:
The suffix “-DC12” explicitly states the coil voltage. Often, the base part number G8B-201-01 implies DC12, but check the datasheet. Omron uses various suffixes for plating and sealing options.
: Apply 12V positive and negative power directly to the coil pins. You should hear a sharp, metallic click. While the power is active, check the load pins again with your multimeter; the resistance should drop immediately to less than 0.5 Ohms. Sourcing Replacements and Modern Substitutes
When you activate your turn signals, the relay uses an internal electronic circuit to pulse power, causing the lights to flash on and off. This model is known as an . It's specifically designed for traditional incandescent bulbs, not LED lights.
Because the G8B-201-01 is a legacy automotive part, buying it requires navigating a few specific options depending on your preference for OEM authenticity. Finding Original Units omron g8b-201-01
Secure the replacement relay back into the chassis rubber holder to isolate it from road vibrations, reconnect the battery, and test the left and right blinkers.
The is more than just a switch; it is a robust, engineered solution for high-reliability automotive and industrial applications. Its ability to handle 20 amps continuously, survive extreme temperatures from -40°C to +85°C, and resist vibration makes it a cornerstone component in engine control units, body control modules, and aftermarket power systems.

: You must place a flyback diode (e.g., 1N4007 or 1N4148) in reverse parallel across the coil. When the relay turns off, the coil generates a high negative voltage spike that can destroy driving transistors. Cathode (stripe) to +12V, anode to ground. : The suffix “-DC12” explicitly states the coil
: If you replace your original bulbs with LEDs, the standard G8B-201-01 may cause "hyperflash" (rapid blinking) because the lower resistance of LEDs tricks the relay into thinking a bulb is out. : Upgrade to a Plug-and-Play LED Flasher Relay
Automotive relays must withstand harsh conditions under the hood or frame. The Omron G8B-201-01 is built around a standard optimized for Japanese motorcycle architectures.

: Feeds clean, un-attenuated battery power directly to the CDI (Capacitive Discharge Ignition) or Spark Unit when the key is turned to the "ON" position. Common Symptoms of a Failing Relay
This indicates burned or pitted load contacts. The armature moves, but the contact surfaces are covered in non-conductive carbon. Replace the relay. : Apply 12V positive and negative power directly
is a classic automotive turn signal flasher relay primarily manufactured by Omron as an original equipment manufacturer (OEM) part for Honda motorcycles. Known interchangeably by its Honda factory part number, , this component has regulated indicator flash rates across generations of iconic bikes, including the Honda Nighthawk CB750, VF1100S Sabre, and the Shadow series.
If you have a known-working relay of the same type, swap it in. If the problem goes away, you've identified your faulty unit. You can also test the relay's connector with a multimeter to ensure it's getting power and a good ground.
As an Omron component , it offers superior mechanical and electrical endurance compared to generic aftermarket alternatives.
