Headlamp Delay Module

CIRCUIT OPERATION
When the operator turns OFF the ignition switch and then turns OFF the headlamp switch, the headlamp delay module powers the headlamps for approx 45 Seconds.

When the ignition switch is in the START or RUN position, circuit A22 powers circuit F87 through fuse 9 in the junction block. Circuit F87 supplies the IGNITION ON/OFF signal to the headlamp delay module. Circuit Z1 provides ground for the module.

When the headlamp delay module activates, it connects circuit A3 from fuse 7 in the Power Distribution Center (PDC) to circuit L2. Circuit L2 powers the headlamps through the multifunction switch.
