Transfer gear warning light flashing 2005 lr3

Im not sure about that Globetrotter. Being a solenoid it generally is in one position when energized, another position when not. The switch itself is simply computer driven. So the real question is what state should it be in by default, should it be energized when in high and not when in low, or the other way.

Does the actuator commands the solenoid to switch to high or low? According to the diagram those 2 circuit wires goes directly to the solenoid and the actuator itself has its own circuit wires unless the actuator is not working causing the tccm not to engage the low/ high range... Have you check your solenoid and see if your changes the voltage when hitting the switch? I'm very curious to know how your operate when selecting the high/low range.

So the solenoid does not control high or low itself, it controls high/low or clutch control. So I think by default its energized because you are in high or low, then during a gear change its de-engergized to pull the clutch to allow the gear change itself to take place. One the gear change is complete, its energized again.
Annoyingly I have yet to find the actual tech article on the box, but its made by Magna so there should be a very detailed article somewhere. Just not in RAVE (or so I have found yet).
I have attached several things that may be useful from the training manual. Also not the clutch position sensor, possible issue on yours? Make sure all these items are unplugged and plugged in again, as that is often the "fix" for some issues like this.

Actually found some tech info form LR. So again default is constant 12 v when in clutch position. When in gear change, it energizes. Really what is happening is the t-case electric motor is doing all the work, this solenoid is a helper to facilitate which action the motor is doing. The motor can vary the clutches, just like how the rear diff works (contrary to what people think, it does not simple lock or unlock, it's variable). Or the motor can be used to make the change from hight to low or low to high. The solenoid simply changes how the motor works with the transfer box. Make sense?
