No reading on top line of LYC during Torque test?

It's been ages since I've had an issue w/one of my three wired PTs.. This
one I bought back in '06, not sure what's going on, replace batteries in
hub I have multiple known working LYCs so that's not the problem.

I put the LYC into test mode and the top line of the torque test reads " -
- - "

What's happening here?
