The Z drive amplifier passed the OHM test per the Haas troubleshooting video. And I tested one of the others to compare response. Same.

I tested the motor to amp cable. It checks out.
The motor test seems kind of odd, but could just be my lack of understanding. The troubleshooting guide says test A.B & C to chassis ground. I don't get a reading on any of the pins in that manner...however...if I take the multi-meter lead on the pin and cross it to the plug housing with the other multi-meter lead to chassis ground I get a reading...however also...if I cross the probe on the pin to the plug housing WITHOUT the other probe grounded, I get no reading...I can't get my head around that just yet.
NVM...that's just ground to ground I think.

Do you know what the procedure is for testing the 6 IC under the board at their solder sites, without de-soldering??
