@lynn82, be sure to research and check for corrosion on your doors, hood, tailgate, windshield and hinges. You might still have time on the 5 year factory warranty to get it fixed.
Edit: Any Jeep dealer can do factory warranty work.
My 2020 with max tow came from the factory with the smaller battery, so that's not the problem. The dealer sold the vehicle with a bad or not fully charged main battery (and probably aux too) that is not covered under a lifetime warranty. The OP expected the batteries to be covered and is not...
Both my Wrangler and Gladiator have had the alternator voltage reach 15.1 volts due to infrequent driving not maintaining the battery charge and the system being designed to aggressively charge the batteries. 15.1 volts seems high, but it's because of the system design and not the size of the...
Wouldn't the dual batteries, the higher voltage of the AGM battery, the high compression of the 3.6 and a smaller starter all contribute to higher starting current?
If anyone is interested, this is the thread that lead to this setup that @Rhinebeck01 posted. It's a good read if you are bored. https://www.jlwranglerforums.com/forum/threads/ess-dual-battery-management.60034/post-1287541
Here is the new simplified version with one voltage gauge and one...
It was seeing the almost identical signals with an almost exact factor of 4 difference between the 2 that lead to my questioning what I was seeing.
Doesn't he 800A in the common ground wire that leads to both batteries include the 200A from the aux battery? That would mean 600A from the main...
Thanks for posting this. Are the current probes different which explains the difference in the scale between CH2 (50A) and CH3 (200A)? And for the main ground are you on the body ground wire?
Your symptoms seemed more like a blown N3 fuse than a bad battery, that's why I asked about the procedure. Let us know what you find out at the dealer.
Don't you miss Dan, the best service advisor ever? I'm pretty sure the reason he no longer works there is related his ratio of warranty repairs compared to straight billable hours. That's probably why no one wants to help, there's no billable hours involved.
I don't think this IBS SOC information is correct. This is from the IBS manufacturers website and describes how the IBS (called EBS by the manufacturer) uses the shunt connected to the battery to measure current, so it's calculations are based on the battery it's connected to. Can you explain...
I think that IBS information is specific to the battery it's connected to. Here's an image of other information available from jscan https://www.jlwranglerforums.com/forum/threads/new-twist-on-aux-unavailable.158752/post-3270587
