Hello my husband and l have a Starcraft and have only had two weekends away in 18 months but we're preparing for a five week trip in September. While away on both weekends my husband mentioned the battery wasn't charging when on power. He didn't think too much about it thinking it was him not understanding the system. We picked the van up from storage a few weekends ago and after days on power the battery is still not charging and the panel reads that it's discharging? Has anyone any suggestions before we take the van into Jayco for them to look at it for us please? Many thanks Karen.
