THANK YOU . Tremendous help. I have had a similar issue with a 5 year old Soft Gloss and my Auto Sentry. Mine was intermittent with the Wash busy signal staying on, so the Auto Sentry would not admit a paid car. I replaced a PIO board on my auto sentry never solving it. Several days would go by working perfectly. I am going to check all my photo eyes for cleanliness and alignment. I know the tire finder eyes have been run over several times .
Thanks
