Trying to fault find the rear factory locker in the 2013 GU.
At the diff end, with engine running and locker ON - No vacuum on the top hose
At the diff end, with engine running and locker OFF - There is vacuum on the lower hose
Tested vacuum at the solenoid.
With the locker ON, I have vacuum on the top outlet of the solenoid.
With the locker OFF, I have no vacuum on the lower outlet.
I measured the voltage going into the solenoid, there's a pink and a blue wire.
With diff ON - Pink = 0v
With diff off - Pink = 13.xV
With diff ON, Blue = 13.xV
With diff OFF, Blue = 5.6V
Most times the locker doesn't engage, but after all this checking I took it out and it did engage, not immediately, I had to drive for 10 metres or so before the locker engaged.
That 5.6V reading doesn't look right to me and knowing these things always die, I'm thinking I should just replace it & be done with it.
What do others think?
Thanks for any help.
