Anyone have Pics of the N1 to N3 Jumper when deleting th Aux battery?

[Gregors]

Very soon after I purchased my Gladiator, I pulled one of the hood plungers out of the harness and layed it down to disable the ESS. I won't ever use it again so I would like to just get rid of the aux battery all together. No sense in waiting for it to go bad or take out the main battery, or carry the extra weight. Gladiator is a 2022 Overland with the tow package. I can pull the aux battery easy enough, but I'm still in the dark on what exactly I need to do with the fuse jumper. Thank you, Greg

You do not need a fused jumper, that is redundant as the fuse array it attaches to is fused.

I ordered a 8", 6 gauge cable with 5/16 (M8) eyelet ends from Battery Cable USA. when received, I just chucked the eyelet ends in a vise and gently pinged over the ends to a 90 degree and installed.

Just pull fuse f42 and remove the negative cable from the aux battery to the main batter. Doe the same thing and cost you $1 in electrical tape with plenty left over.

Hey. I’m new and learning; why would someone want to do this? If I don’t have the aux switches, is this something I need to look into?

The Aux Battery is there to keep the computers stable during ESS events. If you disconnect it, everything runs off the Main Battery. If you always turn ESS off, you can get by without the Aux Battery.

I am not sure what the jumper does? I simply removed the aux batt and ran the positive aux terminal to the positive cable of the main. It just fits (long enuf) to do that. My ESS is disabled. Never had any problems requiring jumpers-is that because my Gladiator is a simple Sport S?

Thank you. Exactly what I was looking for!! Greg

Picture worth a thousand words. Can you give me a few words here so I can tie this into the rest of the thread? I am slow. Thanks, Wrench Safe!!

The aux. battery powers electronics when the Electronic Stop/Start system is active. I disconnected my ESS as it was very annoying. It is my understanding that In order for the systems that are powered by the aux. battery to keep being powered by the main battery after the Aux is removed, you need a jumper wire on the fuse block so that the terminal that "was" powered by the aux. battery will now be powered by the main battery.

bypassing the aux battery is easy. just pull N42 fuse and disconnect aux neg battery cable and tape it off. Why do this? To remove aux battery and not get other computer warnings.... there is a thread on this. Easiier than using a physical jumper bypass. For those who do not wish to use ESS. Of course one could simply use the dash button to not use ESS. The bypass means you simply monitor your main battery and have disabled the aux bsttery

I have often wondered the same. I did the bypass, but left the AUX battery in place until my bumper to bumper coverage ends. I know that people were doing a couple of different jumpers before someone discovered that you can simply remove the F42 fuse and disconnect the AUX ground (bypass).

Sorry I missed this and was caught up in a few things over the weekend. The jumper is not entirely necessary - as others have said. But if you want to fully remove the aux battery wiring entirely, then it is. There is also some differences in the wire harness between vehicle years. Somewhere around 2021/2022 they made a wire harness change - so be aware of that. Theres quite a few threads here that discuss it.

For me I wanted to remove the aux wires from connecting to the PDC just to free up space. But I did not remove the wires from the truck entirely because I didn't want to unwrap the wire harness. However, I also did not want to just keep them connected. If I kept the factory harness connected at the N1 and N2 terminals then I would have to do a REALLY good job wrapping up the aux + wire under the PDC so it did not touch and short out with the aux - wire. Because naturally if those factory wires were connected, they have powerI fully removed the battery - because if it is disconnected why even have it there? That is my thought anyway. I also already discarded the battery and I'm not gonna buy one just to have it sit there.

Post 192 has more photos. Feel free to browse the whole build as I have more info in there about my particular reasoning and methods of removing the aux battery.

One caveat though is there is some concern among the knowledgeables that the fluctuation of voltages during an ESS event with it running on the main battery could cause some electrical issues or codes. However, I dont think anybody has experienced any actual problems yet and several have done this method for a few years now.
