Yes totally a custom job. Not great at electronics but basically there is a rocker power (on/off) switch inserted into body and grey and red leads connected to it...which makes sense but where as the grey lead is connected and seems secure the ref had disconnected and I can't secure it back in, I can fit it in to plug but it doesn't stay in there (could they be soldered in the switch box?) As even if I fit it back into box and hold it, fit battery I still don't get power??has confused me, could the switch have blown? Cheers for your interest and any help appricated.
