ok just got back from holiday with my sterling europa 620 and whilst we were out there had a lightening storm we got back to find the fusebox had triped put it back on and then a couple of days later my leisure battery went flat but it was indicating green which means fully charged the guy at arosa campsite charged it for me but when i put it back on the caravan it works but will not charge with the built in charger so im wondering if it will be the battery that has gone or has the trickle charger on the van gone as all lights are on on the fusebox and i cannot see any fuses blown
please help me
