Frequently Asked Questions
What is the primary function of a marine solenoid?
A marine solenoid acts as a heavy-duty switch, controlled by a lower-current signal from the ignition switch, to connect the battery to the starter motor for engine cranking.
What does the '3 terminal' configuration mean?
The three terminals typically include a battery terminal, a starter motor terminal, and a trigger terminal for the ignition switch or start button.
Why are sealed contacts important in a marine solenoid?
Sealed contacts prevent the ingress of water, salt, and debris, which can cause corrosion and intermittent failures in open-contact solenoids, ensuring longevity and reliability.
Can this solenoid be used for applications other than engine starting?
While primarily designed for starter motors, its robust switching capability and sealed design could make it suitable for other high-current DC switching applications on a vessel, provided the voltage and amperage ratings are met.
What is the voltage rating of the ARCO Marine MSW975 solenoid?
The ARCO Marine MSW975 solenoid operates on a 12V DC electrical system.
