For the OCP mods, measure the basic resistance across each capacitor (the components next to the red ones in the first pic you posted) and solder a resistor of equal or slightly larger value in parallel. This will increase your OCP limit significantly


The 2nd pic with the red circle..... Thats the mod point for the vCore but I have NO idea why the wire is going to a diode. It should go to a 1K trimmer (other end connected to ground)... nice and simple
