I have no issue with people fitting a VSR. It is entirely their decision. The point is I get sick and tired of people on this forum telling everybody that 1,2 both switches are wrong. Explaining the differences is fine. The VSR is wrong for me and lots of others on this forum who have been sailing for 30+ years using a 1,2 both switch quite happily. Use your VSR But dont tell us we are wrong to use an alternative manual system
Of course, if you have a large deep cycle bank that you charge at high voltages or regularly de-sulphate, it might be a different story. In either case, if you want to fit a system that doesn't automatically charge the engine battery, that's your choice. Doesn't mean it was essential though.
The main criticism, at least on this forum, see post #44, is that a catastrophic failure of one battery during alternator charging might bring all the batteries down to a SOC where engine starting is not possible. Paul Rainbow thinks that this could easily happen, my view is that the risk is low.
I'll reply to you, but this equally applies to the other ranters in the latter part of this thread.
Firstly, you need to read what you are replying to, your post above is in reply to my comment "Leaving the switch on both is using it incorrectly. The reason so many of us don't like 1-2-B switches is because people like you don't understand how they should be used and what can go wrong when they are misused. "
I stand by that comment, using it on "Both" is incorrect.
Try reading post #27, where i took the time to draw up a quick schematic for the OP (which he has decided to go with), i also posted a schematic for separate switches. You see me telling him his switch has to go ?
How about post #24 ?
At no point have i said the switch is "wrong", even though some here clearly don't know how to use the ones they have fitted. I've certainly not said everyone must fit a VSR, i answered the OP, who specifically asked about the 1-2-B switch and his VSR, i answered his question. You came along, shouting about VSR and how they are not suitable for liveaboards. That's bollox. It certainly isn't suitable for all liveaboards, any more than any charging system is suitable for all of any type of boat or use. I fit various systems, suitable for the job in hand.
The reason a VSR is unlikely to be suitable for your particular setup is because you have deep cycle batteries charging at 14.8v, doesn't take a genious to work out that isn't going to do a FLA or SLA battery any favours. For those whos charging regime differs, VSRs work fine, even if they do liveaboard.

If i'm at all mistaken, you, or any one of the other ranters or people "liking" your reply to my post are welcome to point out where i have been "telling everybody that 1,2 both switches are wrong" or " tell us we are wrong to use an alternative manual system".
Nice that i'm allowed to "Explaining the differences is fine", once again i refer you to post #27. Differences clearly illustrated.

Using the switch in both is not wrong. Its only wrong in your head. For example, an overnight passage under engine. Engine has an electric fuel pump, fridge and electronics powered from the domestic battery. Join the batteries and run everything off the alternator. Why would this be wrong? Boat has ammeters on each battery bank and voltmeters. If one battery is taking an excessive charge you can see it on the meters you have the option to isolate the faulty battery. A perfectly acceptable instance where leaving batteries on both is fine and not wrong.
Boats have hugely differing wiring arrangement. Its not one size fits all

Suggest you read the posts, with best will in the world I can hardly say otherwise.Has anyone ever done that?
Is that an analogy of non VSR users against the enlightened elite who do and are positively sure they know best?It's a bit like driving an automatic car. Lots of people hate them (even though they haven't tried one) yet they are clearly more convenient.

The fact you needed to ask speaks volumes.
I do not give a rip for such criticisms, inaccurate assessments of use, or a looking down the nose, of how I, and seemingly many more, have conducted ourselves, with a little more than a modicum of success for quite a long time the methods employed which others find so annoying. As said before, do what suits you best and works, and leave us to do what suits us best and works...Simples.

NO it does not, otherwise why have a 'BOTH' position which charges all batteries in the domestic bank and the starter battery.Run your boat how you want, but leaving all batteries in parallel totally defeats the purpose of having separate batteries. If you want to charge all batteries and run all equipment from the alternator, a unidirectional VSR is a safer bet. Not that i expect to to agree.

Quite how that 'totally defeats the purpose' displays either a simple misunderstanding or an unenviable lack of understanding, particularly as the 1, 2, BOTH system is purposely designed to do just that? Repeat, 1, 2 or BOTH.
The system of course allows for separate employment and charging, as and when required, but certainly NOT exclusively as any long time user will willingly explain to any who will listen. I do hope your understanding will improve.
I'd agree with you, with the proviso that a low-loss splitter can be a better choice than a VSR, especially when more than 2 battery circuits require charging in isolation.

You are referring to very experienced skippers, who are fully aware of what they are doing, and have done so as I have said ad nauseum. We will not take any lectures from anyone displaying such arrogance.
The VSR fans seem to be mimicking the PC liberal left lobby
You are clearly so hung up on your misunderstanding of electrical systems that you are unwilling to listen to anything anyone else says. All that you need to know is contained in this thread, if you were not so stubborn to read some of it. The both setting should only be used for emergencies, whilst it is set to both you only have a single battery bank, can't you see that ?
[/QUOTE
Oh dear me, you are the one misunderstanding.
BOTH is only considered an 'emergency' position if for any reason the starter battery fails and the domestic bank can be paralleled to it to start the engine. There are others but that is the one I feel sure you refer to.
As previously explained, there is nothing to prevent the BOTH being used for charging purposes, or extra power at any time it is considered necessary. For me it is not common practice to use BOTH for normal domestic usage, having over 500ampH bank.
Keeping the engine battery separate is very good practice, but for you to be so dogmatic and deaf to the experiences of those who live with and by manual operation, and ignore the straightforward explanation of what BOTH is for surprises me somewhat. I am not putting a theory forward here, but the actual pratice of many years of trouble free usage.
I would be obliged if you keep such comments as to knowledge and understanding to yourself or for the sole use of your clients you charge for such pearls of such legitimate wisdoms.
I think Freedom35 needs to do some homework on PaulRainbow's background.
