Selector Switch for dual battery systems

Anyone that has multiple batteries and charging systems should own one of these.It only took me one time to have an auxillary battery go dead on me on the water from an unseen short that slowly drained a battery to fix this issue. Used one of these for years and never regretted it! When storing for a prolonged period of time this will also save your battery from unforseen drains that could cost you hundreds of dollars in battery replacement. Save your batteries! Very simple install! Buy it!
