Standard Ignition RY-1747 Accessory Power Relay

Accessory Power Relay for Ford Applications

The Standard Ignition RY-1747 is a direct-fit accessory power relay built to restore proper open and close operation in the electrical circuit. It uses a 12-volt design with a rectangular connector shape and 4 blade terminals for plug-in service on select Ford Focus and Ford Transit Connect models.

Built with durable electro-magnets and a high-temperature housing, this relay is made for the demands of underhood electrical service. The RY-1747 is a practical replacement when a relay no longer switches current cleanly across the contact points.

Key Features

• Accessory power relay for 12-volt systems
• Rectangular connector shape with male blade terminals
• 4-terminal, plug-in quick-connect design
• High-temperature housing for engine-bay conditions
• Direct-fit replacement for select Ford electrical applications
• Cross-reference part numbers include FEL-PRO 16219 and 1R3383

Detailed Description

Standard Ignition RY-1747 is engineered as a replacement accessory power relay for vehicles that require reliable switching of electrical current through relay contact points. It is compatible with 2012-2015 Ford Focus, 2010-2013 Ford Transit Connect, and 2010 Ford Focus applications listed with a rectangular shape, black finish, and 4 terminals. This part number, RY-1747, is also referenced in interchange listings for related service applications.

The relay’s plug-in terminal layout supports straightforward installation in the proper socket location, while the rugged housing and internal electro-magnet construction are selected to handle heat and vibration in automotive electrical systems. For buyers searching for a Ford Focus relay or Ford Transit Connect accessory power relay, RY-1747 provides a direct replacement path.

Common Problems This Relay Can Address

• Accessory power circuits that stop switching on or off correctly
• Intermittent electrical operation caused by relay contact wear
• No-power conditions in circuits controlled by the relay
• Heat-related relay failure in the engine compartment
• Electrical faults traced to a damaged or weak 12-volt relay

Installation Notes and Tips

Verify the connector shape, terminal count, and voltage before installation. This relay uses male blade terminals and a quick-connect plug-in style, so it should be matched to the original socket configuration. Confirm the vehicle application by year and model before replacing the relay in a Ford Focus or Ford Transit Connect.

For fitment, this part fits 2012-2015 Ford Focus, N/A; fits 2010-2013 Ford Transit Connect, N/A; and fits 2010 Ford Focus, N/A. The part number RY-1747 should be checked against the original relay and the vehicle’s electrical diagram when diagnosing the circuit.

Quality Assurance

Standard Ignition builds this relay with durable materials and a high-temperature housing to meet the demands of professional service work. The design follows a direct-fit replacement format intended to restore normal relay switching function in the specified Ford applications.
