Lewmar Thruster controller failing?

Hi all;

I have a 2008 Nordic Tug 32 with a Lewmar bow thruster - it works and has never actually failed to work ... but.... there is an interesting problem I'd like your help with.

When I push the Power button to activate the thruster controller, I hear a relay or solenoid "click" sound from up near the thruster itself in the bow; and the joystick controller lights come on. But frequently the lights immediately go out and I have to push the Power button a second time - again hearing the same "click" sound up front and then they will stay on. Occasionally it takes 3 tries before it will stay on. Anyone else have this experience. Could the solenoid or relay up front be starting to fail?

Thanks - any inputs are very welcome!
Don

It sounds to me as if the remote switch is sending power to the relay, but the relay is not actuation fully. The first place I would lock for a problem is the ground connection going to the relay and the ground connection to the windlass motor. Be interesting to follow this thread.

Sorry for the typos. I should have known it was not a wise idea to attempt to type this post on my phone's small keyboard.

I recall another thread recently regarding a Lewmar thruster. For that one, I think the problem was deterioration of the thruster controller itself. I think it was on the flybridge and had weather/corrosion issues.

I will be interested to see how this pans out. I also have a Lewmar. My flybridge controller sometimes needs to be pushed twice. I am too far away from the solenoid to hear anything. But I may be heading down the same path as it path. I'll try and fnd the old thread....

Ok, this was the thread.

Haunted Lewmar 185 thruster

Different problem, but I'm still suspicious of water damage to controller. To the OP, does your problem controller get wet at all?

I had the boat with the bad Lewmar remote and related TF post.. If I recall correctly the remote switch assemble has three wires feeding into it; a power input feed and two return legs, one each to trigger the relay into port or the starboard thrust mode.

To test the system simple jump these wires from the power feed to each separate leg going back to the relay. If the thruster works in both directions, with no clicking or issues, the problem has to be a bad switch. While testing allow the thruster a moment to come to a complete stop prior to shifting into the opposite direction of power.

When my remote switch failed it would not function at all going to port, but it worked find in moving the boat the other direction.

Looking forward to hearing other suggestions.....

Often a cleanup of the wires and contacts at the switch with a spray like Corrosion Block can work wonders. Especially on fly bridge connections.

Brian, with your upper helm controller sporadic, did the lower helm controller work OK?

Mine has done the same thing (minus the clicking noise...I don't hear any) since I bought the boat 5 years ago. Sometimes it'll take a couple attempts for the thruster to turn on. Since it's always worked on the second or third try, I've never investigated further. I'll be curious if someone here finds out if/what the problem is.

FYI...my only control is in the pilothouse where it stays nice and dry. This thruster and control were installed in about 2008.

Yes, at least I think so. I can't recall having to try more than once on the pilothouse switch.

Follow up Lewmar controller

Just to finalize this thread, after talking with Lewmar it turns out that the controller itself was faulty - I bought a new one on ebay for $150 and everything works fine. The controller has some internal electronics that start to fail; apparently not an uncommon problem.
