Lewmar says they could not find anything wrong with the system when I sent it back to them, but I was trying to use it with my
Maxwell solenoid
control box, which may be the problem. I give up. Now I see in the West
Marine catalog that they have a different looking model, but the specs are the same. Also, they have a
remote antenna kit, which opens up another question.
My
advice to you is to use it only with a Lewmar solenoid
control box.
Good luck.
