Title: NO SPark
Post by: Jsquared on July 30, 2013, 11:50:11 PM

Help I have no spark changed ignition coil cdi box grounds are good checked reckecked and replaced!! I used a light tester just to see if i was getting power to ignition coil i am but still no spark so I decided to ground out one end of the light tester and stick the other end in the sparkplug wire hole it flickers when I turn the bike over so I am guessing it is getting power but why no spark? it is my understanding the cdi box tells the ignition coil when to send spark so maybe I have two badd cdi boxes?

I am assuming you made sure the wire going to the plug is ok as well.  I know you said you stuck your tester and it was flickering, but it may still have a break or something internal.  So could provide power to light a tester but not enough to fire a plug.  Have you changed plugs just to make sure the plug is not bad?

Just a thought.
