Roland,=0A=0AI installed mbmon, it looks like its a great application, but = I have a question, I google it and I found no answers yet.=0AWith mbmon -r = what values do you get?

Do you have any idea?=0A=0ATools like m= bmon can show you the different voltages that the power supply=0Aproduces. = But current isn't measured in the different circuits, AFAIK.
