The Dodge starter relay is usually located in the engine bay’s power distribution center (the main fuse/relay box) near the battery. In many newer Dodges, the starter control is integrated into the IPM (Integrated Power Module), so there may not be a separate, user-serviceable starter relay.
The exact location can vary by model and year, so this guide outlines common places to check, how to identify the correct relay, and what to do if the relay isn’t the problem.
Common locations to check
Before inspecting, note that some models place the starter control in a dedicated relay box, while others rely on the IPM to manage the signal. Here are the most frequent possibilities you’ll encounter.
- Engine bay power distribution center (PDC) or fuse box near the battery; look for a relay labeled “START,” “S,” or “STARTER.”
- Under-hood fuse/relay box mounted near the engine bay, sometimes with a separate “Starter” or “ST” relay in the box.
- Integrated Power Module (IPM) in newer Dodges; the starter signal is routed through the IPM, so there may be no separate relay to replace.
- Older Dodge models sometimes used the starter solenoid itself as the switching device, with no distinct relay in the fuse box—replacements involve the solenoid and wiring rather than a separate relay.
To confirm the exact arrangement for your vehicle, check the diagram on the PDC/relay box lid or consult the owner's manual or a service manual for your year and model.
How to verify and test the starter circuit
Once you know where the relay should be, follow these steps to determine if the relay, wiring, or starter is at fault.
- Check fuses: Inspect the fuse labeled for the starter circuit in the PDC or IPM area and replace if blown.
- Listen for a click: When turning the key or pressing the start button, a clicking sound from the relay area typically indicates the relay is energizing; no click may indicate a faulty coil or wiring issue.
- Swap with a known-good relay: If you have another identical relay in the same box, swap it to see if the starting function follows the relay.
- Test the relay coil and contacts: With the ignition on, measure the coil resistance (per service manual) and verify there is continuity between the appropriate terminals when the relay is energized.
- Inspect wiring to the starter: Look for damaged or corroded connections at the battery, starter solenoid, and ground strap; clean and tighten as needed.
- Consider the IPM/PCM role: If relays test OK but symptoms persist (no crank despite power to the solenoid), the issue may lie with the IPM/PCM or associated wiring rather than the relay itself.
If you’re not comfortable performing electrical tests, or the problem persists after basic checks, seek a qualified technician for diagnosis and replacement.
Model-specific notes
Charger and Challenger (recent generations)
In many modern Chargers and Challengers, the starter control is routed through the engine bay IPM or the main fuse/relay box; a dedicated, user-serviceable starter relay may not be present in all trims. Always consult the diagram on the PDC lid for labeling.
Durango and Ram pickups
Durango and Ram trucks commonly use an IPM-based control for starting; some years offer a separate starter relay in the engine bay box, while others rely on the IPM. Diagrams and labels on the engine bay box will guide you to the correct component.
Older Dodge models (1990s–2000s)
Older Dodges often placed the starter relay in a fuse box in the engine compartment or used the starter solenoid as the switching device without a separate relay. If you’re working on a vintage model, refer to a period-specific service manual for the exact layout.
Summary
Locating the Dodge starter relay depends on the model and year. In most cases, you’ll find it in the engine bay’s power distribution center near the battery, or the function may be handled by the Integrated Power Module in newer vehicles, with no separate relay to replace. Always verify with the vehicle’s diagrams and manual for your exact year/model, and consider professional help for testing or replacement if the issue persists.
Where is the starter solenoid on a Dodge Ram?
For modern vehicles, the starter solenoid is attached to the starter motor itself. You'll often find it mounted under the vehicle at the bell housing – where the engine and transmission are joined. Identify it by the thick battery cable that's fastened to it along with a thinner switch wire.
Where is the main starter relay located?
Starting relay position
It might be in the power box (also called the fuse box), under the dash panel, or near the right fender. In most cars, you'll find it under the hood in a big box with a black cover. This is where all the car fuses and relays are kept. People call this the fuse box too.
How to jump start a starter relay?
Position. If you don't your car may immobilize and you'll be unable to turn it on at all. And that's how you do it guys.
How to tell if a starter or starter relay is bad?
- Engine Fails to Crank. One of the most obvious signs of a faulty starter relay is the engine failing to crank when the ignition key is turned.
- Intermittent Starting Issues. A failing starter relay may cause inconsistent starting behavior.
- Clicking Noise When Starting.
- Starter Motor Stays on after Engine Starts.
