I have 3 mysterious problems that occurred with my Sterling Europa 460 at the beginning of the season which appeared at first glance to be unconnected but now I am having my doubts.
First of all my Thetford N112 fridge worked intermittently on mains and battery and then stopped, I replaced the main Power supply board and it now works again on Mains (I haven't tried the gas as I do not need it). On battery I am getting a Code 10 error which is something to do with not getting power from the car (how would it, it's not connected to the car) so I am now thinking there must be a wiring problem in the caravan.
My second problem was that the awning light does not work, I have power at the bulb (using a multimeter) and I have cleaned all the terminals and the bulb that I am using (and any others that I have tried) all work OK when connected directly to a battery. Even connecting the 2 leads at the light holder (that clearly have 12 volts at them) directly to the bulb still produces no light.
My third problem is the electric flush on my Thetford toilet which worked intermittently then stopped. New pump fitted, I have full power at the terminal, pump works OK when connected straight to the battery but not when connected to the toilet terminals which have full power.
Telephoned Sterling who said, quite rightly that if there is power going to the units and the units work when connected to another source then logic says that they should work when connected. Well I knew that anyway. Has anybody any ideas why a multimeter says that there is power that the items don't work. I've tried two multimeters by the way to eliminate them. It would seem to me that these items are connected and it must be a problem with the caravan wiring, but where do I start looking. Unfortunately being in Scotland my dealer is a 200 mile round trip so it's not practical to just pop it over to them and anyway I understand a bit about electricity and I am a pretty logical person so I cannot see what is wrong, can anyone shed any light on this for me. All other 12V electrics in the van are working perfectly. Any help gratefully received as I now think I am going mad!!
