12V Conversion coil question for John T or others

Posted by Ron in Nebr on March 31, 2007 at 19:45:41 from (66.252.113.135):

Ok, got your post about checking to see what's printed on the coil and that a coil rated at 12v "without ballast" does not need a resistor.

Question- all the points-type car engines I've ever worked on had a ballast, either a separate one or in the wire itself. Do all these, mostly 12v systems, actually have a 6v coil thus requiring the resistor? I'd always been under the impression that the resistor was required to reduce voltage to the points to keep 'em lasting longer.....and when we'd convert a GM points system from points to HEI, we'd run a new wire that bypassed the original wire that had a resistor in it. So, does a normal 12v system need a resistor with a 12v coil or not???
