Pixhawk 4 motors wont spin

I have set up pixhawk 4 with ground control and I can arm the controller but the motors will not spin. I have calibrated the escs. I am using hobbywing x rotor escs. Any thoughts?
Regards John

Did the ESCs beep to confirm the calibration? And how did you do the calibration, in QGC?

I did the calibration in qgc but I dont believe they bleeped. I have connected the esc to the power board pm07

Is everything connected correctly? Can you share a picture of your wiring?

I believe its wired correctly. Not sure how I can send a picture will investigate[quote=“JohnM, post:5, topic:12590, full:true”]

Sorry about the delay

Think I’ve sorted it had the pmu connected incorrectly! Many thanks for your help so far. Hopefully I can now progress further!

Where are the ESC signal pins connected to? They should go to those pin headers on the power board.
