? coil, pertronix

I have a internal resistor coil which reads about 3 ohms between the + and - terminals, this I believe is normal. However, when I read between the coil output and either the + or - terminal, I get a reading of about 13.5K ohms. Is this normal? If not, what kind of a reading should I get? Also, is there any way to check a Pertronix electronic ingnition with an ohm meter? Any help would be appreciated.

I moved this to the "Ignition System" forum.
Internal resistor coils should be about 3 ohms between the +'ve and -'ve terminals. I don't know what the appropriate resistance should be between the secondary output (the coil tower) and the primary terminals. Intuitively, I would think it should be darn high, if not infinite, since there really isn't an electrical connection between the primary and secondary sides of a coil (uses a primary magnetic field that collapses to create the secondary voltage). Anyone else know, or have a coil that they could test?
As for checking a Pertronix with an ohm meter, I am not aware of any specific test. It uses a "Hall Effect" transducer to trigger an internal switch, so it either works, or it doesn't.

Keith is right on the checks and also the lack of a way to really check out the pertronics. By the way welcome back Keith hope the vacation was fun.
