Headlamp Switch In ON Position
CIRCUIT OPERATIONWhen the headlamp switch is in the ON position, it connects the A3 circuit from the PDC to circuit L2. Circuit L2 connects to the multi-function switch and feeds the L4 circuit (for low beam operation). The L4 circuit connects to a bus bar in the fuse block. Circuits L43 and L44 connect to the bus bar in fuse block and power the low beam headlamps. Circuit L43 supplies voltage to the left headlamp. Circuit L44 supplies voltage to the right headlamp. Both the L43 and L44 circuits have separate 10 Amp fuses located in fuse block. Fuse 17 protects circuit L43, and fuse 18 protects circuit L44.
When the operator selects high beam operation with the turn signal stalk of the multi-function switch, circuit L2 connects to the L3 circuit, Circuit L3 powers high beam operation.
