This is a good place to start:

Do you keep the battery on a tender in the winter months? If not, do so, it will double the life of your battery but something with your charging system is not right.


If you don't have a meter, you can get one for cheap at Harbor Freight. Just remember, you get what you pay for but they are better than none at all.


Rotor (alternator) spins around the stator which creates AC current (alternating current), the AC current (60 plus range in volts ac) goes through a voltage regulator/rectifier where it gets converted to DC (direct current) as well as it gets regulated down to around 13.5 to 14.5 (or close to it but not below) volts.


This 13 to 14 volts DC is what is used to recharge the battery and run the lights, coil, starter, etc.


You need to test each one of the components starting with the stator, disconnect stator wire from regulator and start bike, does it produce ample AC volts when engine is running and at various engine RPM's? If no, then stator or rotor is bad and you have to remove primary cover to determine which (or both) component has failed.


If yes then shut engine off, reconnect stator to regulator and check at the battery terminals with meter set to DC volts. Check voltage at battery before starting, should be 12.7 or more but might not be because it's not charging correctly, then start bike and check volts. Should be 13.5 or more DC volts.


If voltage is lower than this, then your voltage regulator is bad, easy fix (nothing to take apart).


Check your manual and read the link for more detailed instructions, but it is a pretty simple process to diagnose which component is bad. This was just a very brief summary. YD

 

Do you store your battery in a heated area or is it exposed to the cold all winter?

 

Its exposed to the cold

 

Thank you for the advise yankee dog i will try it

 

Fellow SuperLow owner here! You could remove your battery from the bike during the winter and keep it somewhere warm indoors, with a tender to keep it charged. That should give you a much longer life. Also check that your charging system is OK, as suggested by Yankee.

 

Pull the battery and keep it indoors for the winter. Buy a Battery Tender as well, NOT a trickle charger
