I have no green 4h light on my dash. I want to have a good rummage around the switches and solenoids situated on top and at the sides of the gearbox/transfer box.

Access appears to be very difficult indeed.

Am I missing something?

Any tips on gaining better access - can anything be gained from getting into the top of the area via the gear/transfer levers in the cab?

Or maybe disconnect the prop shaft or remove the supporting chassis member under the gearbox?

Any other tips?

Cheers, Terry
