Where is the CDI box located?
Here’s a CDI box in a dirt bike. You’ll often find them lurking under your seat. Andy Greaser photo. The basic CDI system is a trigger mechanism, coils, and a box, often black, with capacitors and other circuitry inside.
Where is the CDI on a Piaggio Zip?
To test it unplug the connector block from the cdi which is found behind the panel which sits behind the rider’s heels (close to the spark plug).
What is a CDI box 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.
Can you bypass a CDI box?
Can a CDI box be bypassed? A capacitor discharge ignition box ( CDI ) box is used in motorcycles, turbine-powered aircraft, outboard motors, and some cars. You can temporarily bypass a CDI box for troubleshooting purposes. Thus, it’s unable to store enough voltage to keep the engine running.
Can I use any CDI unit?
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.
How do I test a CDI with a multimeter?
The connector comes directly from the stator and goes straight to the ignition box or CDI box of your motorbike. After finding the connector, set your multimeter at a resistance of 2k Ohms. Then, take a measurement of the resistance between the white wire to the blue wire.
Does CDI increase speed?
So, if your mechanic has a “better” CDI, it either doesn’t actively limit the max. RPM, or it has a better timing at higher RPM, allowing more power output and hence top speed. Yes, stock CDI limit the power. not every engine of the same model would provide the same horse power.
How do I know if my CDI is AC or DC?
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.
How do I test Piaggio CDI?
First to test the pickup ( CDI red wire) The pickup is located on the side of the flywheel and generates a small voltage everytime a nobble on the flywheel passes it. From the timing of this voltage ‘pulse’ the Piaggio CDI works out when to make the spark. Without this signal the CDI will never spark.

What is inside a CDI unit?
A typical CDI module consists of a small transformer, a charging circuit, a triggering circuit and a main capacitor. Then, the electric current flows to the charging circuit and charges the capacitor. The rectifier inside the charging circuit prevents capacitor discharge before the moment of ignition.
