If you know the engine the solenoid was designed for, then the main dealer would be able to tell you the part number of the mating part. BUT they may not sell loose connectors, and sell you only a complete harness. That would be eye wateringly expensive. I would save time and cut it off.

And also how close (or far) from the ideal wave form is the inverter output.

I would ask Butler Technik, they were very helpful when I was buying a Webasto system - though it was a few years ago.

If everything is perfect, probably not a corrosion problem, but in the real world with damp switches (from time to time) and poor wiring - for example another item sharing the bilge pump supply, then very small currents could flow more often than you would like or realise and corrosion would then be a real risk.

And don’t be tempted to use the hull as a negative return for anything (like cars do) it will work electrically, but it will also greatly increase hull corrosion.

Try walking around a couple of hundred meters to see if you can identify the source. Is it powered by you boat on by it’s own internal batteries? If powered by the boat see if running on it’s own battery helps. How long does the interference last for? If it’s exactly 13:28 everyday it must be something on a timer, do you have anything?

As an aside, I have found on old cars (pre lots of electronics), that when a number of lights etc start working strangely it’s a bad earth, possibly in the multiple connector. You could try running a temp wire from a good earth (such as the battery negative, or engine block, and then finding a negative wire on your control panel to see if that fixes it. If it does it will help to narrow the search for the dodgy connection, which may not be in the multi connector.

The reason they leave a layer of water behind is because they are cheap centrifugal pumps, but there are a couple of advantages, namely the pump doesn’t run dry and any oil or grease in the bilge will float on top of the remaining layer, and not be pumped into the canal.

BSS Requirements for Fire extinguishers, fire blanket and CO alarms etc are from page 46 in the BSS checklist that the examiner will use. They are also strict on petrol and generator storage etc, which is also in the checklist. It is not the easiest document to read, so if you get confused (I did the first time I read it), just ask on here and someone will answer. https://www.boatsafetyscheme.org/media/299273/bss-examination-checking-procedures-core-private-boat-public-interim-complete-compress.pdf The BSS is generally NOT negotiable, so as an example, even if you have brand new, very expensive fire extinguishers, if they don’t have the specified marking, they will fail.

I think it means that TV reception, wireless devices etc may be swamped by electrical noise, both sent back up the power supply cables (especially those on the same supply phase as you), and ‘transmitted’ through the air. You may not be popular with your neighbours every time you use it.

The River Seven has a few days every winter where the locks are shut because of too much water, and I am pretty sure there have been summer restrictions for not enough water, though I don’t remember exactly when.

If the crane operator has 3rd party cover, then your boat would not be covered, but the boat yours dropped onto would be, as that other boat would be a 3rd party.

I like spray foam as insulation, if you have a written agreement for min thickness AND you are there when it is applied you can ensure it meets the agreed thickness. Be upfront about this - it may cost a bit more as you are using more stuff and time. I also agreed to trim back the excess myself, as it is a crappy job and another incentive to spray a bit thin. Just buy a couple of bread knives and a big roll of bin bags.

Maybe obviously, but the log periodic aerial must point directly at the transmitter if in a poor signal area. If the cable needs waggling about, it sounds like either the connectors are dirty/corroded or the cable has an internal cracked core, in which case you need a new cable.

But none are allowed to be used in boats.

It’s a draft version containing the proposed changes which has been made available for interested parties to comment upon. They have also more clearly defined what constitutes an lpg leak that needs urgent fixing and the leak level that is considered as immediately dangerous, requiring system isolation. I shall have a read through and see what else is different in the next few weeks.

If it works fine, then a ‘better’ one won’t be better. That said I use a log periodic aerial on a pole, it works better in poor reception areas than an omni-directional antenna, but it must point directly at the transmitter or it will be worse than you have now.

I think they are sensitive to fuel gasses, and being typically mounted high up react to CO and Hydrogen, lpg being heavy tends to stay low down below the alarm and you smell it and fix the leak.

Or to say it’s perfect for continuous cruising what with it’s new gear box.

It may help to increase the ventilation to the housing as when the lights are on the temperature goes up the warm air will evaporate a lot of the moisture, if it is ventilated the warm wet air can be replaced by drier cold air taking the moisture away. Maybe need a breather pipe to outside the warm wet room.

Good point, if the EA gives permits to the water companies allowing sewage discharge directly into the river, why don’t they sell permits to boats as well???

Agree, ex 3 is the best method and the one I used. Plastic Barrier pipe was developed to minimise oxygen diffusion through the pipe walls and dissolving into the coolant as it will cause corrosion. So if you haven’t used barrier pipe I would replace it.

LPG may carry on, but the limiting factor for ‘mains gas’ boilers will be determined by the date they swap natural gas to hydrogen. However I would assume the industry to start selling hydrogen ready boilers that can be converted. But the demise of ‘mains’ natural gas is inevitable.

Whilst it is not yet law the “In the Heat and Buildings Strategy, published in October 2021, the government announced that they’re aiming to phase out gas boilers in UK homes from 2035.”

Natural gas as supplied to uk homes is Methane, and is anything but a green fuel, hence the government intention to ban the sale of natural gas boilers in the (relatively) near future.
