Battery keeps losing its charge

-Nothing will last. Keep charging when it's low.

Good luck

More likely to be your ignition coils. They heat up and expand this can cause an open circuit which will close up again when it has cooled down. Although, a bad charging system may cause this problem. Check the battery voltage with engine switched off ( approx 12 volts) and with the engine running (approx 14 volts) If you are getting 14 volts then your battery is dead, if you aren't, then your charging system has a fault.

Sounds like you are not getting a charge from the alternator. You need to check battery voltage with a meter with the engine off, key off. Then again with it running, and the voltage should increase. If not, it's not charging.

You will have to check the charging rate of your bike, normally it should give an output of around 13.8Volts to 14Volts.
If the readings are lower thn tht, thn there is a problem in the bike's charging system.
Hope this helps!

It sounds like the battery may be bad in spite of Auto-Zone's pronouncement. The connectors to the battery may be bad enough to make a poor connection to the battery posts. Is the battery water level up to the line in each cell?
Re-jet one step bigger as the baffle removal will make it run lean.

This is a common problem with chinese atvs. I installed a toggle switch on the positive wire from the battery. When my daughter is finished riding, I simply flip the switch and all power to the bike is killed, preserving the battery.

sounds as if you have an issue with the charging system, try using a volt meter to determine if the bike is charging. To do so you will need to access the battery under the seat, with the bike running hook up the volt meter to the battery terminals, at idle you should have around 11volts when reving you should have around 13volts. If not you may have a bad stator or other electrical issues. good luck

Don't rely on on whether the bike will start at a gas station to determine if the charging system is working. Get the multimeter out and do a proper test. Should be getting about 14.5 volts @ around 3K RPM. It's too easy of a test to to just skip. If it is charging then start looking for something else. Was the new battery properly charged to begin with? Loose battery connection? I suppose the GPS could be too much but you said that it was dying last november, so I would suspect something else. P.S. you need a properly charged battery to get an accurate reading for the charging test.

though if it was a problem it would have blown the 10amp fuse????Don't rely on on whether the bike will start at a gas station to determine if the charging system is working.

came out of the coffee shop went to start the bike and the battery didn't have enough power to turn over the motor....I pushed started it but it didn't want to stay running once I put it in gear. Last night charged the battery and today put it in the bike and it started right up....rode it for about 45 minutes waited for about half an hour before starting it up again and it started , no problem. I am thinking that maybe it is the voltage regulator or maybe the alternator....can anyone help me out with this? ,If you have a multimeter, you need to test the electrical output of the charging system. (Check the voltage of the battery when the bike is revving at about 2000 rpm) If you don't have a multimeter, the best thing to do probably is to take the bike to an Autozone or similar car place where they will test the battery and charging system for free,,,
