trying to get E-drive working

[trw]

so Im not sure my E-drive is working at all on my CJ.

if I turn the dial in the glovebox, nothing happens it seems, the light doesnt even come on, the funny thing is, when I replaced the carburetor, after the install, the E-drive light was on and I tried working the engagement dial to get it off, but it stayed on for a few days, then it turned back off and hasn't been on since, I'm not even sure how the E-drive works as far as the method it uses to lock the Transfer Case into part time, so can anyone guide me as to where to start

The Quadra track uses vacuum to engage and disengage. If you some how got the vacuum lines mixed up then that most likely is your problem.

Here is a great photobucket page with everything you need to know about the quadra track -->> Quadr track pictures by fuzzgremlin - Photobucket

And - here is a vacuum diagram.

I had this same problem with my e-drive. It turned out to be 2 things wrong. The vacuum lines were old and in really bad shape and the PO ran the engine vacuum source to a ported source instead of a full manifold vacuum. It took me a while to figure out why e-drive wouldnt come on at idle.

Definately check your vacuum lines first and go from there.
