People, I need help with a circuit board, I have this device which has been designed by an electronics engineer to an idea of mine, I have had twenty-thirty of these built and sent out, I've had 15% returned mainly through component failure ie, relay or transformer faults, and now when I,m on the point of getting publicity to start things moving I have an earth fault indicating although there isn't a fault, and the chap who did the design has gone on a bender & I can't get hold of him. I've tried to find the fault to no avail,(I should point out that I'm not an electronics engineer) I've cross checked the circuit against the diagram but I think the diagram is not the right one, I have a parts list which again is not 100% correct, the one I've put together shows the same fault. Before I go too far,ie pictures ect,is anyone able to help.
Many thanks,
Barry BazzerEnglander.
