What are the problems with a 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.
How can I tell if my CDI box is damaged?
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. If the coil’s correct resistance levels fail to meet these specifications, you’ll know that your coil is damaged.
