It was working it is only on rear wheels
U can see me my thread about Rear Diff Lock at PW & how I fixed it myself.
Also, I myself made the winch operative & designed a home made controller, I will show in picture also next time.
It saved the day for me.
The thing that screwed it was that I had the front left wheel axle replaced by mechanic, I stay & learn during the job, I was during dismantling but had to go during fitting.
He screwed the carbon bushes on the Hub Lock slip ring so the indication of Hub Lock & 4H lock which r automatic was there but in fact they were not locking the wheels.
On this saturday & sunday I removed this system & troubleshooted.
Found the culprit it was worn out slip ring & bent carbon bush on left side.
it was not giving juice to the motor to engage the Hubs.
Also tested a Jugaar how to bypass this auto thing if it fails in off roading.
Inshallah I shall write a detailed thread on Front Diff Locks soon for other members also.
