Hi all and many thanks to all you lovely! people that bothered to send me a SENSIBLE reply, yes we are making progress, found what most of the switches are for as we have it stored on a site where there is a workshop, just one other thing puzzled us (which we have now sorted) was when we used out water pump(the blue one) on our lunar it didnt shut off when we switched the taps on and off, yet when we tried one that had been left in the lunar it switched them off! apparently they are pressure switches and not micro switches.
