Sidestand relay

42H-85740-00-00 | - | - | 1987-1988 | - | 1986-1991 |
This relay was used as a protection for sidestand security switch at the begining of Virago production. If bike's sidestand is down, for security reasons the bike cannot start. Later this relay was abandoned as unnecessary while sidestand switch remained (is connected directly to TCI).
Fuel pump relay

Fuel pump relay is used for turning the fuel pump on/off. In 1991/1992. old relay 4U8-02 model was replaced with newer one 25G-01.
Diode assy

4H7-81980-M0-00 | - | 1992-1998 | 1989-2001 | 1984 | - |
Diode assy contains few diodes inside. The first assy model contains three diodes for isolation of three electronic circuits (one of them was a sidestand circuit with its sidestand relay). Later when sidestand relay was abandoned, there was no neccessity for third diode and second generation assy used on newer Virago modles contains only two diodes.

Cut-off relay

41R-83350-71-00 | - | 1992-1998 | 1987-2001 | 1988-1997 | 1986-1999 |
Cut-off relay is one part of flasher assy 41R-71 (second part is flasher circuit). This small relay is used as a relay for engaging the big relay of starter motor. When security percautions are satisfied: the sidestand is up and (gear in neutral position or clutch handle pressed) only then this relay will be activated and starter motor will be able to start the engine.

The starter relay (solenoid) is big power relay. Starter motor (ger. Anlasser) is very powerfull DC motor which starts the engine and loads big current from a battery while starting. The small start switch on handlebar couldn't withstand switching of such a big current for starter motor so it leaves this job to starter relay and is used only for engaging starter relay which furthermore switches the powerfull starter motor.
