Here I am again posting about another issue that I am having with my 2009 Blast...this time having problems with the battery.
A few weeks ago I had an old battery that died on me. Would not put enough amps out to start the bike. Push start wouldn't work so I ended up having to jump it was a car that WAS NOT TURNED ON. Driving home I lost all electronics-turn signals, brake light, headlight, you name it-functioning. However, the electronics did come back on about 5 to 10 miles later. Put the battery on a tinder and started right up for the next 10 or so starts. However, the battery again died so I went and bought a new battery at an auto-part store. This battery was purchased on Saturday and Sunday night the battery was once again dead...got a friend with a truck to take me home and put the battery on a tinder and the tinder told me there was no Voltage. Read other threads about charging to 50% and trying to start the bike so I did that and she fired right up. Any suggestions on what could be wrong? I don't think its the battery but something with the charging or wiring situation??? Any help would be awesome thanks.

Good job keeping the car off when jumping.
If the replacement battery takes a charge now, all is good. If not, your stator is probably toast, maybe the voltage regulator (less likely).
Measure voltage at the battery with a meter with the ignition turned on but motor not running. Then measure with the motor running. The latter should be higher then the former (by like 2 volts). If not, it is probably stator or VR.

Your likely culprits are the stator and/or the voltage regulator. The stator is what generates power to keep your battery charged, the voltage regulator acts like dam, it keeps the reservoir (battery) full, then bleeds off excess power.
If the stator is failing, it is not putting out enough power to keep the battery charged, hence you losing the lights and not being able to start. When the voltage regulator fails, voltage can go wild in either direction, if it spikes you start blowing bulbs and damaging the electrical system, but if it sags it is not sending enough power to the battery.
