Detailed Description

Standard Ignition SR-109 is a starter relay for electrical, charging, and starting system repair on select Chrysler Imperial, New Yorker, Newport, Town & Country, 300, and Dodge Monaco models.

Installation Notes and Tips

  • Verify the vehicle uses a 12-volt starter relay with a rectangular connector and 3-terminal layout before installation.
  • Match the terminal style to the existing stud and blade configuration on the vehicle harness.
  • Inspect the relay connector, terminals, and surrounding wiring for heat damage or corrosion before replacing the relay.
