I had been trying to work out why my batteries weren't behaving as expected, considering they were new this year. I had blamed it on my old 12v fridge, which certainly was dying. Then I blamed it on my new 240v fridge which has to run in conjunction with an inverter and it is true that this was taking too much power to sustain it long term. But it was only when I talked to a knowledgable fellow moorer at Fradley that the light dawned.
There is no book to tell you how long to run your engine for in order to fully charge the batteries because it depends on so many variables from the size of your alternator, to how much power you actually use. So I had listened to various people telling me how long they run their engines for and then did similar. But what I hadn't asked was how much power they use or what size their alternators were or even whether they were usually attached to shore power or not. Chris, the knowledgable moorer, was the first to suggest that I just wasn't running my engine for long enough. I had thought that when my volt meter hit 12.8 that meant the batteries were fully charged, but no! When I started running the engine for an extra hour a day I immediately spotted that the volt meter started ticking down much slower, in other words, it would stay on 12.8 for much longer once the engine was off. I can now watch the tv for a couple of hours and only lose .2 of a volt However, Chris also pointed out that a volt meter only told part of the story; I also need an amp meter, but that costs well over £100 and will have to wait. - but all this is very exciting for me, but probably dreadfully boring to read about!!
Of course I'm running without a fridge at present, but tomorrow I am hopefully swapping my 240v fridge for an older 12v one. If this works out well, then my family have generously agreed to club together and buy me a new 12v fridge as a combined 50th birthday and Christmas present.
Meanwhile, for those who are not into the technical details of my life, last week I returned to the wigwams of Wolferow to meet up with some friends for a couple of days of meditation, discussion and whisky round the bonfire. I brought an extract of a poem to share with them which reflects where I feel I am spiritually at present, so I thought I'd reproduce it here. It is an extract from a poem by Walt Whitman called 'Song of the Open Road':
'Afoot and lighthearted, I take to the open road.
Healthy, free, the world before me,
the long brown path before me,
leading wherever I choose.
Henceforth I ask not good fortune,
I myself am good fortune.
Henceforth I whimper no more,
postpone no more, need nothing.
Strong and content I travel the open road...
From this hour, Freedom!
From this hour I ordain myself
loos'd of limits and imaginary lines.
Going where I list; my own master
total and absolute.
Listening to others and considering well what they say.
Pausing, searching, receiving, contemplating,
gently but with undeniable will.
Divesting myself of all the holds that hold me.
I inhale great draughts of space;
The east and the west are mine,
the north and the south are mine...
All seems beautiful to me.'
