1986 QT-10N Tool Setter Beep

I've got a 1986 QT-10N, 20 HP, 12 position turret with the tailbody (universal). When the tool setter extends on the tool measure command, it does not beep. it also does not enter a value when you touch off on it.

A little background on the machine, I bought it with a dead battery and dubious parameters. I replaced the battery and at that time, the tool setter beeped when it would extend.

I now have a clean set of parameters in the machine that came direct from Japan, with my serial number on the sheet (so I'm reasonably confident in them). Is it possible that one of the parameters pertaining to the tool eye is incorrect?

Aside from the tool setter business, I'm also seeing that parameters M28-M31 cannot be set to 0 (as the parameter sheet shows they should be). I can set them to any other number but 0, actually. When I enter 0, I get a blue "insufficient data" error in the corner of the screen.

I posted my parameters for reference to the question but also in case someone else needs them on the forum, I'd have loved to come across these with just a search.

It just occurred to me as I'm writing this that I may not be getting voltage to the tool eye. The LED never has lit, I pulled it today and did not get continuity across the two pins on the plug (like one of the switches was open). When I opened the top of the unit to expose the LED, I did not get continuity across the LED, nor did it light with external DC power. I bypassed and connected the wires going to the LED and the tool eye showed continuity across the plug pins. Pressing any of the 4 tool buttons would break this continuity, so I figured that was my smoking gun (it never is when you're that sure). I will read voltage coming from the female/machine side of the plug and post up.

Thanks
