I have a 1985 H34. I need to gain access to my batteries in order to complete my installation of a new Pro Mariner Pro Sport 12. charger, specifically I have to connect the positive and negative connections to each battery that run from the charging unit. My problem is the location of the batteries under the starboard side of the cockpit. The opening is way to small to fit thru and my arms aren't long enough fully reach the battery boxes. Has anyone experienced this and if so how did you finally get close enough to the batteries themselves in order to work on them?
