Inboard Battery Isolators (No. BI-0702 - BI-1602)

INBOARD/OUTBOARD BATTERY ISOLATORS
Battery isolators cannot be used on 12 volt charging systems with 24 volt trolling motors
or newer outboard engines with rectifier-regulator charging systems.

Battery isolators are solid-state devices which allow electrical current to flow in one direction only, thus permitting the alternator
to be connected directly to two batteries without fear of one higher charged battery discharging into the lower charged battery.
Both batteries are always being charged automatically, in proportion, to their needs, whenever the engine is running. When battery
isolators are used in conjunction with selector switches, it is not necessary to change the switch position to provide for charging
of both batteries. Isolators provide proportioning of the output or charging current on the alternator to the batteries as required,
regardless of switch position. Rated for use with 10 to 350 amp alternators on 12, 24, or 32 volt negative ground systems.
