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 11-8, Page 11-12).
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.
LOCKOUT CAM CIRCUIT
The Pioneer 1200 is equipped with a lockout cam that allows the engine to be started only when the For-
ward/Reverse handle is in the NEUTRAL position. The lockout cam (yellow) is located on the back of the For-
ward/Reverse handle, inside the engine compartment.
NOTE: Be sure the cam is in the correct position. The cam should activate the limit switch only when the
Forward/Reverse handle is in the NEUTRAL position (Figure 11-9, Page 11-12).
The lockout cam circuit consists of the connecting wires, and a limit switch that is located on the Forward/
Reverse shifter assembly and is activated by the lockout cam (Figure 11-10, Page 11-13).
