Interface boards and water filters

Tim is in the UK at the London Boat Show today, so no sailing. No doubt there will be loads to report from that show. I remember about 3 years ago going to the Southampton Boat Show and having a whole day wandering round looking at boats and different parts. The only thing is that Boat Shows are better enjoyed in the company of someone else. So you can discuss the different boats and gadgets and whatever.

We are trying to get an onboard computer system working for monitoring the new electric drive and doing various other things like converting SeaTalk to NMEA, chain counter, Navtex, backup navigation computer etc. And of course being a computer for blogging and the like. The 12 volt LCD screen has what looks like a normal connector, but the size is just slightly different to those available here. There are two standards, both have 5.5 mm outside diameter, but one has 2.1 mm inside diameter and the other 2.5 mm inside diameter. Those available on the island have 2.1 mm, which means they don't fit. I was looking for some other wire to connect up the interface box and I came across a number of 5.5 mm power connectors. Sadly they were all 2.1 mm inside diameter too!

One of the problems we have been having is the fresh water pump continuing for quote a few seconds after we turn off the tap. We have traced everything and cannot find a leak anywhere. We thought last time that maybe there was an air lock somewhere so we flushed it and it did seem to work slightly better. Today I fitted a new water filter and found there was an air lock. I tried flushing it, but cannot seem to get rid of it, in fact the air lock seems to re-fill up after I have flushed it. This is strange, I would have thought if air is getting in, then water is getting out, but we cannot see a leak anywhere. We'll just have to investigate further.
