A friend is getting ready to fire up his engine for the first time since rebuild. He's got a Mallory electronic breakerless ignition module on stroked 383 SBC with MSD Blaster coil (we're fairly sure it is a 12v). The MSD instructions recommended using a ballast resistor if using anything other than a MSD unit to avoid damaging points. However, the Mallory unit has no points. Anyone set up a similar system. Are there any wiring diagrams around? We're in the UK and help and advice is a bit thin on the ground.
