REVERSE BUZZER CIRCUIT
The reverse buzzer is a safety warning device that sounds when the Forward/Reverse handle is in
REVERSE. It functions to remind the operator not to leave the vehicle in reverse and to warn anyone in the
area that the vehicle is in reverse.
The reverse buzzer circuit consists of a reverse buzzer, reverse buzzer limit switch, fuse, fuse block, and con-
necting wires (Figure 11-7, Page 11-10).
The battery supplies power through the fuse block and is controlled by the reverse buzzer limit switch which is
activated by a cam located on the back of the Forward/Reverse shifter. When the Forward/Reverse handle is
placed in REVERSE, a cam depresses the reverse limit switch, closing the circuit. The reverse buzzer sounds.
