I have a 1990 chev 4x4 the actuator wire was unplugged, the guy I bought the truck from said it was broken... .I plugged it back in to try it but the
4wd does not seem to be engaging.. The light in the shifter to say if it is in 4wd is not coming on either. I would like to test the actuator manually, is there any way to force 12volt to it and get ti to engage while unthreaded from the front diff ?- posted
