 ELECTRICAL SYSTEM
SYSTEMS OPERATION
Water Temperature Contactor Switch
The contactor switch for water temperature is
installed in the regulator housing. No adjustment to the
temperature range of the contactor can be made. The
element feels the temperature of the coolant and then
operates the micro switch in the contactor when the
coolant temperature is too high. The element must be in
contact with the coolant to operate correctly. If the
reason for the engine being too hot is caused by low
coolant level or no coolant, the contactor switch will not
operate.
The contactor switch is normally connected to an
alarm system in the marine application. When the
temperature of the coolant lowers again to the operating
range, the contactor switch opens automatically.
