An
alternator recharges the batteries whenever the
truck engine is operating.
The electrical system is equipped with heavy duty
circuit breakers that protect the main electrical
circuits and can function as disconnect switches to
deactivate the respective circuit. A main battery
switch located near the breakers on some mod-
els activates or deactivates the truck and paint
deck electrical systems. All wires in the electrical
systems are color coded or numbered to make
identifying circuits easier.
Most paint system equipment is operated by
switches in control panels in the cab or rear control
station. Fuses in the cab and rear control station
panels protect individual circuits activated by the
switches in the panels.
A separate 12 volt DC electrical system and on-
board battery provides electrical power for starting
the auxiliary engine that powers the air compres-
sor and hydraulic pump. This system also powers
the compressed air heat exchanger cooling fan.
An alternator on the auxiliary engine recharges
the battery whenever it is operating. This electri-
cal system is totally isolated from the truck and
paint deck electrical systems.

Truck Main ON/OFF Switch
The main battery switch, located on the passenger
side chassis, just behind the cab, activates or
deactivates the entire truck and paint deck
electrical systems. The battery switch is a safety
feature that must be turned ON before operating
the truck and turned OFF when it is parked and
unattended. To avoid damaging the charging
system, make sure to wait a minimum of 30
seconds after the engine is shutdown before
turning the battery switch OFF.
The switch can be locked to secure the vehicle
or to meet tagout/lockout safety requirements.
Always make sure the main switch is turned OFF
whenever the truck is unattended.
