[CA] Ev300 and solenoid hookup

[Chuck - Raymarine - Moderator]

Oregoncme,

An intermittent drive stopped might mean there is a delay in the turning of the rudder. The solenoid may open quick enough but something is stopping the helm from moving quick enough. The Pilot needs to see Helm/Rudder Reference movement with 2 seconds of applying voltage to the ACU motor output. If it is over this, Drive Stopped or Auto Release could trigger.

It could be air in the hydraulics, a mechanical linkage problem or if it is controlling an electronic steering system it might be the propagation delay in that system. We have had similar problems with Hamilton Jet systems where the solenoids or relays are switching in quickly but the steering take up is slow. Some electronic steering systems design in a soft start that is not good for pilot control. - On that particular boat, Hamilton adjusted their software to react quicker.

Accordingly, you may be onto the correct path in solving the problem. Please see the diagnostic flow chart below:
