How It Works. The starter solenoid is a small magnetic device located inside the starter motor. When you turn the ignition key on in the “start” position, the battery sends a small electrical charge to the starter solenoid. … The starter motor shaft begins to rotate and engage the teeth of the flywheel.
How does a riding lawn mower starter work?
Most large Kohler engines on riding lawn mowers use an electric starting system. Part of that system is a starter solenoid. The cylindrical solenoid is a low-amperage relay that safely completes the high-amperage electrical connection between the battery and starter motor when the ignition key is turned.
How does a tractor starter work?
A starter motor spins (rotates) the engine via a small pinion or gear wheel, which connects with the flywheel via a large gear ring. The starter motor is initiated by the ignition key. … The electromagnet attracts an iron rod closing two contact points completing the circuit between the tractor battery and starter.
How do I know if my lawn tractor starter is bad?
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. An indication of a bad starter motor is the absence of other electrical problems that can be more easily tested.
How do you start a riding lawn mower with a bad starter?
Attach a jumper cable from the large lug where the engine starter cable and other lugs connect to the battery cable. Finally, rotate the ignition keys of the lawn mower. If it just clicks without starting the lawn mower, you may need to replace the solenoid.
What wires go to a starter motor?
The negative (ground) cable connects the negative “-” battery terminal to the engine cylinder block, or transmission, close to the starter. The positive cable connects the positive “+” battery terminal to the starter solenoid. Often, a poor connection at one of the battery cables can cause the starter motor not to run.
Can you fix a starter solenoid?
Sometimes the high-voltage contacts inside the solenoid can burn, carbon-up or stick, resulting in a no-start condition. Replacing the starter solenoid with a new starter does not always have to be done. The solenoid lends itself to repair just like any other component, and savings can be realized by doing so.
How do you test a starter solenoid on a riding lawn mower?
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.
Why is my lawn mower starter smoking?
Your lawn mower’s carburetor regulates the ratio of gasoline to air mixture. If the carburetor isn’t getting enough air, the mixture has a higher percentage of gasoline, which can create black exhaust smoke. It’s possible that a dirty or clogged air filter is preventing sufficient airflow into the carburetor.
What are the symptoms of a bad starter solenoid?
Consider these possible signs of a failing or bad starter solenoid when you turn the key:
- Nothing happens. …
- A single “click” sound comes from the engine compartment or from under the car. …
- Repeated “clicking” sounds usually indicate a dead battery.
