Hi newbie here
just bought a '89 fourtrack with no 4wd working

I have checked the vac pipe to the box,i can hear the solinoid clicking when i press the 4wd high button but no 4wd.

Could anybody tell me which on is the 4wd solinoid i should check for current as i can see two solinoid type things on the box.

Is it the one right at the back of the box or the one halfway down on the n/s ???

Many thanks from an ingnorant newbie
