Because of the increased demands a winch and other accessories place on the
DC power supply, many vehicles have multiple batteries-one to start the
engine and another to power accessories.
The WARN battery isolator prevents the problem of multi-battery drain. So
no matter how drained your accessory battery becomes, it will never drain
power from the battery you're depending on to start your engine.
