MSD Ignition - No Start

I agree about having a weak battery . We have smoked 3 MSD 6A's in the last 5 years because of weak battery , bad ground , low voltage . MSD's are very voltage sensitive . We switched to Petronix Ignitor II , got rid of the ballast , used their coil and no more issues . Vacuum advance for the street .

YOU USED A BALLAST W/ AN MSD, WHEN U DONT HAVE TO ?/
I`ve had 4 msd 6`s on 4 diff cars and not one failure or ballast resister------------no brag, just fact.

Anyone run a double strike petronics w/ an aftermarket fuel inj system ??----------
they sound good if a person is buying a new one . -------jmo
