A friend of mine has a Raymarine
and it is having an issue.
About 30 seconds after going to auto it displays "Low Battery" (might be "Low Voltage"). During this time the drive unit does not try to steer. You can alter the required course but it does not actually try to steer.
I have check the voltage at the panel and the feed into the head
(both in standby and auto mode) and showed 13V nominal so it is getting the required power. When going to auto there is no voltage shown at the drive.
The unit feeds via the seatalk
cable power to the other displays downstream from it and I also showed 13V nominal on those.
I suspect this is an internal issue to the unit but if there is something anyone can think of that might help it would be appreciated.
