2009 JCW In the process of gutting out my car for a full roll cage. Pulled the (new) battery out to access the firewall to patch it where the fresh air intake was. Put everything back together and - nothing. Dead - like the battery isn't even in the car. Ran a trickle charger overnight and it is still RED this morning. Tried "jumping it" off another car - nothing. Not even a click. 12V test light looks very weak between the terminals. ANY IDEA WHERE TO START on troubleshooting? Thanks Car is due to be loaded on the trailer on Sunday evening. Clock is ticking and I'm going crazy.
