Resistance Mode – if the resistance is low and the reading is zero or close to zero, the test current flows through, and the circuit is continuous. However, if a short circuit exists, the multimeter display will read 1 or OL (open loop), indicating a lack of continuity and an electrical short circuit in the device or circuit you''re measuring.

The sense circuit has a tiny current flowing and, in this case, can be approximated to zero. As there is no current flowing, there is no voltage drop across the sense lead resistance (Ohms law; voltage = resistance x current) so the voltmeter is reading the voltage across the battery impedance only (Battery impedance x test signal …

The dial reading should be 12 volts or more. Work the starter switch, and the reading should fall, but not below 10.5 volts. If the reading does not fall, there is a fault in the ignition-switch circuit or in the solenoid. If the reading falls below 10.5 volts and the starter turns slowly or not at all, the battery is probably flat.
