Trouble with 1 output on a EMU Classis

I have been testing all of the outputs on my EMU Classic using a power supply and a circuit test light. I have found all of them to be good but one. The Stepper 1A on pin G2 does not seem to be working. Below is a list of the pin assignments I have made.

Here is a link to a short video demonstrating the issue.

Does anyone have any ideas why I might be having trouble with this one output?

Thanks,
Bruce
