The MGR-C20 and MGR-C20S relays are replacements for the Siemens V23073 and other relays on your late model Guzzi or Ducati and the Hella 4RD 931 524-02 in your Big Dog or Cub Cadet These relays are 4.6 mm. taller and 3.7 mm. longer than the V23073.  They meet the ISO Micro plug in relay standard and fit fine in my ’04 Café Sport.  Inductive spike suppression resistors are included across the coil terminals to protect other devices in the circuitry as well as the relay’s contacts.  This resistor is not present in the V23073.

The MGR-C20S is the epoxy sealed version of the MGR-C20.  The dimensions and ratings are the same.

Prices are $6.00 each for the standard and $8.50 for the sealed version, plus $8.00 for shipping and handling in the domestic U.S. via priority mail.  Shipping costs to other destinations depend on method and distance.  Payment can be made by check or money order (either postal or Western Union) payable to:
