How to remove the service battery from a Jeep Wrangler JL

Model: Jeep Wrangler JL, MK 4 - Years 2018-2026
Part: Instrument cluster

In this video we can see how to remove the auxiliary battery of a Jeep Wrangler JL: the youtuber shows us how the ignition of a certain light on the dashboard alerted him that there was something wrong with the automatic start function. These vehicles have two batteries, and the auxiliary one manages the start & stop system, and if this is discharged, it is surely what the light on the dashboard signals. It is not easy to reach because it is under the fuse box, but it is still a possible job. We remove the main battery, then remove the cover of the fuse box, fixed in turn by 4 bolts and the six lateral ones, all numbered; we will have to remove the tabs and electrical connectors on the bottom of the box; we will have to remove other fixing bolts, and finally underneath we will find the battery, from which we will have to remove the sockets to reassemble them on the new one, which will be lacking. Put it back in place with its cover and redo all the connections of the fuse box, fixing it with its bolts. Put the starter battery back in place and the job is done.
