have found and killed another fault that even one of AMF UK's senior technicians couldnt cure, it has vexed 3 of our regional techs and several other centres cheif techs for 2 years. and my chief charged me with the job of finding the fault at all costs! (took me a good day)
here is the scenario:
If the mask cable is connected to the chassis, the mechine cocks-up and starts to do strange things like going thru strike cycle on every throw and cycling on its own, unplug the mask cable and bridge the switch pins, fault dissapears, the fault stays with the machine, dosent follow chassies about at all and does it with every chassis installed on the offending machines.
heres some info:
we have MENDES masks with ball 1 and 2 lights and a mask switch only, no other electrics on them whatsoever.
we have c series '70s with MP chassies and Qubica
we have NO managment control box
we are in the UK and on 240v (3 seperate phases to neutral across machines)
100 points for the person that figures it out!
i GUARANTEE its not the first thing people say!
enjoy, ill post the problem shortly.
