Many people think that my book is comprised of my first-hand experiences. It is not. About 20% of the book consists of things that I have learned from others' experiences. In fact, when Thomas first solved this issue, a notation went into my Amel Book. When Doug submitted his bow thruster PDF, it had a perfect photo to go with Thomas's description of the wires. When you posted the photo of the burned contact point, it was added to the same page allowing Thomas's original description to come alive with 2 photos.
The result is here, which I will share with everyone:
The only credit due me is that I put all 3 things together, modifying that page 2 times as more information came to light.

Doug informed me that he remembered seeing a post from you in this regard and Bill managed to locate and forward it. Your write up was also helpful.
Bill is great at “soaking in” the knowledge from the group, organizing and accessing it when needed. A great resource for all Amel owners.

That issue happened to us 3 years ago and we reported on the solution here (06/06/18 #40108 ).
I would suggest carrying a spare relay as it happened to us again just recently. Note that we don’t use our thruster much, I don’t know if that helped delay the reoccurrence or instead accelerated it.
In our bow thruster, the oem relay is by Albright (sales@...) in the UK (they could only provide model SW202-317
equivalent to SW202-260 installed).
An equivalent relay is available at
evdrives.com in the USA.

I am glad it worked out and thanks for the photos. I was aware that this solution worked on at least two cases, but did not have the benefit of such exacting photos.
I am thinking that the life of this relay is probably about 10 - 12 years and if an owner has one in this age range disconnection from the motor, cleaning, and inspection is
probably in order.
How many hours did it take?

Our first solution of just cleaning the control box, turned out to be a coincidental repair. The Bow Thruster did work for a few days and then stopped working in one direction again. After some research and assistance from the group, especially
Doug Smith of Aventura and Bill Rouse, we narrowed down the issue to the main bowthruster relay. Yesterday we opened it up for inspection. The exterior of the relay was pristine, but found what is shown in the attached pictures. Some material has been physically
transferred, from a process similar to welding, from some of the contacts in the relay, to the opposing contact in the relay. After a thorough cleaning of the buildup on th econtacts and other surfaces using wire brushers and application of CorrosionX to the
springs, we have a fully operational Bowthruster. Now need to order a new one, as I don't believe we have as good a connection when the relay activates, due to the uneven surfaces of the contacts created by the arching that has been going on for a while. Thanks
for all the shared knowledge.
