Dont know where to start but here goes.. Went out and refueled yesterday got home locked up did not conect the electric,, (Solar seems to keep all battery`s topped up) .. Went out this morning and the auto step did not come out,, looked at the solar panel read out and all the lights were showing red,, switched on an interior light and hardly a glow,, gathered the batterys were flat,, thought I would start genny,, "No nothing" started the main engine and lights all came on,, step came out and solar started to show a charge.. Stopped engine and back to the first sinario,, "Nothing".. Plugged mains in and everything ok,, solar charging,, plenty of lights,, solar showing (permanent green) which I belive is fully charged batterys. The only thing I did notice,, I had left the reversing camera switched on and it is a big clunky black n white one,, (but a superb camera with long range and wide angle) would this being left on flatten two (2) leisure batterys? But saying that why when plugged into mains does the battery indicator go from red flat and no charge to showing fully charged??? :Sad: I have checked the battery terminals and they are tight and clean,, and on my batterys there is a little round window and on the top of the battery it says if these are green the battery`s are ok.. The only time this has happened before is when I inadvertently left all the "Belly Locker lights on".. which consisted of approx eight (8) fairly large bulbs for approx 16 hours.. oh: Hope I have explained this ok, and would appreciate any help.. :thumb: I am a bit thick when it comes to electrics,, And any thing else really.. Thanks.
