Correction, because I didn't see the phase detect "Pass" light come on I did not attempt to power up the machine. I have the E-stop off but did not attempt to push the power on button at the pendant.
I pulled the power board PCB and am examine for broken soldier or burnt up components, none noted.
I did a continuity test on the Phase detect "Pass" light and am seeing an open across the bulb, not sure if this is an LED or some sort of compact bulb. I switch the leads around and read open across the bulb. Other than that I see nothing else out of the ordinary.
Anyone have any idea if this is a bulb or LED? If I get brave enough I may desolder it and get a closer look. Not sure if this is enough to hold me up.
If I were to power up the machine with it wire out of phase would it say something on the startup screen on the pendant?
