ok hijack........
my 4x4 hasnt been working so just now I pull the therman acuator get some jumpers hook it to 12v and it extends just fine and i squez it and it pushes harder. ok that works. turn on the key(to run, glow plugs are cycling and everything) put it in 4h craul under and hook the dm to the plug and there is no voltage. the chiltons dosnt mention anyware in the thing about the 4x4 engagment system. is there a fuse someware im missing? im assuming there is a switch on the TC to tell the axel to lock? im at a loss here and would really like this to work so i can go hunting tomorrow.
