Here is the battery
And here is the voltmeter reading

Have you reset the battery sensor before now? If not, it's reset now with the battery removed. Make sure the battery is charged, put everything back together and see if it works now.

I thought it reset when I disconnected the battery to replace the aux battery.
And like I said earlier.. it worked on the way to work but coming home it was back at start stop not ready.. battery charging

What you really need to do is go through this post [https://www.jlwranglerforums.com/forum/threads/jumperless-aux-battery-bypass.95945/] and get that EES battery out of the mix completely.

If it wasn't removed from the main battery or had the connector unplugged, it wasn't reset. Just disconnecting the ground cables from the battery will not reset it.

Hummm..
So.it wasn't reset then..

 

[Joeshek]

Ok.. update
Had battery at garage.
Saying everything is just fine.
Load tested and whatever else they do.
Again saying it's fine.
So I guess when I get home I'm going to put it back in and see what happens..

Everything should have reset since it was out all night..

 

[Joeshek]

Now I'm second guessing the aux battery change.
What else can be causing this.

 

[elf883]

What’s the voltage at now ? I’m still gonna say it’s the battery , your not leaving anything plugged in or turned on I’m sure so hmmmm

 

[Mark Elliott]

Hummm..
Earlier today had same voltage and someone said it was fine.... I'm so friggin confused! Lol
My main is only 13 months old..
It shouldn't be going bad already.. or something else is wrong.. this shouldn't be eating batteries like this... do you think?

Actually had my main battery replaced under warranty right before it ran out, 13 months later I had to replace it, dead as a door knob. Was going to replace my aux battery but I don’t have one, found that out after I removed the fender and dropped the box. I guess I have the 48V battery next to the driveshaft since I have the 2.0L turbo.

Did you have to replace the 48V one?
