Investigation
The search for where the screw, or perhaps terminal screw, that fell out of the controller should be re-installed ..
Pop off the cover - 4 bolts for the capacitor, 2 more for the DC/DC power supply, and like .. 10 .. for the case to the heat sink.
High voltage side 77
Controller board 78
Beautiful control board. Nicely done Paul! But the control board is not missing any screws.
The capacitors have all fasteners in place. Same with the IGBTs. Look over the heat sink and the case ... nothing missing.
Controller and signals 79
Controller again 80
Current sensors view 1 81
Current sensors view 2 82
Aiming up above current sensors 83
Current sensors last one 84
Go over the case again. I moved the DC/DC converter and .. noticed that there is one screw missing! The home of the offending screw has been found!
