[QUOTE="LsGuy, post: 8781153, member: 681035"] It's not normal, and usually indicates the aux battery failing (widely known issue on these jeeps). But, since your aux battery is fried, you already know what's causing it. The main battery is an agm from the factory, and I believe the aux is as well. Take it to the dealership, they usually replace the aux battery no questions. You have a 200-240 amp alternator (depending on options), a seperate motor generator, and 2 batteries. Unless you are running a super stout system, voltage drop won't be an issue, and big 3 probably isn't necessary. If you do decide to do big 3, research it since the wiring in these jeeps is more complex than standard battery alt setups. As a reference, I'm running 2k rms in my 21 jlu and the electrical system doesn't even notice it's there. Never any voltage drop at all. [/QUOTE]
