Relay Box
The relay box is located in the cab of the vehicle (see Figure 3-14). The box interior consists of a
series of relays, fuses, and connectors that supply the electrical systems for the Alley-Gator Right-
Hand
TM
.
Relays: A relay is a series of switches influenced by a common coil but controlled from a remote
location, such as a limit switch or proximity switch. Although there are 2 different types of relays they
perform the same function. Each relay is labelled in accordance with the operation it controls.
Fuses: There are six fuses installed in the relay box; only three are resetable. All fuses are located at the
center of the relay box. The three resetable fuses protect all lights circuits. All fuses are labelled as to
the circuit they protect.

Eight standard proximity/limit switches are located on the arm and body of the ASL (9 if a ladder or a
crusher panel is installed, 10 if a top door is installed). They provide safety lockouts as well as
controlling the operational cycle of the pendulum and arm. See
