So I've got a coral 202 with three batteries and the huge International 3 bank charger and battery test system with meter. The 1st deep cycle on port side under the Guage is dead as hell. I can't get it out because the Guage tester thing is hitting, so I go to remove the battery beside, but it won't come out because the circuit breaker sticks out too far so to move to the right I'd have to remove the charger. What am I missing?
