Hi Bob Many thanks for your quick reply. I realise that the size of the wiring comes into it but I was working on the assumption that the electronic specialists amongst us would know what wiring the manufacturers usually use for this applications.
BTW, I’m not blaming the wiring, I just need to arrive at a realistic figure for the offset in my LX 9000.
