Hi
Just an update.

The customer had bypassed the seat switch after informing him this was one of the suggestions. My only concern was that with the seat disconnected it always came up with an operator error of some sort, however Since then he has not complained. Its been 3 days so far without fail :)...then again sometimes it went weeks..we will have to wait and see.

Thank you for all the pointers and advice, much appreciated.
Regards
