Voltage Regulator and/or Ballast fails

Hi, Big Block cars used the same engine harness as a 6 cyl car. Just a thought, do some research on the Ohm rating of your ballast resistor. If converted to electronic ignition the ohm rating of the ballast could be mismatched when using the original ballast from the points system. Ballasts are available with different ratings. This could cause the ballast to over heat and go faulty prematurely. I cant comment on the alternator wiring or set up without seeing it. Worth a look IMO. Other thoughts are sure to come for other members.
