Hello Dora is nearly 2 years old. We love her. But ... she’s had 3 batteries and at Christmas a new alternator. The battery drain in the winter is crazy. I start her up every 2 -3 weeks. The dealer said flick the isolator switch- done.it was flat before Xmas and we were using her for Boxing Day ( until lockdown changed ) and No Renault garage could take her as she’s too big. So paid a garage to repair her- they said alternator was burnt out and dangerous. New one fitted. 1 month later she’s flat again. Now booked into a Renault garage I have found that will take her- this week - once we get the break down guys to get her going. Motorhome garage say it must be the Renault engine. I don’t understand engines just frightened of a huge Bill. She is a Luna who went bust so no habitation warranty!!
