Aux Switches not Available

[Lionel Hutz]

I had a message on the instrument cluster this morning that said, “Aux switches not available while battery is charging.” Within 30 seconds they were available.

The first time I saw the message was a few weeks ago and I haven’t seen it since. Voltage gauge looked good so looking for ideas on why this would appear at start up.

Got an aux battery? Might be dying. If not, could be Star rail behind glove box corrosion as well.

Mine did it when battery needed charging.

Did you notice any hesitation when starting? If it were not for the message on the dash I wouldn’t have noticed any difference.

Nothing else besides my Tazer was acting weird. Charged overnight and has be normal since then.

If you are running on original/OEM batteries on a 2019 vehicle, you are long overdue for replacements. Dying, bad batteries are known to cause all types of weird electrical issues in the JL Wrangler. Depending on your engine, you may have a main and and aux battery. They both need to be replaced at the same time if you do not bypass the aux battery.

If you have an aux battery, seriously consider just replacing the main with a quality H7 battery and bypassing the aux. You will be much better off long term. I have done so and haven't looked back, as have many, many others on these forums.
