Hi guys, I hope here I find help, am really at a loss in the meantime. I bought a Fiesta Bj91 1 week ago. New system built in (nix dolles, 140W without amplifier etc), and since I drove for a longer time I simply always run out of engine, the battery is then completely empty. Now we have built in a new battery and alternator, after the installation the battery had turned on with all VUbrachers with running motor about 14V. That means the LiMa function Now the shit happened right on the first ride again, the new battery is completely empty again, we had to push the car. What can this be about? The system is definitely built in properly, the LiMa etc also I really don’t know what it can be anymore. A friend said the new battery (if we had to run another day with the broken LiMa) would be “deep discharge”, now I charge the new battery completely full, and hope it then, but I am Sceptical. Thank you very much!
