If u have a jinlun moped that cuts off when u accelerate it t will be the carb. Or if its leaking fuel its the same problem the carb. has these little needles that will get dirty so ur goin to have to take it apart and clean those needles of. my uncle did it for me it only took hm like 15 min. to get all fixed and put back together. If the moped keeps cuting off ur going to have to check the top of the carb where that little black cover is ur goin to open it and take out that needle and see if its put together right its an easy fix.

My guess (as an electrician specialising in 12v electrical systems) is that the machine is no longer charging the battery for some reason.
A couple of checks:
Connect a fully charged battery, but instead of connecting the earth (negative) side of the battery to the earth wire, connect an ammeter BETWEEN the battery negative and the earth wire, with everything switched off. There should be no current flowing. If there IS a significant current flowing, you have a wiring fault.
With the fully charged battery connected normally, and the scooter on its centre stand, put a digital voltmeter across the terminals of the battery. Record the voltage, which should be between 12 and 13.5volts. Start the engine, preferably with the kickstart rather than the electric starter. Gently rev the engine with all the lights turned off. (be careful that the machine stays on th centre stand and doesn't shoot forward!) The voltage should rise steadily to about 13.8volts. If it shows no sign of rising but steadily falls (especially when you turn the lights on) you have a fault with the charging system, which is either a failed alternator, blown rectifier or a wiring fault. I don't know if the machine has a fuse to protect the alternator - I doubt it.
Hope that helps.
