Here we are testing the voltage drop between the
battery and starter solenoid.
Voltage Drop Testing (Feed Side)
This illustrates a “ground side” voltage drop test.
Remember, there must be a complete circuit for the
system to work. A faulty or corroded ground side
circuit can cause problems as well.
Voltage drop testing can isolate areas in a circuit
where undesirable resistance is present. It is an
important test for both low and high amperage
circuits. See table for maximum voltage readings
when testing circuits.
