My car is bricked. Despite leaving it on a battery tender which says the battery is at 100%, nothing works. Door locks, headlights flicker, the push won’t even flash red or green (it’s just dark). I thought leaving on a tender would avoid this. I left the battery disconnected for 2 hours to reset everything. Nothing. Any tips how to get it awake again? Thanks!

Someone posted this : ignition on/engine off pull high beam lever 5 times and press brake 3 times within a 6-10 second time and battery light will pulse a few times indicating its been reset, "

Test your battery with a multimeter to make sure it really does make good voltage.

This car does some real weird crap when the battery is below 10 volts.
