Wind here in Wiltshire seems worse tonight than when Eunice tip-toed past on Friday. Perhaps it's from a different direction. Boat is rocking like, well, a rocking boat.

The M5 has overtopped the banks? Now that really IS bad news!

When I came onto the canals after a life on the Thames, I was rather taken aback at the prissiness of canal boaters whining at me to 'slow down' when I thought I was already going as slow as possible. They should try mooring on the Thames and having those 40ft gin palaces hacking past with their 18" wash, never mind proper waves in the sea!

As I understand it there are LOADS of different types of L-ion battery chemistries, of which LFP is just one. Some of them have much higher energy densities per unit of weight, hence the attraction of using them in EVs.

Thanks. Is that with the engine running? If so, the rev counter is not working which also points towards a dead alternator. (The alternator provides the speed signal which the rev counter uses to work out the engine speed.) Possibly something as simple as a broken vee belt. Can we see a photo of your new alternator please? Especially the back where the wires connect.

Start your engine, increase the revs and post a photo of the lights by the start key. And also a photo of that voltmeter please.

Yes she did. Greenford.

I often think this about canals. Can you imagine the reaction if someone designed a lock for the first time now, and submitted it for safety assessment?

I'm always suspicious to read things like this. As a repair technician myself I often encounter parts replaced by others who just guessed at the cause of a fault, then ran away or got sacked when their replacement part(s) made no difference. I would not be the slightest surprised if this is an old fault and someone replaced the alternator and never tested to check the fault itself was fixed.

Sounds HORRID!!

Ooh is there an engine available? I like engines. What is it?

You may not need to wait for and pay an electrician if you read my post from 55 minutes ago.

I reckon after 48hrs they'll be back on the mooring ns sucking on that bollard...

May I prevail upon you to refresh my memory? What is this "Dr Bob theory" of which you write, exactly? I wonder if Dr Bob knows anything about it....

I think it's unlikely. I've revived many a battery from beyond the grave just by charging them. My own boat here being a case in point. I've not been down for about eight weeks and when I got here the other day the Smartgauge said the domestic bank 1% SoC. Yes 1%, and probably for about a month. Bank voltage was coincidentally 10.1 too and after a recharge, they are back to performing the same as ever.

Bear in mind mrsmelly is 176 years old and thinks anything to do with electricity is 'newfangled'.

I think we can surmise "yes" to both these questions, because Bia had the boat three days before running the batteries flat. If either the fuse was blown or the main switch OFF, none of the electrics would have worked. SO given ten hours of engine running I think we can surmise the domestic alternator is goosed. Task now is to find out why. Oh, a thought. Starting the engine and just running it at tickover might well have not energised the alternator. Revving it up to get it charging is usually necessary. If this was not done, the ten hours of running yesterday could have been pointless as the alternator might not have been charging. So, back to Jen's question about what Bia is looking at to know that 10.1 figure....

From the OP's previous thread, probably west London.

Yes. But high cell voltage is not what happens if a cell goes faulty. A cell voltage like 4.00 will only originate from a charging source. Bear in mind I no nuffern about any of this...

A better illustration of the southern-centric nature of the mainstream news providers would be hard to find.

It is not possible for one of the four cells connected in parallel to go over 4.00V. They are all held at the same voltage because they are in parallel. So your BMS will see that voltage and disconnect at 3.65V, unless you have been fiddling with the settings. Welcome back by the way!

This is certainly the way I do it. I see a boat, it makes me buy it, then I fix anything crucial wrong with it. It's always been this way....

Bad news I'm afraid. The crisp packet teamed up with an empty milk carton, a coal bag and quite a few other random bits of rubbish and formed a ball of rubbish skidding/rolling up the high street and past the Cross Keys never to be seen again, at about 11am on Friday. I'll keep you informed if it turns up again.

Matty, Although I sometimes poke fun at the weather reports you relay to the board, I do appreciate them so thank you. Just thought I'd say.

Photos if you have any would be far more illuminating than words on a page. Thing is, steel goes rusty and surveyors point it out. These are two facts of life. Your steel boat was probably built with a design life of 30 years, so if it needs some welding to extend this maybe you are onto a winner! On the other hand the corrosion might take another 20 years to go right through the steel. Surveyor reports do tend to alarm people as they often don't point out the (usually) long timescales involved.
