Wiring on an Aerostar E-4WD transfer case.

Hello

I was woundering if anyone has the wiring diagram for my AWD tranfer case?

I don't know anything about an Aerostar, but an AWD TC should mean that there is no wiring. AWD is achieved with a viscous coupling , not with a shift motor or electric internal clutch.

The Explorers and other SUV's have optional switched TC's, with A4WD. Good luck,

What year is your Aerostar? My manual says that the E-4WD transfer case (model TC-28) has an electronic module which controls the internal electromagnetic clutch, and the self diagnostic indicator system.

What do you want to test? The electromagnetic clutch is pretty simple to test.

Hello

What I want to do is test all the plugs that goto the tc. The 4wd is always engaged and its a pig on gas.

Ok how do I test it. Please point me in the right direction to test it.

It should not always be engaged unless there is a short. Unplug the electromagnetic clutch, and see if there is power at the connector. It shouldn't have power unless the module gets a signal from external sensors to apply the clutch.
