Not really. It is an internationally recognised standard and there isn't an equivalent over here. The relevant bit is about tolerance of a live short to earth resulting in a very high current through the diodes. If they blow open circuit, you no longer have an earthed hull. The ABYC spec aims to make sure this doesn't happen.

Haven't you worked it out yet? The butler is an automaton!

You get very little charge out of solar in the depths of winter, not enough to run any significant form of heating. If there was enough oomph in the sun, you wouldn't need heating anyway!

Anyway, it is topics like this that remind me how glad I am I insisted on our Empirbus system for Telemachus. Makes this sort of thing a doddle to implement!

Ok so the issue is only with the TP. There were various iterations of the TP box, I see you have a "black box" one whereas I have a "silver box" one. The bottom of mine looks quite different from yours. Sorry for being confusing! Do you know if the brushes in the alternator were checked/replaced? I say that because badly worn brushes can cause the TP to become intermittent, and I believe it can also damage the box. when DMR comes back he may have some better ideas.

Ok thanks for the extra info. Before we go onto the Travelpower I'm a bit puzzled by your original point about no ring main. Normally I would expect the Victron to power the ring main from the batteries, in the absence of shore power/generator, or the Travelpower. Can you clarify if the Victron is indeed still powering the mains sockets from the batteries when the engine and generator are off? I think you probably have an older version of the Travelpower than me, so take the following with that note of caution. And in fact DMR I think has the same version as you so believe him over me! Firstly, and I know this is probably a silly point, you do know that there is an on/off rocker switch on the bottom of the Travelpower box? It is on, isn't it! my Travelpower requires 12v power from the engine ignition switch to get going. So I would have thought that regardless of the alternator, when you turn on the ignition and the TP, there should be some sign of life from the TP box. If not, I would suspect the loss of the 12v supply from the ignition switch to the box. If the box seems dead despite getting 12v from the engine supply, I would suspect the box rather than the alternator. Finally, although I'm generally a DIY sort of chap, I did have some problem with our TP alternator recently that I couldn't fix. I used the services of Ed Shiers of Four Counties Marine and would heartily recommend him. Last resort, obviously, if we can't sort it out!

Hi there. I think we will need a bit more detail and / or photos. Remember, you know what you are talking about and can see the items, we can't! so you talk about a victron. That is a make. But what model are we talking about? I'm guessing it's a Combi but guessing leads to confusions! you mention a secondary alternator but so you mean the domestic 12v alternator, or the Travelpower high voltage alternator (with braided cable connecting it to the Travelpower box)? either way, I wouldn't expect any sort of direct connection between an alternator and the Victron so until we know more detail, I'm loath to suggest anything. what should happen is that the Victron (assuming it's a Combi) acts as an inverter taking battery power and converting it into mains, or takes the Travelpower's mains and passes it through. So if there is no mains at all, it means something up with the Victron. But, as I said, more detail please before we get too carried away!

Yes I think this could be a sensible approach but it depends on exactly what the OP wants it to do. If he only wants to be able to turn the light on and off using the remote, whilst it is off at the wall switch, then putting the relay in parallel with the switch will do that. But if he wants to be able to put the light on with the switch, then off with the keyfob, he needs 3 way switching.

I meant use the existing light but have no switches (that you use, anyway) and control the light with one of those relay units and two keyfobs, one in your pocket and one stuck on the wall near where the switch is now. It talks about 140mA with "all relays operating" and the data sheet is for models with up 3 relays. So I think we could say around 50 mA for one relay, which I suppose isn't a lot. Yes, good idea but the ordinary light switch would have to be replaced with a push button or other momentary-action switch.

This would do it - caveat about relay being permanently on applies though. https://www.maplin.co.uk/p/quasar-single-channel-wireless-remote-control-kit-l26bk

You need one with a double throw relay, ie both NO and NC contacts. I'll have a look... Oh but also, the relay will stay energised in one of the states, so if say you turn it on with the relay then off with the switch, the relay remains powered indefinitely. Perhaps it would be easier to get another couple of keyfobs and stick them on the wall next to the switches?

Our Mastervolt Combi has an adjustable charge voltage up to 16v. I think 16v is the absolute max so if you set 15.5v you get 16v with cold batteries. If you set 16v you still only get 16v with cold batteries. But that is plenty. And Mastervolt chargers and combis are fairly common. worth bearing in mind that when you set eg 15.5v, it doesn't increase the voltage for the high current part of the charge much. It is only when the current tails right off that it gets up to the set voltage. Which makes it pretty much replicate Trojan's (and other manufacturers of that sort of battery) recommended charge profile. i find the Trojans quite happy with the Iskra alterntor's 14.5v or so during summer. I equalise them using the Combi powered either from the mains or from the Travelpower, a couple of times over the winter 6 months. I recently checked the sgs, they were all around the nominal 1.270. After 4 years.

