Even if you don t have an electrical schematic of the circuit board which would identify components and give you the voltage and resistor values that should be present many circuit boards have test points that are clearly labeled.

They attenuate the voltage so that it is proportionate to the current. Disconnect the power supply from the circuit board. A test of circuit board components such as capacitors resistors transistors and integrated circuits can be done to some extent without removing the components from the circuit board.
