I'm now about a month into running without the AUX ... everything works fine and my ESS works normally. As mentioned it will throw an ESS error after six cycles, but I really could care less as it resets with a start up and with my commuting a rarely see six ESS events. I have noticed that prior to when the system was stuck on "charging" the voltage reading was stuck on 14.0-14.1 ... immediately after removing the AUX it jumped to 14.3-14.6, now it seems to have settled between 12.9-13.2.Here's my ESS journey ... System worked without issue for the first 18 months before the "Battery Charging" message appeared. I removed both batteries and found that the AUX was bad. I replaced the AUX and at the same time upgraded to an Odyssey 48-720. 4 months passed and the "Battery Charging" message reappeared. I removed both batteries once again assuming it was the AUX, but actually discovered the problem this time was with the Odyssey. (Props to Odyssey on warranting the bad battery in a expedient manner) I suppose I could have or should have tested the Odyssey first, but in my defense the AUX still needed to be tested and we all have to love how Jeep buried this damn thing in the bowels of the engine compartment.
Now with almost 4 yrs of ESS disdain in both the JL and JT forums I question the need of the AUX for MY use and have concluded that for me it is more of a liability. I have recently chosen to delete the AUX battery completely and rewired based on how the Genesis system is wired by disconnecting the ground and running the AUX positive to the primary battery. This accomplished the same as the N1 to N2 jumper, but I wanted the AUX gone. The vehicle and systems have been working just fine ever since. The ESS system does have a 6 cycle limit and then the ESS light will activate, but it resets at vehicle restart. I might still purchase an ESS eliminator plug. (I don't need a Tazer) I am now more confident that I will be able to jump start using a jump pack that is always in the vehicle. Yes, a problem could still exist deeper in the system, but I feel this removes the possibility of the AUX itself making the system inoperable, not to again mention the issue of access.
If I find down the road that I need more amp/hr capacity I will look at installing a Genesis dual battery system.
