BATTERY ISOLATOR SWITCH
The battery isolator switch is designed to isolate the battery from the boat’s electrical circuit.
It is used when the boat is in long-term storage to prevent the battery becoming drained, during
maintenance (this should be done by qualified electrical technician. See also “ELECTRICAL
SYSTEMS” in the section “SAFETY”) and in emergency cases.
