hey there,we are pamela,steve n ella from walsall.we have recently brought a 1989 hymer camp 56 on a peugeot chassis. so far we have replaced the head gasket,then next we moved on to the hab area.we have had a new battery and charger on. we have got the fridge working on 12 & 240v but not gas.perhaps the ignitor?? the heating is gas only and needed just an ignitor and the vents blow fine. the water is doing zilch!it is a gas only 10lt trumer boiler.there are no red or green light on the control panel.maybe the pc board?? also i cannot find the yellow open/shut valve that should be near the boiler....is this normal??perhaps due to its age?? the thetford works ok apart from the flush.it only manages to was half the bowl.any ideas?? any help and advice would be very welcome.
