Electric Trouble

[tick59]

Our 2006 Elddis 120 is having a bit electric trouble. When we leave home battery fully charged on hookup when we stop leisure battery flat once we connect to hook up or plug our little solar panel in everything works ok except when on hook up fridge does not work on electric and i dont think it work when travelling on battery. When I move the battery switch to vehicle battery it shows nothing and kitchen lights which are remote controll LED come on.Vehicle battery is fully charged and leisure is showing 13.8 before leaving home but only shows 5-10 volts when we park up but as soon as the little solar panel is connected to leisure battery it comes back up to 13.8. fun!!! fun!!! fun!!!

Knackered battery.
Cell open circuit or internal short circuit are most likely cause for sudden failure

Once any kind of charger is applied the battery voltage will increase to the chargers voltage but it wont absorb or hold the charge..
The charger could be the onboard or a solar panel.
