Therefore, there's no single location to check. If your van has one, it's most likely:
* Near the ignition coil: This is the most common location for an ignition resistor. Look closely around the coil for a small, possibly heat-sinked, resistor.
* In the wiring harness: It might be integrated into the wiring harness itself and not a separate component. This would make it difficult to identify visually.
If you're trying to troubleshoot an ignition problem, it's much more likely the problem lies elsewhere than a failed ignition resistor in a modern vehicle. Consider checking the ignition coil, distributor (if applicable), ignition switch, crankshaft position sensor, and other components of the ignition system before focusing on a resistor that may not even exist.
To accurately determine whether your Dodge van even has an ignition resistor, you'll need to consult a repair manual specific to your van's year, make, and model. The manual will have a wiring diagram that shows the ignition system components.
