How do you find out if you moped is DC or AC?

If you turn the key on and your headlights come on, your scooter is DC, if you have to start your scooter and have it running to get your Headlights to come on your scooter is AC.

How do I know if I have AC or DC CDI?

Your CDI has two plugs, a 4-pin and a 2-pin. The 4-pin side may have 3 or 4 wires connected to it (both AC and DC versions). If the 2-pin connector has only 1 wire going to it, it's a DC CDI. If there are 2 wires attached to the 2-pin connector, then it's an AC CDI.

Do mopeds have AC?

The power generator on a moped is producing AC current with a permanent magnet, or fixed field alternator. The alternator is composed of the stator and the flywheel. ... Most flywheels have 4 or more magnets, most generally in multiples of 2.

What is AC and DC CDI?

The AC-CDI ignition system is the most common CDI in small engines. The module gets its power solely from the alternator in form of alternating current. DC-CDI. This kind of CDI is powered by a battery. The system comes with a DC/AC inverter circuit to raise the voltage from the 12V DC up to 400-600 V DC.

Are Chinese scooters AC or DC?

Many scooters with chinese 2 or 4 stroke engines are mounted with different types of CDI. They are either AC type : Alternating current or DC type : Direct current. To find an unlimited CDI, you must first identify the type of ignition you have. The easiest way is to do this, engine running, with an electric tester.

What is a stator on a moped?

Simply put, a stator works together with a rectifier regulator to accomplish the same outcome as an alternator—to generate the DC power required to operate the motorcycle, ATV, side-by-side, etc. The stator is the coil of wire housed inside the engine case.

What does a rectifier do on a scooter?

The rectifier regulator converts AC power to DC allowing the alternator to charge the battery, and controls the amount of power delivered to the battery.

Is a Kymco Agility 50 AC or DC?

The capacitor discharge ignition (CDI module) or ignitors used on KYMCO gas scooters are unique in that they are direct-current (DC) units, as opposed to the AC modules found on most other scooter brands. If you are a KYMCO owner you know how finding these parts can be a frustrating and often difficult process.

How does a DC CDI work?

Working Principle of a CDI System. A capacitor discharge ignition works by passing an electrical current over a capacitor. This type of ignition builds up a charge quickly. A CDI ignition starts by generating a charge and storing it up before sending it out to the spark plug in order to ignite the engine.

Are CDI interchangeable?

Because ignition characteristics (particularly timing) vary widely across vehicle models, there's no one CDI box that can cover them all. The CDI must be matched to the engine that's being worked on. ... The CDI boxes in these systems are not interchangeable.

What is AC-CDI?

AC-CDI. The AC-CDI module obtains its electricity source solely from the alternating current produced by the alternator. The AC-CDI system is the most basic CDI system which is widely used in small engines. ... This DC current flowed through a wire to an ignition coil mounted outside of the engine.

What does a CDI box do on a scooter?

The CDI is like a computer as it controls the engine of your scooter. It instructs the fuel injectors when and for how long they should spray. It also directs the spark plugs on how to perform especially when they have to fire.
