I have the same problem with a 392
I have a taser also , what versions were you guys running?

I've had no battery issues since updating the Taser firmware but it's only been four weeks. The known problematic firmware was 11.3.7. The current firmware (12/22) is five versions newer.

It was so my fuck up. I apparently hadn't tightened the battery connections sufficiently.

I've had zero issues since updating the firmware on my tazer.

Hello everyone,

I am going crazy. I charge my battery almost every 3-5 days and it keeps discharging by itself.

I changed my main battery for a new one, same problem it discharges.

I went to the garage (not at Jeep no trust since I had problems with my dealer), they put TWO different "computers" to see the error messages and if there were any problems, but nothing conclusive.
Moreover I still have the battery (the new one) that discharges even though I made the modification "N1 bridged with N2 + 40A fuse + disconnect the positive cable of the AUX battery", so in this case the AUX battery is not connected anymore (as I understand) and I still disconnect (with the Tazer) the "Start & Stop"

At the moment (December 23, 2022) I am having removed my Tazer (+ unmary), recharging my battery (the new one, it is a week old) and then see if I still have my battery that drains WITHOUT the Tazer in my Jeep.

The version of my Tazer is 11.4.2 (so the last one at the end of this year 2022), I specify that I did a "reboot" + "two cycles".

The ONLY thing I didn't do was to "unmary" the Tazer to update the firmware (and this for several updates). I had read that it was possible to update the firmware and reconnect the Tazer without going through the "unmary" step and then "mary".

I am listening to your advice. Thank you for your help. For now I don't blame the Tazer, I'm just seeing if my battery still discharges as fast without it in my Jeep.

Did you unmarry, disconnect razed, and still have a drained new battery . Or you are trying that for the first time today ?

Disconnect the Aux battery negative and reconnect the positive, you don't want a loose positive cable laying around. The jumper reconnected the positive anyway and the jumper is not needed, just remove fuse 42 to prevent the PCR from seperating the batteries.

I did that on my 2021 JLURD and it still shows “start stop not available. Battery charging “.

I have done these tests now with the Tazer removed for the first time:

1. Unmary Tazer
2. My (new) battery has been charging for the moment for about 20 hours

I'll put my results here in a little while, the next step will be:

2. remove the external charger from my battery
3. leave my Jeep in the same situation, so at rest, as for the other times and see if it still drains.

I'll be back as soon as possible

Here is the state of my "optima Yellow" battery (new) and recharged.

My tests are starting without Tazer ... I'll be back in two or three days

Did you do 2 sleep cycles after unmarry?

 

[SwissSteph]

No, it should also be done ????

 

[SwissSteph]

in doubt I just did it

 

[Ratbert]

Did you do 2 sleep cycles after unmarry?

I've never heard of that requirement. Does that make sense?

 

[Rhinebeck01]

No, it should also be done ????
