Alternator Charging Question

Paul - stop reading what is not written..
WHERE did I say I always switch to both after starting ?

The bit you highlighted in red - just says I can flick switch one position to have both ... nowhere does it say - that is what I always do.

Everyone knows you are a VSR installer / provider ... so no need to insult those who do not wish to have VSR. My and many other boats happily go about their sailing with the 3 way switch ...

Why carry lifejackets, flares, VHF, first aid kit, tools etc etc etc

Same as refueler and anyone else, you're free to us whatever system you choose and to use it however you want. The OP is clearly not entirely satisfied with what he has and want to improve it, i'm proposing a simple solution that makes his charging fully automatic (which is what his aim is) and suggesting a more robust switching arrangement. He's also free to take the suggestion up, or not.

Red bit ... you must be reading different thread then ...

He has proposed his OWN system and his question actually is :

" My question is will the get an excitement current to get going if the output is not to the same battery as the starting current? "

Not exactly same as your understanding .........

I didn't say "always", i said "Whilst you people are motoring around with the switch set to both"

So perhaps it is you that needs to stop reading what is not written.

I install VSRs, FET based splitter, B2Bs, twin alternators and all sorts of other systems and i freely give advice on the installation of all of them, including posting example schematics that no one else in the UK marine industry is prepared to do on these forums, or any other UK forum that i'm aware of. So don't start insinuating that my advice about fitting a system with a VSR is profit motivated, besides, i haven't even suggested a VSR, i simply suggested separate switches.

For the record, i have posted the following schematic more than once:

I cannot be held responsible for your lack of understanding.

The OP is proposing to make changes to his 1-2-B switch system, because he has identifies flaws in the charging method. Hence: "The OP is clearly not entirely satisfied with what he has and want to improve it," I have suggested addition and alternative improvements which would give the OP a better, more robust system that would cost less money than a B2B. I have not suggested that you do the same, so it's really none of your concern what i have said to the OP, stick with whatever you want and leave others to make their own mind up.
 
"Given the antiquated, stick in the mud attitude of some in this thread "

But the difference is : We are not in business to sell systems ...... we are just users quite happy with our old tried and tested systems ..

Second - the comment about motoring around with both batterys paralleled - is that not same as a VSR would do ? Only it does it automatically and to stop it - you would have to operate a switch.

It may interest people to consider how long and why systems are as they are. The 3 way switch was a solution many decades before the introduction of minimum loss relay systems. Until short while later - the alternative was Diodes. We all know where diodes led ... companys sprang up to counter the reduced voltage ... lots of dosh was made.
Along comes the better relays and now we have two 'lossless' systems that both work. Its swings and roundabouts. There is a lot to be said for the Relay route .. I have even fitted a relay to control when my Coolbox kicks in .. so not a matter I am totally unaware of - but my boat is old. To change it would be a major undertaking as previous owners and I have added items over the 40 odd years of her life.

I'm not against modern ways - just don't need it slapped in my face.

????

So you deny he asked a specific question based on his proposed system ? He did not ask for a system .. he asked if the exciter would work ...

Not my misread ...

Which is no use if engine battery goes flat. Simple but vulnerable unless you have bridge switch as I have added (or third battery plus bridge). I know jump leads will do and I wondered why the boat came with them until engine bat went flat on the grid.

No No ... just add a bank of switches and its all tickety boo ....

Yeh right !!

I'll just live with my crappy old system of deciding which battery to use today ..

But he specifically said he doesn't want a Vsr but you still ram it down his throat

In which post was that said? As far as I can see, PaulRainbow has only suggested a revised switching arrangement - it's Refueler who has constantly harped on about VSRs.

OI !!

Harped on ???? Wasn't me that failed to read OP's post properly ...

In fact so far - I seem to be only one who answered his exciter lead question which was his main point based on the system he was proposing to use.

Get facts right ...
 
pvb said:
Yes, you were the first in this thread to mention VSRs, and continued to mention them repeatedly.

Post #5 was in response to post #4 which didn't mention VSR - but the implication was plain ..

In Post #5 - I tried to pre-empt by saying not interested but understood the pros and cons and was not looking to start the age old debate ... but of course some don't care about that.

My harping as you call it - has been defensive. posts. So according to you - I'm not allowed to defend ?

PBO at its best !!

But you're basically the only poster who's mentioned VSRs! Over and over again. That's not defensive, that's provocative.
 
There are bullyboy tactics clearly shown on this thread for all to see. If you aren't in the VSR camp you are derided as a fool. When post get doctored to say somebody is stupid, that isn't acceptable
