Hi All.
so very strange thing happened the other day in that i thought i would give it another go and try starting the wash on the inverter and then plugging in the genny so that it can charge the batteries at the same time ( i have done this maybe 15 times before but every time i put the genny in the loop the circuit cuts and the machine door lock lights go out and it stops)
well this time it worked ( using a new Hyundai genny ) so i thought id try it on the honda as well and yep it works too.
so essentially i have a work around but its nothing that i havent tried before.
so still a mystery but a good one now rather than a frustrating one.
thanks for all your advice and help along this very odd journey
