Battery Cable: Testing and Inspection
A voltage drop test will determine if there is excessive resistance in the battery cable terminal connections or the battery cables. If excessive resistance is
found in the battery cable connections, the connection point should be disassembled, cleaned of all corrosion or foreign material, then reassembled.
Following reassembly, check the voltage drop for the battery cable connection and the battery cable again to confirm repair.
When performing the voltage drop test, it is important to remember that the voltage drop is giving an indication of the resistance between the two points
at which the voltmeter probes are attached.
EXAMPLE: When testing the resistance of the battery positive cable, touch the voltmeter leads to the battery positive cable terminal clamp and to the
battery positive cable eyelet terminal at the starter solenoid B(+) terminal stud. If you probe the battery positive terminal post and the battery positive
cable eyelet terminal at the starter solenoid B(+) terminal stud, you are reading the combined voltage drop in the battery positive cable terminal
clamp-to-terminal post connection and the battery positive cable.
