Measuring Voltage Drop - Step by Step
The step by step method is most useful for isolating excessive drops in low voltage systems (such as those in Computer Controlled Systems").
Circuits in the Computer Controlled System" operate on very low amperage.
The (Computer Controlled) system operations can be adversely affected by any variation in resistance in the system. Such resistance variation may be
caused by poor connection improper installation improper wire gauge or corrosion.
The step by step voltage drop test can identify a component or wire with too much resistance.