As far as I'm concerned having a historic boat doesn't make you a snob. Or cliquey, or one of the self-perceived "elite". Those attributes derive from the person, not the boat. Unfortunately there are some who are like that. But one thing is certain, it is not all or probably even most. I don't know you but I've no reason to think you are a snob/cliquey/elite. If I did have such reason, it would be because I'd perceived it from your behaviour, not from your boat.

Nothing much on this forum is important! Anyway, I appreciate that bickering is a pita to watch. However, I suggest that if it were you who had someone making up lies about something you didn't say, then using those lies as a stick to beat you with in public, whilst being backed up by a pack of baying bloodhounds, you might, as I do, find it difficult to ignore. I'll try it on you sometime when you've forgotten, and see how you react. It is a comment based on your apparent inability to comprehend plain English.

Of course. But I didn't use the term "anyone". Why do you keep making up stuff that I didn't say? Perhaps the clue is in your earlier comment "Of course you always select your words very carefully" - you are desperate to make out I said something I didn't, but because I chose words that don't support your accusations, you are sulking. I did say "any late 70s person may..." . That means any late 70s person may. It doesn't mean "All late 70s people do...". Perhaps you don't have English as your first language?

As far as I know the only "claim" Steve made was that it was a "Josher-style bow". I'm not even sure what that means, but it certainly doesn't mean it is pretending to be a replica of a FMC "Josher" historic boat. If it was such a replica I wouldn't have bought it. Who wants a leisure boat with a tiny back cabin and an enormous open hold? Maybe "Josher-style" should be taken in a similar vein to "Gangnam-style"? Only those who are envious and therefore seeking a justification to dis the boats, make the claim that it's supposed to be a replica bow. Quite sad, really.

Post 44 - as is clear to anyone who can comprehend basic English, having said I didn't know Trevor, why or how could I possibly have an opinion about the state of his faculties? Any normal person could see that the idea is ridiculous. My point was a general one that people who were excellent boaters in their prime, may eventually fall foul of failing faculties. Almost certainly will, unless they take the sensible decision to quit. I was thinking of car driving where there comes a point that someone makes the decision for you. I didn't say Trevor was such a person, you are just making up a silly interpretation to support your faux outrage. post 50 - do you disagree that in general, when people get quite old their faculties are at risk of eventually fading? If so, can I have some of your elixir please. This was a general and IMO obviously correct statement. As per post 44 I have no idea of the state of Trevor's faculties and only a person lacking in any logic and comprehension would think so. Or with an agenda with a need to support a random rant of false outrage. post 56 ditto. You are quite irrational if you think such a statement is somehow a slight on Trevor. None of these posts imply that Trevor is suffering from some age-related impairments. It implies that he could be. Clearly for someone in their 80s this is a possibility But since I have never met him, how could I possibly know whether he does or not? i did not "challenge" whether Trevor had been a commercial operator, I asked the question. Repeatedly, but of course the cult followers consider such information sacred and it took a while to get a clear answer. Knowledge is power. Although whether he is still a commercial operator in the generally accepted sense remains unanswered. Now could you please identify the "uninformed observations" I made about Trevor, or retract your libellous accusations.

You make such a fuss about this, the only likely explanation is that in fact it is you who is envious!

I don't see anything here that makes any slight on Trevor or his personality. I've never met him but happy to take your word that he is a gentleman of the first order. But let's hope he doesn't take himself as seriously as you do! He might even have a sense of humour!

They are similar to Trojans, a little more expensive but possibly a little better. https://www.tayna.co.uk/US2200-Deep-Cycle-Monobloc-Battery-P4117.html There is a page 2 of the data sheet but when I post the link, it turns it into just the first page

I appreciate that to leading figures in the cult it will seem blasphemous, but to normal people it was a joke. Or are you saying the post is wrong and Trevor WOULD have a problem? Or is it just mentioning his name the offence (like in Judaism)?

What have vegetables got to do with it?

It's a bit confusing because you said "coming from the South" in your OP. Coming from the South means you are coming along the B&F. It is therefore very difficult to see how your bow fender could be anywhere near the glass. But if you meant coming from the East - from the Glascote direction on the Coventry - and turning left onto the B&F then it can be a bit squeaky. The bridge just before the junction is very narrow and thus not easy to start the turn until the stern is clear, by which time the bows are getting a bit close to the glass. I find that it makes a huge difference how you go through that bridge - if you can get the boat at a bit of an angle to the left as you go through, it makes the turn much easier. A lot of people don't notice the in-fill on the left at just above water level, and bounce their bow off it thus putting the boat at completely the wrong angle to make it round in one go.
