12v not working

[Mr Colpot]

When I unplug the ehu sometimes the ehu light on the control panel doesnt go out and I have no 12v working. It works fine on ehu and also with the engine running.
If I reset the control panel the light is on when I turn it back on. Pilote Explorateur G741.

Is there s fuse in the lead from the hab battery to the electrobloc that has blown.

I'd check the battery.

What’s the voltage of the leisure battery when ehu disconnected. You may need a volt meter to check

 

[Mr Colpot]

Thanks - I have checked the fuses I can see fom the leisure batteries and they are ok. Its intermittent though so I am thinking if its a fuse it would be there (or not there) all the time?

I'd check the battery.

Thanks - have tested both batteries and they appear ok. 12.6v when disconnected or connected.

Charger.... Batteries should show 13v+ on charge even if full.
12.6v off charge and rested.
