I have recently returned from holiday during which I have had issues with the Sargent control panel and the main power unit, essentially they switching off on their own from time to time. Sometimes it would reset using the shutdown button on the control unit and sometimes not. I tried taking out both battery fuses and it did reset but then the problem started again. I read somewhere that it could be an earth cable problem and so I have added a second earth strap which is, at present, working but i'm not that confident it has resolved the issue. Any ideas or similar experiences ?
