grabatire..........ALL squarecan ignition coils need the "infamous ballast resistor"........NO ARGUE!!!!
They do NOT have a built-in resistor.
Surprizingly enuff, both the points (0.015") and the condenser work just fine on 12V. Same with the OEM 6V-starter motor. Works fine on 12V, positive or negative ground. .......Dell, a 12V advocate for the right reasons, who knows 8-ways to convert to 12V and they all work right the first time
