Coachman 560/4 battery - Coachman won't help
We have a coachaman 560/4 2011 model bought from new and since we got it the battery is being totally flattened when not on hook up when nothing is switched on. The last instance was when it was sitting on the dealer's yard with everything switched off
and a brand new fully charged battery, 10 days later the battery was totally flat. We have had several new batteries the last given by the dealer to get us going after the last flattening. The dealer has looked into this several times but can't find the
problem although they have obviously seen it and Coachman's only response is to say it looks like a wiring/poor battery issue and that I should refer it back to the dealer, really useful that! Its obvious that his van has a problem and we have to be able
to use it away from hook up but the dealer can't find the problem and it seems the manufacturer/designer refuses to help. Someone has suggested the alarm battery may be charging itself from the main battery but that would not drain a full 110AH battery in
just 10 days. Ideas and suggestions welcome please.
