How much power should be coming out of a cdi box i have 116 volts going into my ignition coil from the cdi box on my yamaha atv but there is no spark out of the coil is this not enough pwr?

Typically, a CDI (Capacitor Discharge Ignition) box generates a high voltage output to the ignition coil, often in the range of 20,000 to 45,000 volts, depending on the system. If you are measuring 116 volts going into the ignition coil, that voltage may not be sufficient to produce a spark. It's important to check the CDI box, ignition coil, and wiring for any faults or poor connections, as these can affect the overall performance of the ignition system. Additionally, ensure that the CDI is functioning correctly and is compatible with your ATV model.
