I'm not sure if we're allowed to post links but if we are, try following this...
https://www.buggydepot.com/tech-cent...uide-no-spark/ it has the voltages needed at test points on the ignition system, multimeter set on AC
- There should be between 20vAC ~ 100vAC coming from the CDI power wire (Black/Red), although much lower voltages will still be able to produce spark.
- There should be at least 0.05vAC coming from the trigger wire (Blue/Yellow).
- CDI output at least 18 Volts AC
- if the link posted I'm just repeating what they had...
