Headlamp Switch In OFF or PARKING Lamp Position

CIRCUIT OPERATION
Circuit A3 originates in the Power Distribution Center (PDC) and supplies battery voltage for the headlamp switch. A 40 Amp fuse protects the A3 circuit. The headlamp switch has an internal 24 Amp circuit breaker that connects circuit A3 to either the L2 or L20 circuits, depending on switch position.

In the OFF and PARK positions the headlamp switch feeds the L20 circuit that connects to the multi-function switch. Circuit L20 powers the high beam circuit when the operator flashes the headlamps with the turn signal stalk of the multi-function switch. When the operator flashes the headlamps with the stalk, the multi-function switch connects the L20 circuit to the L3 circuit. The L3 circuit feeds the high beam of the headlamps.
