RAM 2500 Van V6-239 3.9L Magnum (1995)
Underhood Lamp: Description and Operation
Circuit M1 from the fuse 2 in the fuse block 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. Circuit Z1 terminates at the right side of the cowl panel.
