We have started having a problem with the original Autohelm ST7000 autopilot fitted to our 1991 Santorin. When sailing along it will just stop working without any warning until such time as it veers sufficiently off course to trigger the OFF COURSE warning. Hitting Standby and turning the boat back onto the original course and then pressing Auto will restore it for a time before the problem returns an hour or so later. No other error messages come up on the display.

I know this is an old unit but we would like to keep it in good working order as a backup to our recently installed Raymarine X30 Smartpilot which incidently we are very pleased with.

Any ideas or suggestions welcome.
