HUH?
ignition is supplied by twelve volts going from one side of the coil, through the primary windings of the coil, out of the coil and through the pigtail to the points, condensor and grounding in the distributor body. When the points open the "field"(primary winding coil inside the coil) collapses and triggers the secondary coil, which fires through the secondary terminal of the coil, out the distributor wire, into the center terminal of the distributor cap, onto the rotor where it is directed to whichever button on the cap it is pointed at and out through the plug wire to the plug.
No way a coil sends electricity back through the points. Common for early British coils to open circuit, especially when they warmed up. What was burning your points up was failure or incorrect resistance of the condensor(oh, what fun it was to measure fareds)
I will put my two cents in whenever I can, not trying to attack anyone, so please do NOT take it as such.
Trying to inform people of the way things work(or in LBC's case, supposed to work) so that the future generations are not "trained" improperly. People learning ignition systems today do NOT learn about point setups, so if they hear improper stuff as "the bible" they may believe it.
