I was riding my scooter home one night when the lights started to flicker and then cut off completely. The bike itself was working fine other than the lights so I parked it and picked it up the next morning to finish my ride home. I had no issues except the lights at the time. A few days later I was riding to work and the scooter started to jolt and jerk then wouldn\'t move and then shut off and wouldn\'t start again. I replaced the battery but now the battery constantly drains and only works for about 24 hours before dying completely again. While the bike itself is still ride-able, the lights still will not turn on but the turn signals and brake lights work. I checked the fuses and they are all fine I also checked the bulbs which also are fine. What is wrong with my scooter?
