How To Test A Starter With A Multimeter
To test a starter with a multimeter, you will need to perform a voltage drop test. Here’s how:
- Disconnect the battery cables from the starter.
- Set the multimeter to measure DC voltage.
- Connect the multimeter probes to the positive cable and the starter solenoid input terminal.
- Turn the key to the start position and measure the voltage. The voltage should drop slightly, but not below 9 volts. If the voltage drop is too low, it may indicate a problem with the starter solenoid or the battery cables.
- Next, connect one multimeter probe to the positive cable and the other probe to the starter motor housing. This measures the voltage drop across the starter motor. The voltage drop should be less than one volt. If the voltage drop is higher, it may indicate a problem with the starter motor windings or the connections.
- Finally, connect one multimeter probe to the negative battery terminal and the other probe to the starter motor housing. This measures the resistance of the starter motor windings. The resistance should be less than one ohm. If the resistance is higher, it may indicate a problem with the starter motor windings.
Note: Before performing any electrical tests on a starter or any other component, make sure to disconnect the battery cables to avoid any electrical shock or damage to the multimeter.
