brand new battery...but not getting power to the coach
used a volt tester the battery is brand new and fully charged, but for some reason, its not powering the rv, when i installed the new battery, went camping, turned on a few lights, instantly the lights shut off, when i had one on it was ok, put 2 on it would kill all the power, the weird thing is, when the lights came back on they were bright, not dull, also when i plug the rv into power or generator its fine. what could this be??
