* Under the hood, in the fuse box: This is the most common location. The fuse box is usually located on the driver's side fender well or near the battery. Look for a relay that's appropriately sized and might be labeled (though the labeling might be vague).
* On the starter solenoid itself: Less common, but some Caprices might have the relay integrated directly into the starter solenoid. In this case, you wouldn't have a separate relay.
To find it:
1. Consult your owner's manual: This is the best resource if you have it. The manual should have a diagram showing the location of all relays and fuses.
2. Look for a fuse box diagram: There's usually a diagram on the inside of the fuse box cover showing what each relay or fuse controls. Look for one associated with the starter motor.
3. Visually inspect the wiring: Trace the heavy-gauge wires leading from the battery to the starter. The relay will be somewhere along that circuit.
If you can't find it, a mechanic or a detailed online forum dedicated to 1986 Caprices could offer more specific guidance, perhaps with pictures based on your specific engine type. Providing the engine size (e.g., 5.0L, 5.7L) would help narrow down the search.
