CIRCUIT OPERATION
Circuit A3 from fuse 14 in the Power Distribution Center (PDC) supplies battery voltage to the headlamp switch. The headlamp switch has an
internal circuit breaker that connects circuit A3 to circuit L20. The switch connects circuit A3 to circuit L2 when the headlamps are ON.
The headlamp switch feeds circuit L20 which 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. The multi-function switch connects circuit L20 to circuit L3. Circuit
L3 feeds the high beam of the headlamps.
