Will do. I am a bit worried about the smaller 45a alternator.

This is really helpful my battery bank is lithium, so it will pull everything it can get from the alternators. Just tested it at 2000rpm and getting 100amp total from both alternators which is what I was originally expecting. I have ordered a clamp meter so I can measure them separately.

Found the power curve chart for my alternator. Need to do a few tests to see if this is what happens in real life. I have bonded both my 95a alternator and 45a alternator to charge my battery bank and am getting 40amp from both at 1000rpm which confused me as I expected more from the 95a alternator. However this power chart seems to match this. I'll try increasing the rpm next and see if I can get more out of the 95a alternator.

Replaced the prv, and that seems to have fixed the problem. Many thanks for all your great help again... I'll reposition the water pump with flexible hose another day, might add one of those water gauges at the same time...:)

Anything I need to know about changing it? Do I need to empty the tank? I assume I need to make sure the pressure is released from the system at least ?

Prv should be 43psi Water pump should be 30psi ish. Not sure adjusting the water pump is going to make much difference? It's looking like a faulty prv ?

This is the prv

Not easy to get to it. I'll look up where the screw is online and see if I can find a way of getting to it. I have turned the water pump on whilst watching the outlet in the bilge, and it starts to seep just as the water pump gets up to its cutout. Seems that it's either a faulty prv or the water pump cut out is too high. Any other possibilities?

This is the water pump.

Yes there is an accumulator next to the water pump. I will check if the pump has any labelling and if it has its own pressure valve. Is there a standard setting for the prv at which it releases pressure ?

It's under the bed with easy access. The water pump looks newish as well. Could they have installed a water pump that is a higher pressure than the one they replaced? Or is there a way to check the correct pressure to see if it's the water pump overpressurising or a faulty prv?

I turned it to see if it was working, and it made a gushing noise for water flowing through it. But can't tell if water is coming out of there. Guess it has to be if there is only one flow into the bilge from the calorifier?

My water pump has been operating every 10 mins or so even when no taps are on. Can't find any obvious leaks and the leaky kitchen tap is just a drip so not that. Took a closer look in the stern bilge and far too much water there. Put a bowl under the stern gland and water not coming from there. Tucked up behind the engine though there is the hot water flow and return from the engine to the calorifier and another outlet hole which is pushing out hot water. So, it looks like hot water is coming out of the calorifier and into my bilge (and a lot of it). Any great ideas for what is causing this? Thanks.

I have emailed Beta and see if they can help with this - good idea

Hmm, so my best approach is a very efficient compressor fridge so that the compressor doesn't kick in very often overnight when the door remains shut ? The current one is on about 30% of the time when the door remains shut. Is that normal ?
