[CA] [CA11] Autopilot upgrade

[Chuck - Raymarine - Moderator]

rfadler,

Q1. As this is a sail boat it's preferred to be operated under sail without the engines charging the batteries.
A1. This action was directed for troubleshooting purposes alone. As suggested, should the problem not manifest itself when operating under power, with the engine charging the electronics bank, then the fault would be determined to be insufficient power to the autopilot.

Q2. The house bank provides the power for the autopilot and while it's a new bank with substantial reserve it is very possible that other electronics could be pulling momentarily pulling the voltage down too low. What is the low voltage limit of the course computer?
A2. 10.8V. The drop need only be temporary (ex. surge demand) for the limit encountered.

Q3. Does the ACU-400 have a similar low voltage limit?
A3. Yes.
