Headlamp Switch In ON Position
CIRCUIT OPERATIONWhen the headlamp switch is in the ON position, the A3 circuit connects to circuit L2. Circuit L2 connects to the multi-function switch and feeds fuses 3 and 4 in the fuse block. Circuit A3 is protected by a fusible link located near the auxiliary jumper post on the left toe box.
Fuse 3, a 10 Amp, powers the right LOW beam headlamp on circuit L44. On vehicles built for sale in Canada, the L44 circuit is double crimped at the bulkhead connector and provides an input to the Daytime Running Lamp (DRL) module.
Fuse 4, a 10 Amp, powers the left LOW beam headlamp on circuit L43.
When the operator selects high beam operation, with the turn signal stalk of the multi-function switch, circuit L20 connects to the L3 circuit. Circuit L3 powers the high beam lamps.
Power for the L20 circuit is supplied by circuit A3.
