Individual Cable

The resistance of any cable can be checked in the same manner by using Rotunda 73 Digital Multimeter 105-R0051 or equivalent.
1. Determine which way the current is flowing in the cable. Connect multimeter positive lead to the end of the cable nearest B+.

NOTE: Prevent the engine from starting by disconnecting the ignition coil.

2. Connect negative lead to the terminal at the other end of the cable.
3. Crank the engine and observe voltmeter. The voltage reading should be 0.2 volt or lower. If the voltage drop is too high, clean the terminal ends. Retest, and if still high, replace the cable.
