[TG] Autopilot Voltage

RE: Autopilot Voltage
That depends on the circumstances. Assuming the pilot is driving symmetrically - and pilots are complex things and will vary their drive output from one moment to the next depending on a number of factors such as current drive position, the difference between heading and locked-heading, rate-of-turn, boatspeed, back-EMF from the motor and so on - and the load on the pump is symmetrical then yes, but there are a number of assumptions and caveats there.

The simplest explanation if you get a different sound when driving each way with a direct 12V supply is that there's different load on the pump in each direction, which sounds like a hydraulic issue. Who installed the pump? I'd get them to check the system.

Regards,
Tom
