I was riding my ds over the summer in sand and a little bit of water, I got done riding washed it off started it back up it started right up then I put it in the garage, then the next day I went out went to fire it up it started for about 5 seconds and stalled then lost spark, I replaced the CDI box with a big gun and the trigger coil and still no spark and the coils check out ok I checked out all the wiring and still nothing, I dont know what else to do its driving me nutts! PLEASE help me out! i'll appreciate it greatly!

 

well how is the primary side of the coil are you getting power to the coil atleast and im guessing coils work in a quad like they do in cars. the grounds are controlled and they should always be getting power to them so the winding collapses onto the secondary winding. im guessing its the same way. check for any corrosion on the connections and make sure its atleast getting to the coil and if it is and you said the coil was fine I would look at the plug and plug wire.

 

The coils checked out completely ok and the wiring cap but I dont get power to them, I dont know what else to check I cant understand why after replacing the parts I did that theres still no power going to them.

 

its the grounds from driving in dirt, water and other elements plus from constant starting try grouding out to an out side source do it with thick wire ...see if it works if not hit me back
