Been on a site for a few days now with hookup..but on the second evening lights went out and no power to the 12v system..next day checked for live coming into charger..that was their but nothing coming out of charger...is it better to change the zig charger and at what cost or what do i look for if i strip it down and where can i get the parts...The m/h is a Bessacar e560 on a Fiat Ducato chassie..with 10 months warrenty left...but would the zig unit come under the Swift guarantee seeing as it is in the hab??...Dave
