REVERSE BUZZER CIRCUIT

The reverse buzzer is a safety warning device that sounds when the Forward/Reverse handle is in REVERSE.
The reverse buzzer circuit consists of a reverse buzzer, reverse buzzer limit switch, fuse, fuse block, and con-
necting wires (Figure 11-8, 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 and activating the reverse
buzzer.

LOW OIL WARNING CIRCUIT

The low oil warning circuit consists of an oil level sensor in the engine, a dash-mounted low oil warning light,
key switch, and connecting wires (Figure 11-9, Page 11-11).
The light receives power through the key switch when the key switch is turned to the ON position. When the
oil level in the crankcase is low, the oil level sensor closes the circuit to ground and illuminates the low oil
warning light.
