In that case just remove the silicone from around the parts, take the CDI to a radio/tv techincian, then ask him to test all the resistors and diodes. Then order from Mouser the SCR, capacitor (1.5uf), and project box and any parts that the technician found defective. Then when the parts arrive have the technician install them.
How do I return a part to CDI electronics?
Contact CDI Electronics via website or phone to obtain a return merchandise authorization (RMA) number. Send the part to CDI Electronics with RMA number written on the box. CDI will repair your ignition component, then test the part to make sure it is performing at an optimal level.
How to remove the CDI box from a car?
Your service manual comes in handy at this point as you're supposed to follow precise instructions to remove the CDI box. The automotive should be switched off and allowed to cool. Use an ohmmeter to measure the electrical resistance of the CDI box in a quantifiable way. Different vehicles have specified electrical resistance within the coil.

What are the advantages of a CDI box?
The main advantage of a CDI box is its capacitor's ability to take the shortest time possible to be charged up. Shunt resistance doesn't affect the CDI box due to fast electric voltage rising. Compared to inductive systems, the CDI box system has a shorter transient response and spark duration.
Is CDI repairable?
CDI will repair your ignition component, then test the part to make sure it is performing at an optimal level. CDI Electronics will return the part to you via UPS.
What would cause a CDI to fail?
The CDI goes bad because of different reasons. Some of them go bad because they are old, others experience a wiring short while others go bad because of a faulty charging system.
How do I know if my CDI is broken?
If you are using a digital multimeter then you should hear a beeping sound. Measure for continuity between all the ground and the various other points. If your cdi is working well, you should not hear any sounds. If you do however hear any beeping sound as you are testing, then you cdi is faulty.

Can a bike run without a CDI?
Also asked, can a bike run without a CDI? Yes, you can with a mechanical unit. But customizing one will take lots of time and effort. It might be even more costly to custom build one as the CDI on the market shelf is mass produced one hence efficiently produced.
Can I use a different CDI box?
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.
What is the price of CDI?
2 Wheeler CDI Unit at Rs 300/piece | Motorcycle CDI Unit | ID: 13799074712.
Can a CDI box cause weak spark?
The COIL can give weak spark in spite of the spark being triggered by a CDI box. If you have an anemic yellowy spark from the plug then I would suggest to check that all of the connections are clean and tight.
What's inside a CDI box?
A typical CDI module consists of a small transformer, a charging circuit, a triggering circuit and a main capacitor. First, the system voltage is raised to 250 to 600 volts by a power supply inside the CDI module. Then, the electric current flows to the charging circuit and charges the capacitor.
Will the stator cause no spark?
The stator also performs the extremely important role of generating the power for the spark plugs in the engine. Without a stator, your motorcycle will not get any spark at all as your battery is not capable of supplying the appropriate power levels to generate a spark.
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.

AC CDI & DC CDI
Both usually have same number of connecting port. Only difference is that while AC CDI is directly powered by pickup coil, DC CDI is powered by battery.
Fully faulty CDI unit - symptoms
When CDI unit goes wrong, it is a good thing. Compared to partially faulty one at least.
Partially working CDI unit - symptoms
Wiring short. - This is a simple fix if you can find the exact spot. Sometimes corrosion or a chipped insulation will cause the wires from the pickup coil or to the battery/ignition coil shorting.

Compared to inductive systems, the CDI box system has a shorter transient response and spark duration. Drawbacks of a CID Box.
What is CDI system?
The CDI system produces huge electromagnetic noises that don't sit well with automobile manufacturers. Its short spark duration isn't ideal for lighting relatively lean mixtures. This problem is solved by the release of numerous sparks at low engine speeds. ADVERTISEMENT.
How do you know if your coil is damaged?
Different vehicles have specified electrical resistance within the coil. If the coil's correct resistance levels fail to meet these specifications , you'll know that your coil is damaged. The resistance specifications unique to your vehicle are often found in the service manual.
Why do you need to test a bench?
Because it's able to ignite the air and fuel mixture powering your engine, you need to ensure your bench is free of any flammable liquids like gasoline. You need to test the battery to ensure that it's fully charged else you'll need to replace it.
Can a CDI box generate sparks?
The box can't generate continuous sparks. Thus, it's unable to store enough voltage to keep the engine running. Follow the following directions to effectively bypass your CDI box by carrying out an ignition coil resistance test ("bench test").
Can you bypass a CDI box?
You can temporarily bypass a CDI box for troubleshooting purposes. The box amplifies the small signal generated from the spinning magnet located in front of the pickup coil in the stator, just before top dead center (TDC), when your fuel-air mixture is ignited. The box can't generate continuous sparks.
