    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.

Zap!

OK I pulled the cable off plug 1 and held the rubber cable, not the end in my hand and started the bike. Got a nasty chock. Did it with No 2 as well. I am guessing this means I need new cables/coils since the cable as part of the coils?

Could this be the reason cylinder three isnt firing right?
 
yes u need new wires they are arcing
they say if u take a water bottle and mist it over wires u can see them arc if they are bad
 
Good one. I've done on Chevys and bikes.
New wires or new plug caps? These wires are usually alright .It is the plug caps that go bad.I get a slight feeling on the fourth plug but there is no problem with the wire or boot and the bike idles and runs fine.

Especially if you do it night or in the dark.

The other thing to remember is that by removing the plug wire you have open circuited the coil secondary which will result in voltages not normally seen in normal operation. This open circuit voltage wants to get back to the other side of the coil real bad, whether it be through you, or from jumping some extraordinary gap to the chassis. I've seen old Chevy coils jump from the secondary terminal to the primarys when cranked with the secondary coil lead pulled off which is about 1.5 inches.

Iv'e had bad caps cause miss fires due to both the wire termination and from the resistor pellet inside.

I like to use a grounded screw driver to check for arcing lug wires. just run it along the wires and watch for an arc and listen for a miss fire.
