    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Faulty Ignition Coil?

it looks like there is no spark on my no. 1 cylinder. No. 3 is working well. It is possible that the ignition coil is not good? I'll exchange the plug wire and see if is OK.
 
Would this be on a motorcycle? A Suzuki motorcycle? Possibly a GS motorcycle?
Model, year, displacement, things like that probably help.
If you put them in your signature, it would help everyone, including yourself.
 
If it has three cylinders, it may have four. If it's a four cylinder Suzuki the #1 and #4 share a common coil, if four works one probably does too.
Fix the plug caps.
 
Hi,

How did you test? Check my little website for how to change plug caps and perform ignition/electrical troubleshooting. Keep us informed.

Thank you for your indulgence,

I haven't seen Cliff's testing of the coils, wires and ignition, but he always has good information, so I would start there. And thanks for the info.
 
With tank off, unplug ignition coils (disconnect spade connectors)- with a decent multinmeter measure ohm resistance across the the spade connectors on the coil- should be about 4 ohm. Now remove plug caps from plug wires; then measure resisitance between these two wires- should measure about 12 kohm.
