4KQ diff question

[quattro2@ix.netcom.com]

The indicator light for the center diff lock on my 87 4KQ does not go out. I have confirmed that 
the diff is unlocked by putting the car up on 4 jack stands and "driving it" Center diff does 
unlock. I have checked the switch on the tranny with a multi meter, and it seems fine, as is the 
wiring... Moving the diff lock linkage by hand also has no effect.

Is there any adjustment that can be made to the diff lock on this car?? I see that the Book of 
Bentley says adjustments can be made to the "early version" cars. Any ideas??


Thanks


Bill
