I have one of these units fitted to my Boat and I need to maintain it .
I have emailed Walkers , now taken over by Lilley & Gillie but they proved
to be no help whatsoever , saying that the unit had been discontinued for
some years. So has anyone a copy of the operating instructions or better
still a circuit diagram they could email to me ? this would make my task so
much easier.

Thanks Philip
