Understanding the Coolster Mountopz 125cc ATV Wiring Diagram

Now that we have a basic understanding of what a wiring diagram is and the different parts of the Coolster Mountopz 125cc ATV wiring diagram, let’s take a closer look at how it works.

Battery and Ignition Switch

The battery is connected to the ignition switch through a red wire. When the ignition switch is turned on, it completes the circuit and allows current to flow from the battery to the rest of the electrical system.

Starter Motor and CDI Box

When the ignition switch is turned on, it also sends a signal to the CDI box to activate the ignition system. The CDI box controls the timing of the engine and sends a signal to the starter motor to engage and start the engine.

Charging System

The Coolster Mountopz 125cc ATV has a charging system that consists of a rectifier/regulator and stator. The stator generates electricity as the engine runs, and this electricity is sent to the rectifier/regulator to be regulated and converted into the correct voltage to charge the battery.

Lights and Switches

The lights and switches on the Coolster Mountopz 125cc ATV are connected to the electrical system through different colored wires. The headlights are connected to the system through a yellow wire, the brake light through a red wire, and the horn through a blue wire.

Spark Plug and Engine Kill Switch

The spark plug is connected to the CDI box through a green wire. When the CDI box sends a signal to the spark plug, it ignites the fuel mixture in the engine and starts the combustion process.

The engine kill switch is connected to the CDI box through a black wire. When the switch is turned off, it cuts off the signal to the spark plug and stops the engine from running.

Frequently Asked Questions (FAQ)

1. What do I do if my ATV won’t start?

If your Coolster Mountopz 125cc ATV won’t start, the first thing you should check is the battery. Make sure it’s fully charged and the connections are clean and tight. If the battery is fine, check the spark plug and ignition system to make sure they’re functioning properly.

2. What should I do if my headlights aren’t working?

If your ATV’s headlights aren’t working, check the connections and wiring to make sure they’re secure and not damaged. If the connections are fine, check the bulbs to make sure they’re not burnt out. If the bulbs are fine, the problem may be with the CDI box or other electrical components.

3. How do I know if my ATV’s charging system is working?

If you suspect there’s a problem with your ATV’s charging system, you can use a voltmeter to check the voltage output. Start the engine and check the voltage at the battery terminals. The voltage should be between 13.5 and 14.5 volts. If it’s lower than this, there may be a problem with the charging system.

4. Can I replace the CDI box myself?

Replacing the CDI box on your Coolster Mountopz 125cc ATV can be tricky and is best left to a professional mechanic. The CDI box is a critical component of the ignition system, and if it’s not installed correctly, it can cause serious damage to your ATV.

5. Can I use aftermarket electrical components on my ATV?

While aftermarket electrical components may be cheaper than OEM parts, they may not be as reliable or durable. It’s always best to use OEM parts or high-quality aftermarket parts to ensure the safety and reliability of your ATV.
