When it comes to diagnosing starter problems on your 110cc ATV, the solenoid is often the culprit. The starter solenoid is an electromechanical switch that engages the starter motor when you turn the key in the ignition. If your ATV won’t start, it may be due to a faulty solenoid or a wiring problem. In this article, we’ll provide an overview of 110cc ATV starter solenoid wiring, including a wiring diagram, troubleshooting tips, and frequently asked questions.
Understanding the Starter Solenoid
The starter solenoid consists of two main components: a winding coil and a movable plunger. When you turn the ignition key, a small current flows through the coil, which generates a magnetic field. The magnetic field then pulls the plunger towards the coil, completing the circuit and engaging the starter motor. When you release the key, the magnetic field collapses, and the plunger returns to its original position, disconnecting the circuit and stopping the starter motor.
The solenoid is located on the starter motor and is connected to the battery, starter motor, and ignition switch. A wiring problem in any of these components can prevent the solenoid from working properly, resulting in a no-start condition.

The above wiring diagram applies to most 110cc ATV models, including TaoTao, Coolster, and Peace Sports. However, it’s important to check your ATV’s user manual or contact the manufacturer to confirm the correct wiring for your specific model.
Troubleshooting the Starter Solenoid
If your ATV won’t start or makes a clicking sound when you turn the key, there may be an issue with the starter solenoid. Here are some troubleshooting tips:
Check the Battery
A weak or dead battery can prevent the solenoid from receiving enough power to engage the starter motor. Use a multimeter to test the battery voltage. If the voltage is below 12 volts, recharge or replace the battery.
Inspect the Wiring
Check the wiring connections between the battery, solenoid, starter motor, and ignition switch. Look for loose, corroded, or damaged wires. Tighten loose connections and replace any damaged wires.
Test the Solenoid
Use a multimeter to test the continuity of the solenoid coil. Set the multimeter to the resistance setting and touch the probes to the two small terminals on the solenoid. The resistance should be between 10 and 20 ohms. If the resistance is outside of this range, replace the solenoid.
FAQ
What is a starter solenoid?
A starter solenoid is an electromechanical switch that engages the starter motor when you turn the key in the ignition. It’s located on the starter motor and is connected to the battery, starter motor, and ignition switch.
How do I test a starter solenoid?
Use a multimeter to test the continuity of the solenoid coil. Set the multimeter to the resistance setting and touch the probes to the two small terminals on the solenoid. The resistance should be between 10 and 20 ohms. If the resistance is outside of this range, replace the solenoid.
What can cause a starter solenoid to fail?
A starter solenoid can fail due to a wiring problem, a weak or dead battery, or a faulty solenoid coil. It may also fail due to wear and tear over time.
Can I replace a starter solenoid myself?
Yes, replacing a starter solenoid is a relatively simple task that can be done with basic tools. However, if you’re not comfortable working on your ATV’s electrical system, it’s best to have a professional mechanic do the job.
Can a bad starter solenoid drain a battery?
Yes, a bad starter solenoid can cause a parasitic draw on the battery, which can drain the battery over time. This is why it’s important to diagnose and fix solenoid problems as soon as possible.
By following the wiring diagram and troubleshooting tips in this article, you should be able to diagnose and fix starter solenoid problems on your 110cc ATV. If you’re still having issues, consult your ATV’s user manual or contact the manufacturer for further assistance.
