Does a 1997 Dodge van 1500 have ballast resistor?

No, a 1997 Dodge Ram Van 1500 does not use a ballast resistor in its ignition system. Ballast resistors were primarily used in older vehicles with points-type ignition systems to reduce voltage to the ignition coil during cranking and extend its lifespan. By 1997, electronic ignition systems were standard, eliminating the need for a ballast resistor.
