How To Voltage Drop Test A Starter. A voltage drop test will assess voltage losses at the battery the alternator and the starter. Now think about how we use a multimeter for voltage drop measurements on a starter motor positive cable connecting the signal lead and ground lead to either end of the starter cable and operating the starter motor both test leads are above 0 V.
This test will show you how to quickly pinpoint the source of the draw using voltage drop across fuses. How to test troubleshoot check a starter for correct operation. The basics of a voltage drop measurement where both probes of the meter are placed on the same side of the circuit here shown between the positive battery terminal and the positive post on the starter solenoid.
If there is no voltage drop in the cable the voltage at the terminal on the starter solenoid will be same as it is at the positive.
The test in this video is being performed on a Honda CR-V. How to test troubleshoot check a starter for correct operation. The basics of a voltage drop measurement where both probes of the meter are placed on the same side of the circuit here shown between the positive battery terminal and the positive post on the starter solenoid. Using this method prevents the vehicle from waking up during the test causing you to have to start over from sleep mode.
