Omron G8B-201-01 is a specialized automotive relay, primarily recognized as a Turn Signal / Flasher Relay for various Honda motorcycles
. Below is a detailed breakdown of its specifications, applications, and common troubleshooting steps. Product Overview
This relay is an Original Equipment Manufacturer (OEM) component designed to control the timing and operation of turn signal blinkers. It ensures that the indicators flash at a consistent, regulated speed, meeting safety and legal requirements for road use. Key Specifications Manufacturer:
Omron (a leading global manufacturer of electronic components). Part Number: G8B-201-01. Device Type: Flasher / Blinker Relay. Electrical Configuration:
Typically a 3-pin or multi-pin configuration (depending on the specific vehicle harness) designed for 12V DC systems. Compatible Models
This specific Omron unit was widely used across Honda’s lineup in the late 1990s and early 2000s. Known compatible models include: Honda Shadow series: Including the Shadow Spirit 750 and VLX 600. Honda CBR series: Specifically the CBR 600 F4. Honda NT 650 V Deauville: (1998–2001 models). Honda Sabre / Magna: Including the VF1100S Sabre. Honda VFR and Goldwing: Various sub-models from the same production era. Common Issues and Troubleshooting
Relays are mechanical-electrical hybrids and can wear out over time. Common symptoms of a failing G8B-201-01 include: Fast Flashing ("Hyper-flashing"): omron g8b-201-01
Often occurs if you have switched to LED bulbs without adding load resistors, as this relay is calibrated for the resistance of standard incandescent bulbs. Solid Light:
If the turn signal stays on without blinking, the internal switching mechanism of the relay may be stuck.
If neither side flashes and the fuses are intact, the relay has likely failed entirely. Purchasing and Replacement OEM vs. Aftermarket:
While you can find aftermarket "universal" 3-pin flasher relays, using the genuine Omron G8B-201-01 or the compatible G8B-211-01
ensures the correct pinout and fitment in the factory rubber mounting boot. Where to Buy:

This relay is a widely used part across numerous Honda models from the 1980s through the 2000s. Honda Nighthawk CB750 (e.g., 1991–2003). Honda Shadow series (VT600, VT750, VT1100). Honda CBR series (CBR600 F4). Honda NX650 Dominator. Honda VFR750. Honda Magna/Sabre (VF750, VF1100). 3. Cross-Reference and Replacements Omron G8B-201-01
is often interchangeable with parts from other manufacturers or updated Honda part numbers.
Honda OEM Part Numbers: 38301-MF8-771, 38301-MEG-000, 38301-MR7-004, 38301-KK9-952, 38301-MG9-681. Equivalent Models: Mitsuba FR-3303.
LED Compatibility: Standard G8B-201-01 relays are designed for incandescent bulbs. If switching to LEDs, a load-independent electronic flasher relay may be required to prevent "hyper-flashing". 4. Sourcing Information
As an older component, it is frequently sourced through specialized automotive and motorcycle parts retailers:
New/Replacement Units: Available from motorcycle-specific vendors like MotoShopItalia.
Used/OEM Surplus: Widely available on marketplaces such as eBay. Honda Omron Turn Signal Flasher Relay G8b-201-01 - eBay
Given the part number format and Omron’s typical naming conventions, this is a high-current PCB-mounted SPDT (Single Pole Double Throw) relay designed primarily for automotive and transportation applications (12V DC systems).
Key Identifier Breakdown:
- G8B: The series indicator for high-load, automotive-grade PCB relays.
- 201: Typically denotes the coil voltage and contact arrangement. In this case, it often refers to a 12V DC coil (standard automotive voltage).
- 01: Indicates the specific contact material, terminal plating, and sealing method (often flux protection or plastic sealed).
Frequently Asked Questions (FAQ)
1. Automotive Power Control
- Fuel Pumps: The fuel pump draws 5–10 amps continuously, but the inrush current can be higher. The G8B-201-01 provides a safety margin.
- Radiator Cooling Fans: These motors have high inductive spikes. The relay's contact material (often AgSnO2 or AgNi) resists welding or arcing.
- Headlight High/Low Beams: Directly switching headlights from a dashboard switch is dangerous. The G8B-201-01 acts as an intermediary, carrying the heavy current.
- ABS and Traction Control Modules: Used in secondary switching circuits within the main ECU (Electronic Control Unit).
Practical test checklist
- Measure coil resistance and confirm coil voltage rating before applying power.
- Verify contact continuity (NO, NC, COM) with a multimeter in both energized and de-energized states.
- Test switching under the intended load (or a safe surrogate) to confirm no excessive heating, contact welding, or erratic behavior.
- Observe mechanical operation (audible click, consistent motion) and check for contact bounce if timing matters.
- Run an endurance test under expected duty cycle if long-life is required.
6. Important Safety Precautions
- Do Not Exceed Ratings: Switching currents higher than 20A can weld the contacts together, causing the device to fail in the "ON" position, which is a fire hazard.
- Heat Dissipation: When switching high currents (near 20A), the relay generates heat. Ensure adequate spacing on the PCB and ventilation.
- Surge Protection: If switching inductive loads (motors, solenoids), use a snubber circuit or varistor across the load terminals to prevent contact arcing.
- Washing: This component is generally not washable. Do not immerse the relay in cleaning solvents after soldering unless the datasheet specifically confirms a "sealed/washable" version.
Typical applications
- Telecom and modem switching
- Signal routing in test equipment and instrumentation
- Low-current control lines in industrial control panels
- Isolation between microcontroller outputs and external signal paths
- Prototyping and small-scale automation where mechanical relay behavior is acceptable
