Here's why you're unlikely to find a traditional ballast resistor:
* Electronic Ignition: 1992 vans likely used electronic ignition systems. These systems control the ignition coil's voltage electronically, eliminating the need for a separate ballast resistor to reduce voltage to the coil. The ignition module (or control unit) manages the coil voltage directly.
* Integrated into the Coil: In some cases, the voltage regulation might be built directly into the ignition coil itself.
If you are troubleshooting a problem and suspect a ballast resistor issue:
1. Consult your van's repair manual: This is the most reliable source of information for your specific vehicle's electrical system. The manual should show a wiring diagram and identify components.
2. Check the wiring diagram: Look for a component labeled "ballast resistor" or something similar. The diagram will show its location.
3. If you can't find it: Your van likely doesn't use a separate ballast resistor. The problem may lie elsewhere in the ignition system (e.g., ignition coil, ignition module, crankshaft position sensor, etc.). You'll need to consult a wiring diagram and/or a qualified mechanic.
In short, without knowing the make and model of your 1992 van, it's impossible to pinpoint the ballast resistor's location. It's highly probable that it isn't present in the traditional sense.
