Have 1983 Yamaha Virago 550. The previous owner has jerry rigged the wiring on it to the point there is a mitsubishi electrical component on the left hand side opposite to the battery. Now having stated all that, I'm not sure that his ingenuity really has any to do with the problem. The problem: I can jump start the bike with jumper cables, but as soon as I disconnect and try to ride the bike dies and will not start until jumped again. Battery checks out to be good. I was told to possibly check the stator or charging coil? Hopefully this is in depth enough for someone to make any sense of and good willingly be of some help....Thankyou..
Hi and welcome to FixYa,
Offhand, even if the the stator / charging coil is defective or for that matter even the regulator, the bike should start and run on a fully charged battery. The only problem would be that the bike would die eventually. If haven't been tried, have the battery load tested not just voltmeter test.
Please postback after the load test. Hopefully by then, I would have the wiring diagram.
Good luck and thank you for asking FixYa.
