79 Series dash light

Have you tested the Globe? start with the simple stuff of globes and fuses. 4wd is in the transfer case and the diff lock is in the diff, so I would say they are independent. good luck, Ray

When you first turn to key to the On position, usually all of the globe indicators light up until you move to Start. If the green 4WD one comes on, it's not the globe.

I have fixed the problem . Switch into gearbox cleaned { loose or bad connection }Diff locks must operate through this switch ,as they will engage now .

I don't have any trouble with my 4WD light coming on, but occasionally it doesn't want to switch off, but just needs the lever pushed completely forward.

While on the Canning recently, the rear diff lock wouldn't engage after a minute or two, and a bit of gentle forward & reverse, so I switched it off and didn't use it. Have just gone down and checked both diff locks, the rear one just flashed & wouldn't engage at all, while the front one engaged immediately with a distinct sound. I wouldn't use them at all, unless both front & rear lights had stopped flashing, the potential for horrific, and expensive, damage is too great.

The rear diff lock set up is a bit of a dog's breakfast! Wires partially exposed, and a stone/rock guard that is barely strong enough for light gravel. When my ute was only a couple of months old, I travelled up the Strzelecki and hit a large rock mixed in with some Road base they were spreading on one section. Didn't notice anything until later in the year, when we were travelling on a wet gravel road. A number of lights were flashing, including the 2 diff lock lights. Dealer suggested a cost of $1200plus for repairs, but they managed to keep cost under a grand, no warranty either.
