I have a 78 Sovereign
. When I hook one battery up ( the one on the right facing from the outside ). The electrical system works, I can push test on the solid state panel etc. When I hook the other battery up, nothing, no juice.
Do both batteries need to be hooked up at once fo it to work? ( like a primary and secondary battery )
Are these connected in parallel by default ?
I hooked up a solar charger to battery 1 under the assumption that the batteries are connected in parallel and therefor it would charge both batteries, but now I'm not sure if that is correct.
