Computer Control Relay for Nissan and Isuzu

Standard Ignition RY-39 is a 12-volt computer control relay built for electrical system service on a wide range of Nissan and Isuzu applications. With a 30 amp amperage rating, 4 blade terminals, and a rectangular connector shape, it matches common OE-style relay layouts used in engine and body control circuits.

Key Features

  • 12 V computer control relay for automotive electrical repair
  • 30 A amperage rating for standard relay circuit loads
  • Rectangular connector shape with 4 male blade terminals
  • Non-continuous duty relay construction
  • Direct replacement style for many Nissan and Isuzu applications
  • Standard Ignition RY-39 part number for catalog matching

Detailed Description

Standard Ignition RY-39 is a computer control relay used in vehicle electrical and lighting systems where a switched 12-volt signal is needed to control a circuit. The relay uses a 4-terminal blade design with male terminals and a rectangular housing interface, making it a practical replacement for OE-style relay locations found across Nissan 200SX, 240SX, Maxima, Pathfinder, Sentra, Altima, and related Isuzu models. This part cross-references Gates 19936 for the same application.

Compatible With 1977-1997 Nissan 200SX, 240SX, Altima, Maxima, Pathfinder, Pickup, Quest, Sentra, 300ZX, Pulsar NX, NX, 720, 210, 310, 510, 810, and 280ZX applications, plus select 1981-1991 Isuzu I-Mark, Pickup, Trooper, Amigo, Impulse, and Rodeo applications listed in the fitment data. Standard Ignition RY-39 is a focused electrical replacement for relay circuits that require a 4-blade, 12-volt, 30 amp configuration.

What It Helps Solve

  • Intermittent relay operation in engine or body control circuits
  • No-start or accessory power issues caused by a failed relay
  • Electrical switching faults in 12-volt relay-controlled systems
  • Relay replacement needs on Nissan and Isuzu OE-style applications
  • Connector mismatch concerns when replacing a 4-terminal blade relay

Installation Notes and Tips

Verify the relay footprint, terminal count, and connector shape against the original unit before installation. Confirm the vehicle uses a 4-terminal blade relay and compare the OE number or service part reference when available. Standard Ignition RY-39 is not a continuous-duty relay, so it should be used in circuits that match its duty cycle and amperage rating.

Quality Assurance

Standard Ignition supplies electrical components for service replacement use, and this relay is built to match common OE-style specifications for voltage, terminal layout, and circuit rating. Review the vehicle fitment notes carefully for OE number references and connector details before ordering.
