Secondary Ignition
for your 1993 International 3900FC


Your International 3900FC ignition system includes two circuits that work together to deliver the spark to the spark plug. The secondary ignition connects the spark plug and ignition coil, while the primary circuit connects the coil and battery. Malfunctions in either circuit can cause problems starting your vehicle, so consider replacement parts from StockWiseAuto.com.


In today's vehicles, you have a choice of either an electronic or distributor-free ignition system. Use caution when testing the secondary circuit; it carries a high-voltage current. When you've determined that your International 3900FC needs a new secondary ignition, come to StockWiseAuto.com for the lowest prices in OEM parts.
