I completely removed the auxiliary battery and wiring about 2 weeks ago due to a bad aux battery but learned something important if you do it this way. A 30 amp fuse is not enough to carry the max load of everything powered by the N1 terminal and when that fuse blows under those conditions it definitely lets you down and you don't have emergency flashers, windows won't roll up and down, etc. I did an amperage check and I was seeing 30.9 amps with heater blower at full blast and radio at about half volume, so I came off of N3 which originally fed the aux battery and is fused at 150A and ran a 6 gauge jumper to N1, I feel more comfortable doing it that way instead of a jumper from N2 to N1 which would have no fusing and could carry whatever current the main battery could provide.
N1 is connected directly to the aux battery and N2 is connected directly to the main battery, so the fused jumper directly connects the two batteries. Connecting to N3 to N1 puts the 150 amp High Capacity fuse in line between the batteries which will work unless that fuse is blown, which it does infrequently (and I suspect due to human error).Ok... I apologize, cause I'm not great with electrical systems.....Why was the preferred method before to go from N1 to N2 ?.....and now you are going N1 to N3 which allows the Aux Battery to be removed completely ? I have NO interest in ESS and will permanently disable mine when I get my JL....So this is interesting.....
There is - just unplug the PCR and disconnect the Aux negative. I've been running this way for 2-3 months with no issues. I think there might be a fuse you can pull in lieu of unplugging the PCR, I've been meaning to check when I have time because I want to do the same o my wife's pacifica and the PCR is much harder to reachYou guys have gone past confusing me....I wish there was a simple way to bypass the aux battery, my current way is to remove the negative ESS cable and then put a jumper on N1 to N2
My plan is to eventually re-purpose the aux battery as a backup/accessory battery, but haven't worked out the details yet. If you want two full size batteries the Genesis system is the only one I've seen. Some have reported charging issues with it, but I think they just need to move the battery sensor to the main battery.
No, the ESS system is still functioning as a single battery system like the new Cherokee has. And realize that the two battery ESS system is the upgrade to the single battery system.So, If the Aux Battery is completely removed, does this mean that the ESS system is permanently disabled and there are no issues or warning lights that are problematic ?
I do not advocate for removing the aux battery and when I rewire mine it will be to eliminate the issues related to the unmanaged interaction of the batteries by having some kind of manual management.I see. So the point of eliminating the AUX Battery is what then ?
Because it is harder to jump if it dies or cause it is acting parasitic on the MAIN Battery ?
