Forget everything
Literally five minutes after posting my last message I wandered out to the van to see how cold the fridge was (switched it on last night after it being off for 2 weeks whilst at SMG)....
Battery gone from 100% to 40% in 24 hours ...... the "G" and two fingered salute are flashing consecutively in the all new display,
Switch the engine on .... the voltage discharge goes crackers with the engine running ..... -6.2v -3.8v .... -10.5V
and the two pronged salute and "G" continue to flash consecutively with no apparent charging with engine running ....
SMG are taking it back tomorrow morning
I am ever so slightly irritated
