Computers hate electrical interference...so KEEP any capacitors you have. The one in the old dizzy was the same device but did a slightly different job from the ones on the coil, alternator and regulator. I am putting a modified dizzy in my Lima 2.3 in a sportscar with points...YES, points. Below 5000 RPM points work great on a 4-banger with hotter coil and copper plug wires...but DO NOT use copper wires on a computer engine! This is NOT to start an argument, but points by design make a longer spark than computer ignitions. That is why MSD was invented. Multiple Spark Discharge (MSD) is to simulate the longer points spark and give a better chance to ignite the fuel/air mix. Today's computers time FI input, spark timing, variable-valve timing, listen for knock, monitor O2 exhaust, MAS, MAP, and much more. Points mechanical system can't possibly do that. I am doing this in an old-school 67 Alpine with a modified 85 2.3 from a carb. Mustang...just to eliminate any computers. The A4LD overdrive will lock-up the converter with a button on the shifter...which was done by the computer originally. Just a FYI note.
