Use Cable Drop test to determine if there are worn cables or bad connections between the battery and the alternator or starter.
At any time during the test tap left arrow to return to the previous screen.
Worn cables and bad connections create resistance, causing a voltage drop across the circuit. This drop reduces current carrying capability, creating the same symptoms as a weak alternator or starter, as well as causing premature battery failure.
A signal is sent through the circuit to the component under test. The voltage drop on both sides of the circuit as well as the total voltage drop are simultaneously calculated.
