My Beneteau Oceanis
31 has an engine
room blower that is engaged as soon as the engine
switch (Yanmar 3YM20) is turned on, and that runs until the engine switch is turned off (no thermostat).
Today, the blower quit. After some reading, digging and testing, I believe there is a fault somewhere between the engine switch and the relay (electromagnet side). I arrived at this conclusion after doing the following:
-- tested the relay separately from the circuit: electromagnet switch closes when 12V is supplied; and
-- reinstalled the relay on the blower circuit, manually closed the electromagnet side: the blower starts.
Am I on the right track? If yes, any tips on how to test the circuit from the engine switch to the relay? Any schematics for the Yanmar
panel switch? I am attaching a screenshot from the Yanmar
manual, showing the panel type.
Thank you in advance.
