My Swan 441's autopilot system consists of a Simrad AP16 / AC40 head and computer controlling the 12VDC motor from the boats original NECO system using the computers solenoid outputs. This has worked well for years but on this trip the port direction drive started failing after several minutes of use then will not work again at all until is has had a few minutes to "cool off". After which it will only work for several seconds before failing again. The starboard drive is fine.
The problem appears to be the motor or very close to it. I pulled the cover to the motor electronics and the port drive relay contacts continue to operate after the failure happens, but the motor no longer responds. Any thoughts on what these symptoms point to?
Thank you,
GW
