Code 7

We have a Wave here that has a Service Code of 7 - SRO... which I cannot seem to fix. When it is in Code 7 fault, the following occurs.
1. In "hands free" on the controls, it makes no difference. Code 7 still errors.
2. If I short out the foot pads it does not fix it.
3. The gate switches are working.
4. There is no voltage at the foot pad terminals. Normally 24V. What stops the 24V at this point?
5. There is 24 Volts at the base platform switch terminal and on the platform terminal block.
6. The horn still works. So I am guessing ED-8 contact is closed.
7. The gate siren still works.
There is something else, somewhere on the machine that makes Code 7 error, but I cannot see it. Any help will be appreciated.

A pinched wire and some bad crimps on a cable termination modification to the machine caused the fault.
