Underhood Lamp: Description and Operation
CIRCUIT OPERATION
Circuit M1 from the Ignition Off Draw (IOD) fuse in cavity 2 in the Power Distribution Center supplies battery voltage for the underhood lamp. A
mercury switch, in series after the lamp, connects the lamp to ground on circuit Z1. When the hood is raised, mercury inside the switch moves to a
position where it connects circuit M1 to ground circuit Z1, illuminating the lamp.
The underhood lamp is wired in parallel with other components on circuit M1.
