If you are using a digital meter then you should have a reading of 0 or 0.0 If you don't get anything, your meter will display a 1. A 1 indicates a bad fuse. If you are using an analog meter the needle will move towards 0. If it doesn't move the fuse is bad. It would be unuasual for both the touchpad and control board to fail at the same time. I have seen it happen before but it's very rare.
