While looking at the plotter earlier today, the instruments suddenly stopped working. No wind, depth, speed or GPS fix. Everything running on the Seatalk bus just stopped. Chart plotter still powers up ok. It shares the same fuse on the main power panel. Plotter is RL series and instruments are ST60's.

Any suggestions as to what may be wrong?
 
Autopilot head is in the cockpit on the wheel binnacle. It was under a cover and I wasn't touching it. Cant think its the reason......
 
Totally weird, because today after I had installed a new freshwater pump, suddenly our autopilot began playing up. No idea why...
 
Yes it does. It should take a feed through a 40amp breaker and have its own on board fuse. That then powers all instruments on the Seatalk network.
 
That was going to be my suggestion too. Obviously you need to know where your seatalk bus is powered from, which it sounds like you don't. Supplying power via the autopilot is quite common, and there is a small (2 amp, from memory) automotive blade fuse in there which protects the seatalk bus (obviously the main breaker is far too big for this as it has to supply the pilot drive unit). There should be a spare fuse in the autopilot cover, unless someone has already used it.

Should be a slight question mark over why the fuse blew, though, and definitely investigate properly if it happens again.

You are Gents! Replaced the fuse that had blown in the NMEA slot in the course comp - all now good. :D

As to why it blew in the fist place.......I will admit to fiddling when the power supply was on. :o

As it is, I now have two of Angus McDoon's YAPP 1 displays installed and working. One at the chart table ( which means I can get rid of all of the data boxes that have been cluttering up the screen of the chartplotter ) and a second on in the main cabin ( means I know what going on without even lifting my head off the pillow! ).

Thanks guys - very much appreciated.

You too prv. :cool:

Any piccies of YAPPs in action?
 
Not at the moment......but they are so good I will have a go at taking a couple of short movie clips of them in action.

I solved the "what do I use as a box?" issue as follows.

For the one in the cabin, I used the top of a plastic box that 50 business cards came in, cut out a hole the size of the display, sprayed the box black and sealed the YAPP in with some silicone. For the one at the chart table, I bought a small black project box from Maplin. Overall I am delighted! :D

The pump may have a magnet in it which, if close to the autopilot, could upset the compass??
