We need to start by checking the voltage coming from the switch going to the GEM.
Then we need to check fuse 104 in the battery junction block. This is what feeds the relays for system.
Lastly, we need to find out if the GEM is grounding the relay. This is the orange and light blue wire that is highlighted below.
The way we do this is put your red meter on battery positive and then the other on this wire. Engage the 4x4 and see if the meter reads battery voltage. If it does, then the GEM is working.
However, I suspect the GEM is going to be the issue so let's run through this and let me know what questions you have.
