Our MH sits at home on ehu nearly all of the time, except in sunny type weather when I let the solar panel do a bit of work. It has the Sargent smart charging system fitted which automatically senses which battery to top up and can be left switched on.
Nothing is left switched on except in cold weather when a separate thermostat controlled heater keeps the damp and chill at bay.
This has been the normal procedure for the last three and a bit years with no problems.
Last Friday I was going down to Gloucestershire for the weekend and was all packed up and ready to go. Turned the key and the battery was flat.
This took me by surprise as I had only been running the engine the day before.
I jump started it, thinking that a good drive down the country would charge the battery back up.
The engine was not switched off until we were parked up and in position. We were then back on ehu and thought we would be ok.
To cut a long story short, it wouldn't start on Sunday morning and had to be jumped off again.
Same procedure on the way home, ie not switched off again until parked up.
I immediately tried to start the engine but the battery was flat.
The leisure batteries have been fine, which could be down to the solar panel keeping them right.
I did notice that during the day the control panel showed that the vehicle battery was topped up, but in the morning it was showing 11.6 volts. Solar panel trying to charge a dead battery ?
I now have the vehicle battery on charge from a separate charger and will have to give it a while and see if it holds it's charge.
If it doesn't then it would indicate a new battery is required.
If it does hold it's charge then I would have to think that it is the on board charger that is at fault. I have checked all the fuses that I can find after consulting the Fiat and Autotrail handbooks
Sorry to be so long winded, but I was trying to give as much info as possible.
All advice will be gratefully received.
