Bow Thruster only working to Port

[Grahambda]

Vetus bow thruster, was working fine during the sea trial (of course !) But now only port side working. Checked all the wiring seems ok, however clicking noise when pressing starboard switch, thinking solonoid , any other ideas before I drop the $$ on the spare part.

Note brand new battery installed close to the thruster and has a full charge.

Thanks

Sounds like a bad relay to me.

I would get with Vetus. Sidepower has a procedure that will allow you to diagnosis the complete system. Its easy.

Not sure of the difference but looked it up...
relay is in essence a switch with two positions, on and off. A solenoid, meanwhile, enables mechanical components to physically move and change position

Thanks plan to call them/local Tampa distributor ASAP.

Most bow thrusters have 2 or 3 relays that allow the DC power polarity to be reversed which reverses the rotation of the motor.

We had the same problem on our NP 39. It was a relay. Vetus thruster.

Side power has one relay. There are only a few #14 wire you can move around and find the problem in seconds. How clean is it down there. I have found a few times corroded wires from salt.

My Vetus thruster had the same issue recently. The cause was a bad connection in the control wires near the thruster unit.

Check the relays and connections for the control circuit. My guess is that the problem is there rather than in the thruster itself.
