Agree with you panos. Normally I steer by hand when it is tough. It is only when the wind is very light I have ever used the autopilot for a long time. Then the 1.4 ampere for the clutch is quite a lot. This pilot then uses four times as much power as my old simple wheel-pilot. If it is tough and the autopilot draw over 10 ampere, you cannot use the autopilot for a long time without the motor. I happen to be that sailor that hates to run for shore power all the time. |

Thanks for all the replies. All very helpful. I have a firm removing the DD1 and sending it to Jefa. They quote €200-500 for an overhaul and replacement parts. A fraction of a new model. Sadly I had only recently done an auto tuning reset on the Simrad Computer and the Auto was going like a dream even in choppy seas and cross swell. The only problem is if the boat is over canvassed and would be rounding up with or without the Auto engaged.
Jefa do seem to be nice to deal with , it just remains to be seen what their 'turn-around' time is at the factory. Still its fun to hand steer. Just done 300 nM from Hamble to The Scillies and now to The Channel Isles. Who needs an auto!!

Follow up on the DD1 drive. The unit has come back from Jefa, cost was 658 Euros incl return carriage and they fitted a new motor. Still cheaper than a new one.

Fitted the DD1 today. Not difficult and I see Jefa advise and supply a 10 A protective fuse. Something Hanse/Jefa should have supplied originally I reckon.

Glad you are pleased with Jeffa service. Everyone seems to say the same. Where is the 10amp fuse located?

Yes the 10A fuse was supplied by Jefa and the unit has long enough wires to allow it to be placed outside the sub floor cavity behind the wheel binnacle. Through the waterproof gland.

Upgrading to a hydraulic ram would save you allot of headaches and save power.

My autopilot stopped working last weekend. No errors. No movement. It moved the wheel a couple of times when I tried again. I removed the Jefa DD1 drive and it would not rotate when I connected it to 12V. Opened it from bottom side, took out the motor (carefull with the wires to the clutch) and opened this too. There I found that one motor brush was stuck. The spring had started to rust. Tried to clean everything, sprayed with WD40 and assembled all again. This will probably last for some time. But I should get a new motor. There was no water or anything. Probably the rust was just the humidity from the air inside. The motor was "made in china".
Anyone know where to get brushes and springs? |
