What do you have now, an alternator with an EXTERNAL regulator, or a 12 Volt GENERATOR? What "converter" did you replace? I would recommend a Delco 10 SI or 12 SI alternator with the standard, original 3- wire hookup. A good diagram to do this is on the "My Old Fords" site linked below. Wheter you have a 9N, a 2N, an early 8N, or a late 8N, there's a diagram there that will work for you. This conversion is cheap and easy to do, uses a standard, off-the-shelf alternator with standard internal parts (rather than the various varieties of aftermarket internal parts a "one-wire" alternator may be equipped with). Using a standard 3- wire alternator will guarantee it beginning to charge at low engine speeds (which not all 1- wire alternators are good at), and will cause less confusion and expense, down the road, if alternator repairs are ever needed. The "marker light" specified in the conversion information acts as the charge indicator "idiot light" AND limits current "backfeed" into the ignition circuit from the alternator's #1 terminal. This prevents the engine from continuing to run when the ignition switch is shut "off", and prevents possible internal alternator damge. Alternately, a 3- Amp, 1000 PIV diode works in the place of the lamp, if a lamp is not desired. For pros and cons of 1- wire and 3-wire alternators, see also THIS site: Link
