Re: Thinking of going from MSD to HEi
About 5 years ago, MSD bought Mallory. Two and a half years ago, Holley bought MSD. MOST issues with MSD box failures were/are from very bad, defective MSD Blaster coils. Good ones were made to early 2004, then, Mexico (at one time, 70 percent defective), and now, China. A defective MSD Blaster coil that is slowly "layer shorting" to failure, can kill an HEI, or MSD module flat out in as little as 30 seconds, for what people say is "no apparent reason".
NOTHING ever fails "for no apparent reason".
Does the bad quality control also include the coil in cap versions ? This is my third MSD digital 6 plus box in approx. 10 years, and I think I have only changed the coil in cap once. Maybe, I should change the coil in cap. The one I have in there is made in Mexico.... .
