Virago XV750 Running Problem

[[email protected]]

Hi,

I had a problem with my Virago today. She started fine this morning but stopping at a set of lights (yes I do sometimes) the engine just cut out, managed to restart her but she seemed very reluctant to run smoothly unless th rev's were reasonably high and also there was an occansional misfire as if it was only run ning on 1 cylnder. Came out of work tonight and she just would not start and eventually called out Green Flag and the mechanic went over it and eventually got it running although it would not stay running for more than about 30 seconds. He put a meter on the b attery and said that the alternator was only putting out about 10 volts and that was the problem.

Could this be any other problem like a faulty rectifier or is the mechanic correct? Any help on this would be very much appreciated.

Thanks

yes it could be the rectifier at fault, first unplug it and visually check the plug/socket for corrosion or melting

[gizmo666]

could be the coils as well

Should be putting out 14.3 volts to 15.3 volts @2,000rpm. Battery needs to be fully charged to start with. You got a multimeter?

As above

If not the voltage will drop until the engine misfires as the ignition can't produce sparks.
