1200 (1985) Goldwing. Stator has been replaced, new battery. Battery don't stay charged. Boost or trickle charge to get it running. Run till it reaches 14v then next day battery is dead or not enought voltage to turn over bike. Do anyone have a suggestion?
Brian, we basically need a little more information.
Do you ride the bike after the battery charge or does it go dead just sitting there after a full charge?
You might try charging the battery, then disconnecting it (wait a while for the battery to gas off before disconnecting so a spark won't blow you up).. If that battery stays up you then have a parasitic draw on your system. If the battery still goes down overnight then you probably have a bad battery.
If you have a parasitic draw, try disconnecting the positive battery cable, then placing a 12 volt test light between the removed cable & battery post. If the light lights up start pulling fuses until the light goes off. Whatever is on that fuse circuit is causing the draw.
You might have your battery load tested at a local bike shop (most have a small load tester on site).
More info from you (like when it started? how long has it been happening? What else has been done? What is the battery voltage while riding at 3000-4000 RPM's? Anything else you can add sure would help up help you further.
