A correctly dimensioned electrical system contributes to comfortable and problem-free boat ownership. Therefore, batteries must be charged to the correct capacity, i.e. to supply the correct number of ampere hours (Ah). In turn, this requires an alternator that supplies a sufficient charge to the batteries. Insufficiently dimensioned, oxidized or badly connected cables, incorrect main switch, etc., lead to current leakage and insufficient charging. In other words, there is every reason to examine the electrical systems and, if necessary, improve it to attain the benefits of maximum battery capacity.
