I installed the new Home ROM 9.4H today, hoping it would fix the knocker issue. It didn't. There is still no reference to the knocker in any of the Diagnostic menus

Please take a photo of the circled area on the diagram as per my previous post and attach to your post using the Additional Options link - I am pretty convinced that it is the jumpers.
Hi Andrew,
I will take a photo tonight, however I do not understand why "Solenoid 7" is missing from the Test Menu. I would have thought that if the knocker assembly was not working, it would still appear in the Test Menu but not fire during the Run Test mode

Well, my theory is that the machine is jumpered for a European country, where the knocker is by default replaced with a coin counter (whether or not this is actually what happens over there I don't know). So if the ROM is being told it is in Europe, it knows that the knocker isn't there and hence doesn't test it.
I am hoping for your sake that my theory is correct!!
The machine by default is set to United Kingdom. According to the manual, adjustment A.3 21 Coin Meter Units has to be set to anything but OFF to establish the coin unit for a meter attached to the knocker driver and override use of the knocker during awards. However, on my machine that adjustment is set to OFF so I would expect the use of the knocker to NOT be overridden
