Outer Limits 4x4 Board

G'Day,
I have bought a 97 80 series cruiser (full time 4wd) and I am having a drama with centre diff lock engagement. It is an ABS model, so it has the viscous centre with the centre lock only activating in low range. From what I can gather when L4 is selected the ABS light will come on and the 4wd indicator also (that's what the manual says) however this does not happen in mine. I also cannot hear any sort of engagement going on when I select L4 so I am assuming that it is not activating. It does go into low range though, just not locking the diff. I have checked the fuse and it looks fine (but will replace just to be sure).

Does anyone know the following:

a) How the centre diff lock is activated e.g. servo or similar
b) Are there any relays I should be checking and where are they located
c) Any basics or obvious things I could check first.

I intend to get a dashboard switch as per the non ABS models and do the manual activation mod that I have seen elsewhere but want to get it working properly first.

Cheers for any help,

Dave

hey when my centre diff lock stopped working there is a small electric motor that activates it and the motor just stopped working and i replaced it now its all good. Someone correct me if im wrong about the motor activating it.

ive got an 80 with pushbutton activation, but im guessing theyd be near on the same, and i had the same issue as abauer01 i just replaced the electric motor and shes all sweet again

Thanks for the info guys, I will check this. Is the motor accessible or will I need to drop the g/box?
