Timing changed after Cap + rotor swap?!

Quality or mold differences for the cap maybe?
and or rotor.
Re-install the old cap see if it comes back.

this
might even be able to get a 4th reading by installing the old rotor with the new cap


or...you may be able to loosen the snaps on the cap and clock it back to where it was

(als ik me niet vergis zit er altijd een klein beetje speling in, en als je maar 12 graden nodig hebt, zou het kunnen dat de oude distributie kap helemaal naar links zat, en de nieuwe helemaal naar rechts...of andersom)

as for your friends idea that each wire is one post of, thats a rather unsubstantiated claim (nice way of saying dumb)
assuming your working on a V8, that would put you off 45 degrees (60 if your working on a 6 banger) and i doubt it would run

which brings up the next question...what are you working on?
