How do you test an Arctic Cat CDI box?

How do you test an Arctic Cat CDI box?

Take a 12 volt power source and feed 12 volts onto the Red wire and the Brown wire. Then meter across the wires to the coil from the CDI Box and you should have 24 volts. If you do have 24 volts, put the CDI box in the freezer for 20 min. Take out and retest.

How do you bypass a CDI box on a four wheeler?

Follow the following directions to effectively bypass your CDI box by carrying out an ignition coil resistance test (“bench test”).

1. Clear Your Bench.
2. Remove the CDI Box.
3. Check the Resistance Specifications.
4. Measure the Primary Coil Resistance.
5. Measure the Secondary Coil Resistance.
6. Compare the Readings.

Can a CDI box go bad?

The CDI is not easy to diagnose because the observable symptoms of a faulty CDI box can lead to different directions. Sometimes, a bad CDI does not cause sparks at all. Again, when a CDI box is about to go bad, it can lead to misfires, issues with starting, rough running or even stall the motor.

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. 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.

Can a bad CDI cause no start?

Sometimes, a bad CDI does not cause sparks at all. Again, when a CDI box is about to go bad, it can lead to misfires, issues with starting, rough running or even stall the motor.

What is the purpose of a CDI box?

A CDI or capacitor discharge ignition that is found on most bikes is linked to the ignition where it mainly stores the electrical charge. It is responsible for increasing the spark’s power in the spark plug. CDI box can be found only on vehicles that are based on the gasoline engine.

Are CDI boxes 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.

Can a CDI box cause weak spark?

no ill-will intended here!) when two opinions conflict, it is usually the person saying that a CDI can have a weak spark giving a cursory, almost general-seeming diagnosis, i.e. “yes, cdi’s can give weak sparks.
