Help! I don't know if I'm posting in the right place. I'm new to this so please correct me if I'm screwing up. I thought I'd take the Crossfire out for a ride because it was a nice day to put the top down. First of all, I couldn't unlock the car with the fob. Everything was dead. Opened the door with the key and no power anywhere. Thought my new battery was acting up. Couldn't get a reading on the voltmeter so I got my jumper pack hooked up and the alarm started going off and scared the crap out of me. Disconnected it and alarm silenced. put a charger on and it would not work until I disconnected the ground. Battery is fully charged, but still is not allowing any power to the car. I'm totally lost and would appreciate any help and or advice that anyone can provide. Thanks, Rich
