...If I remember the switch has one wire to it and the circuit is grounded through the body of the switch. If that's the case then you'd test by touching the wire contact and the switch body for continuity as you press the plunger.


I developed an error condition when switching to 4HLc & 4LLc (4WD works great) so I took advantage of some rare good weather and crawled under to meter my switches. I'm guessing an internal short in some of the switches since I get an open circuit when there should be continuity but note at the same time that there's continuity between the wire and the body of the t-case (i.e., ground). It's damned confusing...every one of the continuity checks had errors (either cont when there shouldn't be or vice versa).

I'm going to have to see a circuit diagram showing the various operation modes to interpret these results. Otherwise, it's just going to be a matter of biting the $$ bullet and replacing all of them.

I could tell you more, but suddenly I am run over by a truck.
