12v to 24v

12v to 24v

I have been given the task of getting some accelerometers working again. They have been registering 0.03v for 6 months. I traced the cables (all fine) back to the main board. At the top of the board it says 12v supply. I tested using a multimeter and it showed 12v supply. BUT when testing at the bottom of the board I get 24v. There is no centre tapped transformers involved bit I cant figure out why I am getting 24v.

I am trying to impress my new area techs to fix this.
