1. RE: Ballast resistor question (score: 1): Author: "Stephen Hanselman" <tr6@kc4sw.com>; Date: Tue, 1 Jul 2003 07:59:49 -0700; The spark coil works by the effects of a collapsing magnetic field. All transformers operate by changing magnetic fields. The basic theory is that a magnetic field crossing a wire will induce a volt; /html/6pack/2003-07/msg00008.html (9,702 bytes)
2. RE: Ballast resistor question (score: 1): Author: "Stephen Hanselman" <tr6@kc4sw.com>; Date: Tue, 1 Jul 2003 07:59:49 -0700; I have seen a number of comments here that indicate that the ballast resistor reduces the current. This is not the case. in any given series circuit, and anything that is across a battery is in gener; /html/6pack/2003-07/msg00009.html (9,628 bytes)
3. Re: Ballast resistor question (score: 1): Author: "Mark Anderton" <andertonm@cox.net>; Date: Tue, 1 Jul 2003 18:45:49 -0400; Ohm's law says I=E/R, so if I add a resistance in series (the ballast), the current flow is reduced. Granted, current flow is the same through all components in the series circuit, but as I add resis; /html/6pack/2003-07/msg00020.html (10,951 bytes)
4. Re: Ballast resistor question (score: 1): Author: "Gary Fluke" <res0s0t7@verizon.net>; Date: Tue, 1 Jul 2003 20:40:35 -0700; Yep, otherwise every circuit would be a short circuit...

5. RE: Ballast resistor question (score: 1): Author: "Stephen Hanselman" <tr6@kc4sw.com>; Date: Wed, 2 Jul 2003 07:51:10 -0700; OK you caught me:) But, the issue is not really the amount of current flow through the ballast resistor and coil but the voltage across the coil. Assume that the ballast resistor causes a drop of vo; /html/6pack/2003-07/msg00097.html (7,115 bytes)
6. Ballast resistor question (score: 1): Author: "TR6 Triumph" <tr6_1969@hotmail.com>; Date: Mon, 30 Jun 2003 19:54:39 +0000; Hi list! The posting speaking about the bad points possibly caused by lack of a ballast resistor forces me to ask the questions: what is a ballast resistor and what exactly does it do in the ignition; /html/6pack/2003-06/msg00611.html (7,803 bytes)
7. Re: Ballast resistor question (score: 1): Author: "Mark Anderton" <andertonm@cox.net>; Date: Mon, 30 Jun 2003 18:50:43 -0400; The ballast resistor reduces the amount of current flowing through the points and coil. Advantages include less pitting of the points and cooler coil operation. If you check the voltage drop across t; /html/6pack/2003-06/msg00616.html (9,189 bytes)
8. Re: Ballast resistor question (score: 1): Author: tr6taylor@webtv.net (Sally or Dick Taylor); Date: Mon, 30 Jun 2003 15:55:41 -0700 (PDT); Dave--You can check to see if the ignition wire is ballast resisted by measuring the voltage going thru the wire to the coil + terminal. If it's less than 12V, it's probably going thru a ballast. Som; /html/6pack/2003-06/msg00617.html (8,024 bytes)
9. RE: Ballast resistor question (score: 1): Author: "Jim Swarthout" <jswarth1@tampabay.rr.com>; Date: Mon, 30 Jun 2003 19:18:06 -0400; I had always assumed that the ,(capacitor), condenser prevented a current overload at the points? Current causing the pitting of the points? Occasionally I'm wrong! Anyone care to describe how an ig; /html/6pack/2003-06/msg00619.html (7,631 bytes)
10. RE: Ballast resistor question (score: 1): Author: "Navarrette, Vance" <vance.navarrette@intel.com>; Date: Mon, 30 Jun 2003 16:39:28 -0700; You have it correct. The coil is an inductor, which means that energy is stored in the magnetic field surrounding the core. When the points open, the magnetic field collapses, and this stored energy; /html/6pack/2003-06/msg00620.html (10,041 bytes)
11. RE: Ballast resistor question (score: 1): Author: "Jim Swarthout" <jswarth1@tampabay.rr.com>; Date: Mon, 30 Jun 2003 20:20:07 -0400; Fantastic explanation! I would like to add a bit more...kind of on the mechanical side for all to get a visual. An ignition coil actually consists of two different coils of copper wire. The primary; /html/6pack/2003-06/msg00622.html (11,210 bytes)
12. Re: Ballast resistor question (score: 1): Author: "Mark Anderton" <andertonm@cox.net>; Date: Mon, 30 Jun 2003 20:35:01 -0400; I think the condensor (capacitor) actually provides the path through which the current flows when the coil magnetic field is collapsing. If I recall, you take it out and the car doesn't run. Mark And; /html/6pack/2003-06/msg00623.html (11,082 bytes)
13. RE: Ballast resistor question (score: 1): Author: "Navarrette, Vance" <vance.navarrette@intel.com>; Date: Mon, 30 Jun 2003 13:54:48 -0700; The ballast resistor is a component (in the case of the TR6, a special length of high resistance wire embedded in the wiring harness) that drops the voltage applied to the ignition coil to around 6v; /html/6pack/2003-06/msg00624.html (9,769 bytes)
14. RE: Ballast resistor question (score: 1): Author: "Hugh Fader" <hfader@usa.net>; Date: Mon, 30 Jun 2003 21:29:40 -0400; A minor correction if I may. A regular transformer has two separate windings. An ignition coil is a special kind of transformer called an autotransformer. That means the primary and secondary winding; /html/6pack/2003-06/msg00626.html (8,026 bytes)

Re: Ballast resistor question (score: 1): Author: "Gary Fluke" <res0s0t7@verizon.net>; Date: Mon, 30 Jun 2003 18:42:09 -0700; This site has a fairly involved explanation of the effects of a condenser in an ignition circuit. The part about the oscillation is interesting. I, for one, never thought about that before: http://w; /html/6pack/2003-06/msg00627.html (12,359 bytes)
16. Re: Ballast resistor question (score: 1): Author: Don Malling <dmallin@attglobal.net>; Date: Mon, 30 Jun 2003 21:44:43 -0400; I had always thought the capacitor was charged as the points opened, thus prevented arcing across at the points when they opened. Arcing transfers point metal from one side to the other. Pit on one s; /html/6pack/2003-06/msg00628.html (8,026 bytes)
