Hi don't know if i'm in the right place as this website has changed and I'm finding it confusing, old age probably, still I have a compass calypso motorhome and my thetford toilet has decided to stop flushing, I've checked the 3 amp fuse and replaced it but no sound of power, took the pump out which is sealed, no joy there, the supply comes from the battery of couse and disapears into a loom, so how do I as a novice check for voltage when i can't even find the wire except at the pump end and that is sealed, it's a bum job but some arse has to do it, I won't use the other puns, but HEL.............P, Please.
