1992 yamaha fzr600r coil has power but no spark at plugs

SOURCE: no spark

remove the ignition coil from the bike.

The primary winding should have a resistance between 2 and 6 ohms
The secondary winding should have a resistance between 19Kohm and 40Kohm.

In fact the primary must have less than a 50ohm, but there MUST be a resistance.
The secondary should have a resistance of 15.000Ohms and more, but there MUST be a continuity.

SOURCE: cant get a spark from yamaha kodiak 400

I did one about a year ago & it was the pulser coil(black plastic pickup next to magneto behind L/H engine cover) but

1. I'm not suggesting that this is definatly the fault
2. But id check it first
3. I havent got the spec for it but got it from my Yamaha dealer easy enough(you'll need the wire colours as well)
4. contact me back if you can't get them and i'll see what I can do(it'll be another week before I can get it as my phone is shot! blew the line clean out of the wall in a storm a couple of weeks ago)

SOURCE: I am not geting a spark on my yamaha cygnus, there

check to see if the magnito has come loose, although you would hear it if it was, maybe the points need replacing

SOURCE: No current to spark plug

Best thing to do is get the whole system checked out by a yam electrician ,It will be less cost to you in the long run .as they can test each component for faults .

If you've tested the ignition components and everything is good to go, the most likely candidate for causing intermitent fire is actually the spark plug cap.

First, just pull the cap off the plug and take a look inside to make sure the fitting is still clamping snuggly and squarely down on the plug. Now, holding the plug wire still, rotate the boot a full turn clockwise. Replace the boot and try it out. If this hasn't eliminated the issue, the little wires within the plug wire may be frayed and broken. To check this, pull the boot back off of the plug. Again, holding the plug wire still, rotate the boot COUNTERclockwise and unscrew it right off the end of the wire. Take a look in the end of the wire and check the condition of the little wires that should be in the center of the plug wire. If the don't look 100%, use some wirecutters and snip off about 1/4" of the plug wire. Replace the plug boot by insuring the screw tip of the boot enters exactly in the center. Give it a few turns clockwise-until it snugs up. Replace the boot onto the plug and you should be ready to go! I hope this helps! Good luck!
