A double tap on on/off button switches brightness to max.

Thanks.  Wish i'd known that before.  I'll try it when I am back on the boat next week.

Brilliant. I should of guessed as double tap was how dimmed old Raymarine. Thank you!

If you guys only knew how many times I played 19th century photographer in the morning after night passage, covering myself with the beach towel hovering over the chartplotter - before someone told me to use double-tap function!

The autopilot on my Hanse 385 has been causing big problems for nearly one year and I'm almost sorry for the technician. While cruising from the winter camp to the summer port in April 2019, the autopilot suddenly stopped (again and angain) with the error message "no rudder response".
Already two years ago I had similar problems with the autopilot, at that time my Hanse dealer instructed a company with the repair, which is an authorized dealer of B&G and a subsidiary of a large yachtyard in the Netherlands. At that time the cause was found to be a wrong mounted mechanism and it was fixed.
Because of the good experience with this company and because it also had the confidence of my Hanse dealer, I commissioned them to solve my problem. The technician made me hope that this repair would still be on guarantee or goodwill, since my boat was not yet 3 years old at this time.
Here is my anamnesis:
  • 1. on the first visit in early May, the settings on Zeuss3 were checked and the resistance of the cables was measured.
  • 2. The rudder angle transmitter was renewed on the second visit.
  • 3. on the 3rd visit, the cable from the rudder position sensor to the autopilot computer was replaced, this required two technicians and a 120mm hole had to be drilled in the back box.
  • 4. The log file from the plotter was read out and sent to B&G for assessment - no error was found
  • 5. The autopilot computer was removed and sent to B&G - no error was found
  • 6. the control panel has been replaced - without success
  • 7. on 16.10. In 2019, the engine was removed from the autopilot and sent to Jefa in Denmark.

Until today I got no message if there was a mistake found there.The technician was pretty sure that the Jefa engine was the cause of the malfunctions. I am very skeptical but also helpless and can only hope that he is right and that I can sail the next season with an autopilot that I can trust.

very sorry to hear about your problem.  It does sound like the technician is taking an analytical approach to solving the problem.
I believe that you will get to the solution.
Over 5 seasons and 10,000Nm my autopilot has been used extensively.  It has not been perfect and has dropped out on a few occasions, often when switching the VHF on after the other instruments.  But I sail.solo or with inexperienced crew and have confidence in it.
I hope that you get a successful outcome soon.

I had no end of problems with my Zeus2 during the first 12 months of use - frequently freezing or crashing the display - often when zoomed to navigate in very shallow or challenging situations.  B&G European support were very helpful, including lending me a replacement chartplotter, but were unable to resolve the root cause of the problem.   As a result of very frequently resets and wiping of the MFD memory I eventually stumbled upon the cause, which thankfully is now banished forever:

I use a passage planning programme which provides departure timing and passage length optimisation as well as route planning from the comfort of my home study or on board PC.  I find it very useful.  The programme allows uploading and downloading saved routes and way points in many different chart plotter formats.  Naturally as an all B&G vessel I chose to save in Navico's format .usr.  It transpired that saving in this format was creating a massive amount of hidden layer vectors which were slowing (at best) or sometimes crashing the Zeus2.

The simple solution was to exchange route and way point information in Raymarine format (.gpx) which the Zeus is very happy to receive or send.  The system has been very well behaved every since Thumbs Up.

Very interesting Paul, I remarked that my plotter (the original zeuss2 was changed due to lots of crashes without any reason in 2017 to a zeuss3) takes more and more time to start. I guess that it takes about 60 seconds until the warning screen is shown. I hope that I will find the time to visit my elisa on this weekend in Amsterdam so I can look what files are stored in its memory.

I´m curious to hear from any Hanse owner about the jefa drive as the source of error massage.

My Zeus 2 generally works well, so long as the tracking functions are disabled. 

Note that each plotter has its own track function.  You have to disable tracking individually, on both plotters. And when you update software, at least on my units, the default settings reappear and tracking returns in the background. Then things start to fail again. 

Both units are very buggy when tracking is on. System crashes. Screens freezing. Weird stuff with the AP. Once the tracks are deleted and the function disabled, everything works again as it should. 

I’ve had some low voltage alarms when running a winch. A jumper solved this issue. The masthead unit has been replaced once so far. 

I’d love to be able to integrate PredictWind grib files via my IridiumGo, but I haven’t been able to get this to work properly. Probably just as well - I suspect this would cause a system crash. 

With respect to the Jeffa DDI autopilot, I don’t trust it in any kind of challenging conditions, having experienced one absolutely terrifying failure. In settled weather, the only time I will use it, it works well. I added a Hydrovane as a back up and it is quite effective once things are balanced.

Hi Kipwrite

"I’ve had some low voltage alarms when running a winch. A jumper solved this issue."

I have the same problem. How/where was the jumper applied?

Many thanks


Richard
