Re: 4WD part-time light question
 

I once did a poll here in this newsgroup. 62% of the readers who responded had
a 4X4 light on their Jeep that malfunctions somehow.

There's a vacuum switch on the xfer case with several hoses coming out of
it. They branch off to the vacuum motor on the axle, and a vaccum signal
coming from the intake manifol to a harness sorta deal mounted on the
firewall by the battery. There's an electrical switch on the axle vacuum
motor with one wire on it that goes through to the dash light: I.E., the
light comes on once the collar on the axle engages and trips the switch,
which grounds the light.

Ther's been several variations on this system over the years (before Jeep
finally just dumped it) but they all work essentially the same way.
