    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.

Steve, The secondary ignition system is basically a spark transmitter with an antenna attached. It is also a resonant circuit (tuned circuit) because of the inductance of the wires inductance and the distributed capacitance of the coil (two wires in parallel is a capacitor). By adding a resistor to an L (inductance) C (capacitance) circuit you reduce the intensity of the oscillation and lower the frequency the circuit resonates.

In layman's term's, you reduce the intensity and move the harmful interference so it won't cause any objectionable operation to other devices.

Thanks Dale,
OK I'm done with it, I get the gist (I think). In other words those resistors are unnecessary. I thought impedance was going to come up somewhere in the equation.
 
Steve, Next time be nice to me. I'm not an electrical engineer. :eek:
 
Issue fixed. The capacitors were apparently bad. Had a buddy who's a guitar tech and therefore a pretty good electrical engineer take a look at it. First thing he said the caps were leaking.

So new caps, new points, and she fires right up, first kick.
