If the control system is acting like the thruster is already down, I'd suspect whatever sensor determines it is in the down position, not the controls/relays.  You already said your up-sensor was not working right, so why not the down-sensor too?  Did you repair the up-sensor already so that you won't burn up the new motor?

Hi All,

I have been stricken with the dreaded bow thruster burn up! This has happened to a few of you so I am reaching out because we are stuck for a fix. The usual story - Hole in BT is sitting slightly higher than the pin-lock. The up-sensor was a bit erratic and probably allowed the BT to go up to high and jamming the up-down rod. My model does not have a fuse and sure enough we burnt up the motor. I now have a shiny new fabriqué en France motor and it is installed. When commanding the motor to go up from the helm it goes up. When commanding to go down it buzzes like it is already down. Rod does not move down. We are thinking it is one of the orange relays on the circuit board. We changed the diodes out to be sure it was not them. Does that sound right? Any ideas would be appreciated. We are trying to leave and this is keeping us dockside. Thanks in advance.
