i've recently been dealing with a dead battery because i didn't complete the reboot after flashing. the initial symptoms were the car was dinging and gauge cluster lights were flashing on and off and the start button was completely non-responsive to either turn the car on or off or even attempt to crank it.

i had to disconnect the battery in order to get all that to stop but even still, reconnecting it immediately resumed the craziness. the main battery was testing at about 6V and the ESS battery was testing about about 4.5V.

my question is.... is this how a JL responds to a dead battery outside of the ECU flashing complications i experienced. because if so, then how would anyone ever even be able to jump start their car if its just flipping out and flashing lights and non-responsive anytime the battery is too low to start. seems a little ridiculous for FCA to design it like that.
