You can bypass a capacitor-discharge ignition (CDI) box temporarily for troubleshooting purposes. Since a CDI box transmits voltage from the pick-up coil in the stator to the ignition coil and does not generate continuous sparks, it cannot store enough voltage to keep the engine running.Know More
Since a CDI box ignites the air and fuel mixture that powers your engine, clear your work area of all flammable liquids, such as gasoline. Keep a fire extinguisher nearby.
Test the battery to verify it is fully charged. Replace it if necessary.
Locate a black box with two plugs and a bullet connector. A pin connects to the pick-up coil in the stator, and another pin connects to the ignition coil, which sends the spark to the spark plug.
Ground the wire coming from the stator to the motor.
Disconnect the main wires coming from the CDI box.
Attach a jumper wire from the positive battery terminal to the positive wire on the ignition coil. Attach a jumper wire from the negative battery terminal to a ground.
If the engine sparks, you have confirmed a failed CPI box. If the engine does not spark, your problem is not a faulty CPI box.
A CDI box can be tested using a device called an ohm meter, which measures electrical resistance. The ohm meter can be attached to either input or export wires, ensuring that the CDI box is both receiving power and transmitting it.Full Answer >
A capacitor discharge ignition or CDI works by passing an electrical current over a circuit capacitor. This type of ignition builds up charge quickly. It is ideal for smaller vehicles and motors.Full Answer >
Displacement is what makes boats float. Displacement was discovered by Archimedes, and the Archimedes Principle is also used to describe the theory of displacement.Full Answer >
Understanding the different aspects of tractor horsepower is the first step to comparing this selection criterion. There are three main types of horsepower that need to be assessed when making comparisons: gross horsepower, PTO horsepower, and drawbar horsepower, as indicated on Hobby Farms.Full Answer >
