[30 Closed Cab PU]

Interesting about the full voltage statement. When I checked my 6 v positive ground system using the pencil flair test it was correct. Bought a spark tester that has the movable wire in it that is put in series with the dist./coil lead so you can see where the spark starts degrading. Noted this, and then switched primary connections on the coil, and did see about a 40 percent degrease in the reading. Switched the leads on the coil back to correct and got the same reading as teh 1st correct hookup reading, so did not see a decrease. Perhaps you have to run it incorrectly for a while to get the core magnetism issue.


Not familiar with ignition coil constructions - they have a conductive core the windings are wrapped around? Might be a silly question, but would like to know.
