Voltage drop testing is indeed the best method for locating high resistances in a cranking circuit because it allows for the measurement of voltage loss in the circuit under load, which is when the high resistance would have the most impact. Using an ohmmeter to measure resistance in a cable can be misleading because it does not account for the circuit's behavior under load.
