Fuse Box

[NICKROGER]

We have just arrived on site and were having problems with the water pump. Having changed the fuse and altered the pressure switch water is now on. However the fuse box is buzzing, tried turning the pump off but fuse box is still buzzing. Switched main off and back on buzzing stopped for 1 minute and then started again.

Is the m/home new to you or has it been O.K. without any buzzing in the past?
Is the fuse gripped firmly in its holder? If not, the buzzing could be arcing between the fuse legs and its holder.

Try changing the fuse again.

More likely to be a relay.

Aare you sure its the 12v fusebox, it could be the charger if theyre close together..
If it is the fuse box it could be a loose wire to one of the terminals.
Tale the cover off and check all screws for tightness. If left it could cause a fire.

The EHU is plugged in but is flashing, leisure battery now down to 7 and displaying as low on main screen

Tried that still buzzing. Hook up sign keeps flashing taking source from leisure battery which is now very low at 7

At 7v it's more than 'low'; it's stuffed and likely to need replacing. The buzzing could be a relay which is getting insufficient volts from the leisure battery to hold it in the changeover position.
Since the EHU indicator is flashing it seems to me that the initial fault lies with the lack of a 230v supply.

Either that or the mains battery charger is knackered.
