YT3600 no spark!

[valdez]

Doe anyone have a suggestion for a No-Spark condition?    I replaced the ignition switch with a unit bought from Yam Genuine Parts in Canada.   The engine cranks fine, lights, deck pto relay, fuel pump all work, but the engine has no spark.   Tried different plugs, check every wiring connection I can find....    This tractor ran very well as it is in mint condition...   Any help would be greatly appreciated!   Thanks in advance!

Hello , here is a few other items to check.
1-Your battery must be fully charged 12 volts....a lot of people do not realize this.If your battery is less than 10volts the CDI will not genrate a spark, it will still turn over,but not spark.
2- There is a seat switch that shuts of the tractor if you get off it while its running. Alot of people disconnect it.

Hope this helps.
