Friends,
have had charging issues on my 2008 busa for a while now.
I have done the following.
1. checked all connections.
2. Gone through 5 rectifiers and now have bought a brand new coil.
When the bike idles for long and the two fans come on, the voltage accross the battery gradually drops till it eventually gets to about 12.1-12.2v and by this time if you shut down the bike and start, it will not start.
From my haynes manual , i read the following - Generator voltage on a no-load situation when cold should be 70v (alternating) and more at 5000rpm . I really dont understand what this means . Is it that when the bike is idling, it should be 70v and when you rev up to 5000rpm it should give you more voltage . My brand new coil when it idles , it produces 24v and when at 5000rpm its about 90v.
Any suggestions or help will be appreciated .
Thanks .
