Give your starting circuit a fresh switch with the Standard Ignition Starter Relay SR-111. This relay lets a small signal from the ignition switch control the heavier current needed to engage the starter. It fits many vehicles, among them the 1977-1978 Dodge Charger, 1988-1990 Dodge Grand Caravan and 1977-1978 Chrysler Town & Country, as a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list and engine details.
A worn starter relay may show up as a single click with no crank when the key is turned to start, or as starting that works only some of the time. A weak battery, poor connections or a failing starter can cause the same symptoms, so test the circuit before replacing parts. If the relay is the fault, SR-111 replaces it.

Will this Dodge Charger starter relay fit my 1977 or 1978 Charger?
Yes. SR-111 is listed as a direct-fit replacement for the 1977-1978 Dodge Charger, and the "Vehicles it fits" section shows the engine details for each application.
What other vehicles does the SR-111 fit?
It fits many vehicles, including the 1988-1990 Dodge Grand Caravan and the 1977-1978 Chrysler Town & Country. The "Vehicles it fits" section has the full list.
What does a starter relay do?
It lets the low-current signal from the ignition switch control the higher current that engages the starter, so the switch itself does not carry that load.
What are signs a starter relay may need replacing?
Signs include a click with no crank, no response when you turn the key, or starting that works only some of the time. A weak battery, bad connections or a failing starter can cause the same symptoms, so diagnose first.
How is the SR-111 installed?
Disconnect the battery, remove the old relay and install SR-111 in its place. Follow the vehicle service information for the correct procedure on your application.
