Re: Autolite vs Delco ignition coil

Steve:

I believe the two coils are equivalent, meaning electrically equivalent. The primary winding resistance of 1.5Ω would be typical, but likewise I do not know the turn ratio of either coil. I know of one difference, namely; The Delco coil does NOT have an integral hold-down bracket, while the AutoLite unit does. If you try to replace an AutoLite coil with a plain coil (typical of the Delco design or Pertronix), then a hold down bracket will need to be sourced. I've also noted that older coils tend to have the primary binding posts closer together, and not on the centerline, but that would not affect the interchangeability. Take a look at the parts book, specifically group 4.12032.
