Where is the Ignition Coil Resistor locaed on a 78 ford E150?
A 1978 Ford E-150 doesn't have a separate ignition coil resistor. The resistance needed to limit current to the coil is built *into* the ignition system itself, likely within the ignition module or the ballast resistor which is often integrated into the coil assembly or a nearby component. There isn't a standalone resistor like in some older vehicles.
