One of my chargers got a little damp ( hot water pipe decided to disconnect ) and is now broken

It is a model mass24/25.

Does only one know of someone who offers a charger repair service ?

Thanks

Jeremy

Ps fuse checked. One gone. Replaced. Pop
 
Probably just wet inside. Take it off, take it apart, dry it out, plug it back in. It might just work.
 
your best option is to asc matservolt in Holland

but I'm afraid that it is not worth the effort of shipping and returning the unit to a qualified repair center
our boat was originally fitted with a very similar unit, and when it broke, it was diagnosed as a uneconomical repair...
 
Goran at NavLab in Palma is your best bet *+34 607 698 344‬. He repairs all makes of nav equipment and also chargers and inverters. If it is water damaged it may be beyond repair, then talk to electro marine also in Palma. They can offer a fixed price repair based on replacing the complete pcb.
 
You'll find Fischer Panda is an official Mastervolt repair company in the UK, and there's a fixed charge to inspect and/or a fixed replacement charge for new.

David Melville is the guy to contact - 01202 820 840. Very, very helpful.

I had a Mastervolt Chargemaster 24/100-3 blow (fail) and David was really helpful. I've thought of changing to Victron but haven't becasue of the positioning, sizing and cabling.

Call David - I don't think you'll be disappointed.
 
I’d buy another because these days they supposed to be smart all “ Carlos Fandangle “ with various stages to extend the bat life and prevent potential bat overcharging.
There’s a lot of chaff on boat forums regarding premature bat life or explosions or both !

So if it did not “ blow “ after a dry out ,then what ?
Just carry on ?
How do you know it’s not lost it’s so called smartness ?

Secondly mount it away from bustable plumbing .
On my boat one side of the ER has plumbing ,hot water tank , water pump ,autopilot pump etc .
Other side is dry and has electronic and electrical stuff .So a water leak will have to span both engines to get the stuff wet ,Further more it’s in a fibreglass hood so,s to protect it from any potential water ingress of the engine room vents in a storm ,heaven beam sea etc just in case moisture enters .


They also decay as they age .
What I mean yours has “ popped “ so zero out put easy to see and deal with .
But say an 80 Ah that’s 10 years old may only give out max 1/2 what it did when new or even less .
I had a 40 which gave out max 3 amps it was 13 years old .
Boat sparky noticed it
Some just give out less and less drop one or two of the so called “ smart “ functions ,ie never bulk only trickle/ float .
So it’s important when it’s switched on to read the amp meter and watch it as goes through it’s various stages ultimately dropping to float in a timely manor .Or learn to understand the flashing LED,s on the unit .

So on balance update and relocate .

i don't know anyone Jeremy but I would replace it. 25 amps charge is pathetically small anyway. I get Porto's point but it is not feasible to relocate in in sq58 e/room so I would leave where is and perhaps renew the 2 or 3 nearby hep2o fittings if they are getting weak.
You might as well get a combi charger and inverter. You can lead the 240v output cable from there to the main port side dinette 230v distribution board and fit the inverter auto relay there because it makes for convenient connection to the boat's ring main and also this location means you will be able to hear the relay click. I can explain how to run the cable but you probably already know. Right above the charger is the hifi box in the saloon.
 
Will follow this up today

This is an additional charger fitted by the prior owner. Fairline don’t charge engine batteries by default ( or didn’t)? I guess he had a flat battery once as this unit only charges the engine start batteries. The main charger is 70 odd amps. As such capacity does not matter much. The charger inverter is a nice idea ( I did not know they made such a thing ) but sadly the wrong set of batteries!

What do you mean "decided to disconnect"? What made it do that?

Incidentally, in case you didn't realise, if you need to replace fittings there are two incarnations of Hep2O fittings. You need the grey "Hepworth" ones, only available on eBay.

Might be worth seeing if the absence of this charger causes you an issue.

They do go Pete .
I had some water under an engine a few years ago .Tasted it not salty just clear water so not antifreeze.
First one thinks over aggressive hosing of the deck above ,small leak or rain etc
Examined quickly the plumbing looked fine at 1st glance in a hot used ER after a run .
Then noticed the water pump occasionally spontaneously pulsing in the night - assumed a tap not turned off fully .
After drying it up noticed every time we came back after a run out more fresh water , this time no rain ,no deck wash - hmm ?
It was a T piece that had fractured on the hot supply under the water heater .The o rings or connections were fine ,it was the actual body which had a fine crack.I guess heat over the years from the hot water in it and hot air temp of the summer ER work hardened it making it more brittle .
It was a simple French eq of B+Q 12 mm fitting ,easy change out I bought a set of various T ,s straights ,elbows etc .

Hold on a minuate
Flew down with no 1 son after his finals for a few days and with 1/2 hr to go all packed “air port ready “ heard a bulge pump fire off hmm ? Never knowingly heard this one ( except deliberate testing ) so lifted a floor panal adjacent a bathroom and saw water running in from the heads .
Turned out an o ring this time on a 12 to 6 reducer for the bedet all easy to access under the vanity unit .
I cannibalised a o ring from one out of my spares pack .
A stressful 20 mins with the clock ticking .

So for me that’s two incidents in 4 years with the blimmimg things - push fit plumbing connectors !

End game is an empty water tank contents bilge pumped out if stuff like this happens while absent .
And any water collateral damage like the OP ,s

Secondly topic of permanent dockside water connection!
One does wonder even with so called pressure regulators etc what would happen if a pipe connect fails ?
Is it possible to chronically over pressure them ? Increasingly becoming susceptible to a failure?
No tank to empty here.
 
one more vote for a charger - invertor,
can you swap your existing charger and use it for the engines ? and buy a new for domestic,

if interested I believe I still have a used Victron Quattro 5Kw a perfect unit for your boat size (we upgraded our 2 x 5Kw to 2 x 8Kw earlyer this year)
all sockets in our boat have 230V permanently

Absolutely nothing, because those of us with a permanent dockside connection are smart enough to fit an overflow safety valve.
Worth 20 quid or so, and allows you to set a limit of continuous water flow anywhere from 5 to 50 litres, after which it stops the flow automatically - hence giving you the peace of mind that you'll never end with more than 50L of fresh water in the bilges.
Of course, theoretically you could fit it also on a plain vanilla circuit pressurized by the onboard water pump, but I've yet to see one single boat fitted with such valve, unless equipped with straight dockside connection.
Therefore, in the event of a leaking hose, the difference between using straight freshwater supply vs. the onboard tank is that with the later you could have as much water as the tank can hold pumped in the bilge, as opposed to just 50L (or less, depending on the valve regulation) with the former. :encouragement:

Ah ok now I get it J. Yes, my 2004 sq58 also had no engine battery charging so I fitted one of the small mastervolt chargers around 25amps. Later big mastervolts have 2 trickle feeds for engine batteries i.e. 3 feeds from one charger unit and fairline fitted those after your build.

As suggested above you could fit an inverter/ charger combi, and demote your existing 70amper to engine battery duty. If you have time on your hands and need to fix a 1st world problem :D
