Put a multi tester on the battery terminals set to DC voltage with the engine running and rev the engine. It should rear 13.5 -14.5 volts anything less than 13 means the battery isn't being charged when you ride. It could mean you have a bad stator coil.

Have you tried disconnecting the battery overnight to see if it stays charged away from the scooter? That would eliminate the battery as a cause. Sometimes something new can be faulty. It could be the alarm. According to this guide (link below) you have to hit the disarm or "off" button twice on some of these alarms for them to shut off or they will rearm themselves after a bit. chinesescoots.forumwise.com/chinesescoots-post-75033.html#75033 |

I agree with Fox that disconnecting the battery overnight would be a good start. Then you know for sure if it's the battery or a draw on the system. If it's a draw on the system, the alarm is the most likely culprit. I removed mine from both scoots that had 'em. They were junk on my scoots. Always slowly drained the battery. Never overnight, but there was always some draw on it. Large cable locks to secure the scoot or disc brake locks and things like that are way better security than the alarms anyway IMO. A little battery check info... Here's something else that may be of interest at some point... 49ccscoot.proboards.com/index.cgi?board=igneleclight&action=display&thread=386 |

A quick and dirty test for battery draw can be done with a simple test light (12V). You disconnect one battery terminal and put the light between the disconnected wire and the terminal. The light will light if there is a key off draw. At this point you can disconnect your remote starter/alarm/whatever, and the light should go completely out. If it doesn't then you can start disconnecting stuff, one thing at a time, until it does, and you have found your short.

Works with ANY vehicle...... just with larger stuff you have the luxury of being able to pull fuses until the light goes out.
Folks really good at fixing electrical operate on part experience, part intuition, to many it appears to be voodoo.
If I had to guess, once a voltage draw is confirmed, I would *think* 1) high usage, 2) exposure to the elements (retaining water)
Key switch........ unplug the key switch and see if the draw goes away.
