It all depends how the boat has been wired. I hope the battery charger output has been wired so that you can leave the charging on but with the rest of the 12v electrics isolated but it may not be. You will have to check. I am also concerned that your fridge circuit does not have its own on/off switch. It may be a good idea to trip your 240 volt system mcb/rcb before you connect the shoreline so the mains circuit is isolated from the inverter. However again it depends upon how the mains part is wired. One other thing. I fully agree with leaving the charger on BUT do not do it if any battery is showing signs of needing frequent topping up. This could indicates a faulty battery and if it is left charging until the cell goes dry the battery just might explode. Its very rare but not worth risking. Tony Brooks

Tony, I have a similar issue, how do I check the cicuit, as I don't have a wiring diagram, for that part of the circuit. Duncan

I can not risk you killing yourself by trying to following advice about testing the mains side of things so I can only answer for the battery charging bit. Engine off. Land line off. master switches OPEN. Put voltmeter across the battery and it should read 12.8 volts or less as long as you have let the batteries stand for several hours or used them. Turn shoreline on. If the voltage stays the same then the master switch is isolating the charger from the batteries. If it rises then the charger is connected directly and not via the master switch.
