  1. They have unloaded the stern to get access to the rudder by the looks of it
  2. The image in the article looks like a microchip with bling, that makes me a bit dubious as batteries tend to have fewer connections, or at least in series. May be parallel on a circuit board?
  3. IT is a specialist, try him
  4. Yes, the inevitable system replacement is on the cards. I like the pricing of the B&G these days and it seems that the quality and reliability has been retained with the budget range.
  5. I connected the unit up and used a fan to spin the impellor. Seemed to respond to speed and direction but unsure of the quality of the signal. Periodically there is a packet of pulses that come through, one is direction and the other speed. Still a bit of playing to be done.
  6. If the clunk occurred only in neutral then it could be engaging gear spasmodically due to incorrect adjustment of selector or similar, the heat present could induce the selection if it was slightly off. When it clunks can you move just the gear selector arm slightly one way or another to see if the clunk goes away? But if it makes the noise when drive is engaged makes this less viable!! Does it do it both in reverse or forward? Can you isolate the clunk to either the motor or saildrive? I have read about the oil type change for earlier saildrive models, has the oil been changed? Was it the
  7. Thanks Dave, it is probably a trip to nowhere trying to keep the system going as something else will fail! What was surprising was the coating of dust and dirt on the unit, a total black-out especially with it being at the top of the mast and inside a fairly sealed unit, it is a wired unit. Maybe there is some ionisation that attracts the dust?? It cleaned up well though.
  8. After some time I opened up the sensor to find it full of dirt and dust, covering the opto-sensors and partially covering the opto-ball?? What an amazing idea I reckon. I will try to test is with oscilloscope, the pulse frequency is the speed and the pulse length is the direction, all on 2 wires. Results to come!
  9. Here was some good info: nx2_service manual.pdf
  10. Hi KJ, I didn't ask them to repair it but that may have been a good option as the bearings were all OK. They didn't offer to repair it either but I will check it out when I get the old unit as I work with some electronic people and have access to some test gear. I hope the new unit will offer a few more years of service ahead.
  11. Over the weekend I removed the wind transducer from it's base and took it to the local Garmin agent who set up a bus network to check it with a new one. It produced a 0 knot signal when compared to a new unit. So I've ordered a new transducer as mentioned in previous posts. It wasn't straightforward testing of the output like a normal transducer but luckily had a test rig to try it out.
  12. I had some nice wet weather gear but the zips and appendages were metallic and corroded quite badly
  13. The unit is a wired unit straight into the bus. I would like to hear how Kiwijon gets on, weather not the best at present
  14. 180S, I haven't checked the server setting but as it was working recently I would hope it wouldn't have changed. I had trouble getting set up info and hopefully tomorrow I will be able to see the settings. Looking like a faulty wind transducer or connection issue. It would be good to have another good transducer to swap with.
  15. Hi Matt, it does come with a RS232 to USB cable, that may be useful. It outputs 0 knots rather than a dash or an error message which I thought may help diagnose the problem area. I have visually inspected the connection at the base of the mast and measured the voltage supply but I wasn't sure about what I would find that was correct. It may mean a trip up the mast but not in this weather, thanks for your input.
