You can diagnose and test the starter motor with basic hand tools, and depending on what you learn, have it running in no time. Place the red lead of a voltmeter on the positive battery terminal and the black lead of the voltmeter on the negative battery terminal to check the battery charge.
A riding lawn mower that has a bad starter can be difficult to diagnose. A bad starter can manifest itself in a cranking noise without engine turnover, a clicking when the ignition button is pressed, or a mower that simply does not respond to attempts to start.
Similarly, how do I know if my lawnmower starter solenoid is bad? First, turn the ignition key to the “On” position. Look for the large terminal posts on the solenoid where the thick red wires connect to the solenoid. Touch the metal shaft of a screwdriver to both of the large terminals at the same time. If the engine turns over and starts, the solenoid is bad and should be replaced.
Simply so, how do you test a starter solenoid on a Briggs and Stratton?
How to Test a Solenoid on a Briggs & Stratton Engine
- Place the engine on a hard, flat surface. To locate the solenoid on the engine, follow the positive (red) wire coming from the battery; it will lead into the solenoid.
- Remove the spark plug wire from the spark plug.
- Keep the negative lead from the voltmeter connected to the negative battery post.
What causes a starter to not engage?
Faulty Starter motor A faulty motor will prevent your starter from engaging. Start by checking the mounting bolts for any loose wires. The grinding noise you hear with the starter is due to a clash between the flywheel and the ring gear. With time these gears get worn out and cause starter, not engaging problems.
Can I bypass my starter solenoid?
Bypass the starter relay Simply put, to overcome and bypass a faulty starter relay or ignition switch, you can touch both the positive starter terminal and the solenoid terminal on the starter using a big screwdriver.
How do you jump a bad starter?
Place the tip of the screwdriver to the post that is connected to the starter motor. The post is usually a large black bolt with a thick battery cable. Next, the metal shaft of the screwdriver should be touching the terminals leading out of the solenoid. You are now ready to start the car.
Can I jump lawn mower with car?
You can jump the mower with the battery in your car or with a portable jump-starter, but you can only use your car battery if your mower has a 12-volt battery. In addition, you can’t use your portable jump-starter to jump a 6-volt battery if it doesn’t have a 6-volt setting.
What does it sound like when a starter is bad?

How do you bypass a starter relay?
How to Bypass the Starter Solenoid Locate the starter motor under the vehicle. Locate the two metal contacts on the back of the starter solenoid. Place the metal blade of an insulated screwdriver across both metal contacts. Get a friend to help you by turning on the ignition with the key. Listen to the starter motor.
What makes a solenoid go bad?
Often, a bad starter solenoid will have the following signs. It indicates a situation where the holding coil of the solenoid keeps holding back, mostly as a result of not enough current reaching the solenoid. It can be caused by loose connections or corroded terminals.
Where is the solenoid on a Briggs and Stratton engine?
The solenoid takes electricity from the battery and converts it to the amount needed for the starter on the Briggs & Stratton engine. The solenoid will be mounted on the frame of the machine between the battery and the starter.
What does it mean when a solenoid clicks?
You may have a bad starter solenoid. The starter solenoid makes a clicking sound once it engages; however, when the clicking continues rapidly, this means the power it’s getting from the battery is not sufficient, which then explains why the engine doesn’t crank when this happens.
