[CA] Ev300 and solenoid hookup
I have contacted the maker of the solenoid valves/hydraulic steering system. I am 100% sure that the the negatives and switching sides of the two (port & starb) solenoids are correctly hooked up. But, I am having issues with two alarms that are coming up repeatedly, rendering the pilot useless in the ocean. The two alarms are “DRIVE STOPPED” and “AUTO RELEASE”.

Is it possible that I need diodes?

(your manual incorrectly shows the grounds as + & - But obviously they are both - )

It seems like the P70r thinks there is rudder movement once Auto is selected. (kinda like it sees feedback from the installed rfu. But I do not believe there is any actual movement occurring)

Installing diodes certainly won’t hurt anything.

I have 1N4004’s, but thought 1amp rating could be too small.

thoughts?
