Thanks for the link to the old post Mackrackit.I felt alot better after knowing at least there are others out there that have grappled with this kind of application.It was encouraging to see somone on that post mention that it would be great use optical sensors,which I have.
By the way I just tried to stick a couple of pictures of the distributor and its sensors up but when I click the attachments button above I just get error on page.Any Ideas?
Thanks Again for your thoughts
O.T.
