  • 1 Alternator, 2 Batteries, 120 Amp max
  • Includes Exciter Terminal
  • INBOARD AND OUTBOARD BATTERY ISOLATORS are solid-state devices which allow electrical current to flow in one direction ONLY, 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.
