Trialmaster axle locker, how did they actually works=

[Myllis]

I wonder if anyone is familiar with the operation of the Grenadier axle locks. Ineos says the switch is electronic (i.e. the one's on the roof), but the lock itself is mechanical. Attached are two photo's, one with the lock open and the other one, the lock closed. The only difference is the 10% rotation change of the "front pressure plate ????", photos doesn't really tell you what actually locks the crown gears? Nor does it tell you how the information about pressing the button in the cabin comes to the locker?

Has anyone measured the diameter of the Grenadier Trialmaster shaftaxle and how many splines shaft has?

I understand the lockers in the Grenadier are Eaton E Lockers. Plenty of info and videos on line for these. I want to know can the activating power stay active when the vehicle is turned off. Should be a simple bypass to the relay.

Yep. I said the same in this post.
I have to think that IA didn't consider this scenario.

Plenty of folks have fitted e-lockers to vehicles equipped with ESC, ETC, ABS, etc. How do those vehicles react when the locker is on and automatic independent wheel braking is applied? If the axle is locked then independent braking will affect both wheels on that axle so the traction benefit of independent wheel braking is lost.
Arguably the locker is providing a superior benefit to ETC wheel braking (especially on the Grenadier) so is the issue more about axle and differential mechanical stresses? That said, is the resulting load of one wheel being grabbed by a brake under the control of ETC - while a locker is on - any different to the same wheel making and breaking traction on uneven or loose ground? That's often how IFS CVs get smashed.

If this is about battery drain when the vehicle is off that can be resolved in software by using a latching logic. If the locker was on when vehicle power was removed then put it back on when power is restored.

Probably not something to mess with during the warranty period.
