Check the number switches of keyboard - The second bank of wipers on the keyboard numbers. I think you have a problem with wiper that connects #4 to #5. There should be continuity on two rows of the number switches. You only have one that is complete, the other row has an issue.
I have an image that may help may that you can find here:

Note the circled contacts on the Keyboard Selector - pretty sure this is the problem area.
