Friend of mine finally replaced his 20+ yr old alpha
autopilot with a
Raymarine 6002 smart pilot. On their first trip with this new AP, crossing the
Sea of Cortez, every 7 min the AP would do a 25degree couse change to port. When they finally arrived off the coast of
Baja they re-initalized the AP and took the
boat out again and it did the same thing. They turned off their Adler Barbour 12 volt refer that uses 6 amps when running and this has cured the problem. There was no low voltage problems as they were motoring the whole time. The 2 systems are on different circuit breakers. Any suggestions as to how to have both systems running at the same time would be appreciated. Thanks
