No working lights or toilet flush, but working plugs and fridge

[cerihandley1]

Hi, can anyone help please,
I’ve just had fitted a new car battery and new leisure battery yesterday. The fridge. Air in and plug sockets work but we have no lights working at all.

We’ve tested the fuses and all looks ok. Anyone know why lights and toilet don’t work and what could this be and how we rectify it please?

Would help if you said make & model of an, same distribution unit & control panel.

The fridge and sockets will be on the mains but the lights and toilet flush on the 12v circuit.
Has the 12v master switch been turned of and not on again?

Is the main fuse near to the leisure battery positive connection ok ?

Have you selected the battery on the rocker switch (assuming there is one) - middle setting is 'off' .

There is a thick wire that feeds power from the leisure battery to the distribution/fusebox. On that wire, very near the leisure battery, will be a big fuse, probably 30A or 50A. If that blows, none of the 12V circuits (lights, water pump, flush etc) will work. It's easy to blow that fuse while fitting a new battery.

There are other possibilities if that fuse is good. What make/model is the distribution/fusebox?

When you say the sockets work, Is that the 3-pin 240V sockets or the 12V sockets?
