To start testing your starter motor, you'll need a multimeter - think of it like a Swiss Army knife for electrical measurements. Make sure it's set to DC voltage mode, and then connect the probes to the starter motor's terminals. It's like plugging in a puzzle piece - the multimeter will give you the readings you need to diagnose the problem.
Now, you might be wondering what to expect when you take your first reading. Will the voltage be sky-high, or will it be lower than expected? The answer lies in the specifications of your starter motor - check your car's manual or the manufacturer's website to find out what the recommended voltage should be.
