High capacity alternators
I upgraded to a Balmar 115A alt. and external adjustable regulator./The whole deal cost me just under $500.00.
Later that season I also installed a wind turbine. Since then the Balmar just sits there looking pretty. The turbine does the whole thing, all seven batteries and it does it while I''m not there! As a result, most of the time my alternater is shut of leaving more power for the engine.
