Hi Stew, just to tell you our set up over here, this is what all my carriers use: original 6V generator housing, that has the fields changed with 12volt ones from a Lucas C45 12volt gen. So this now produces 12volts. We do not run through the old ford resistor in the dash anymore. Fit 2 x 12volt to 6 volt resistors for the 2 electric gauges, available from Mac's Auto. Use a 12volt coil that requires an external resistor with it. Run a wire direct from the starter solenoid terminal that gets power when you push the start button, direct to the coil, also fit a one-way diode in this line ,( get the diode around the right way ! ), so no current can back feed from the coil to the starter solenoid. Run your normal coil wire through to the bottom terminal of the external resistor and then out of the top terminal to the coil terminal that is also where the one from the starter feed in. Run neg earth. All dizzy , cap, points, etc original. Points set to about .014 I think. Make sure you run new copper leads. Also we make a point of using an original condenser. So......this set up gives you 12volts to the dizzy on start up and as soon as you release the start button you are running about 9.5volts through the coil, so it does not heat up.This gives you big blue sparks and works every time. Remember do not file points, as this takes the contact surface off them, clean with a rag to take any furry stuff off. Coil is situated on the top L/H corner of the head off a bracket that bolts to the intake manifold bolt holes.( This is why new points always work best, because guys have not stuffed with them ) Makes sense to you ?
