OVD is output from H-class step driver, and there is MV or HV when mosfets off/on, that output going to fuse, same as H900 with different step driver. In H900 MV going to comutation diode not to fuse.

Hi Apex,
Per your schematic in post #402 +HV -HV goes to amp should it not go to the PS together with the +MV & -MV only the 0VD should go to the amp as the HV & MV should appear on it as it is switch by the controller.
