Tried to start my scooter today, and it appears that my battery died, went all the wai down to 8V. Its not the first time it happens, but i've noticed that its not constant, sometimes the battery gets drained, sometimes it doesnt. Already changed the voltage regulator, since i thought that might be the problem, doesnt seem to be helping. I do have an alarm for it, since the starter button failed, so i start it using the remote start on my alarm. How do i troubleshoot the system, so i can find the problem? The stator does work, and it charges the battery when the scooter is running.

This is a common problem. Many scoot batteries have a constant drain. Keep your battery on a trickle charger when not in use. Running the battery down will eventually ruin it. Have the battery tested at a motorcycle shop with a tester built for small batteries.

You noted that sometimes it drains and sometimes not. Can you pay attention to how long it takes to drain? Could be you used it before it had drained, and is actually draining all the time rather than being an intermittent.
I would disconnect the fused items, perhaps remove the fuse, and measure across the fuse holder with an ammeter. You should see very little if any draw, UNLESS you have accessories that are added after factory.
It could be that the remote is using the battery, and draining the power. I had one that would randomly start the engine while no one was around. Could have filled the garage with CO, and made for a messy morning for someone, or could have filled the house... Never did figure out if it was neighbor using a remote garage opener or TV remote or ???, just took the thing off and didn't use it any more.
You could add a non-standard switch, a momentary contact push button, to operate the starter using leads available on the remote connector. One for power to the starter solenoid, or ground, as appropriate. I think they are both on the connector, but if it is wired directly, you could use the ground from the starter button and the power from the brake light switch. Then no remote to eat your battery.
If you do the amp draw check it should be in the milliamp range.
