check the front battery, you might want to unhook it and let it sit for a couple days to see if its shot also where r your grounds, and whats ur charged voltage and where does it drop to and how fast? with that much charging equipment and that size amp you should have that problem.

Normally I think, and anyone can correct me but Idle or will stay good charge at 13.4+ volts battery, and not running is around 12.4+ to 13 volts. All I remember is someone said that buying a battery that is on shelf for 6 months that you buy might not be fully charged, and if it is lower than 12.4 it might need to be charged before use or that the alternator is not charging. If your driving it will go back up to 14.4, but when thumping it bounces up and down between 13.4 to 14.4.
