You will need to replace your solenoid. Just keep tapping your start button while looking for the source of that clicking sound. When you locate the solenoid you should have 3 to 4 wires to remove. I suggest you take a digital snapshot of it before removal so you can remember how to reinstall the new one. A generic solenoid is all that is needed to get you up and running, and these can be found in most any motorcycle shop.

Electric start doesnt seem to be working

If there's no noise at all your battery is either dead (jump start or new battery). If it clicks then there isn't enough charge in your battery to start the bike (charge battery or bump start)

Problem with Geely 50cc scooter's alternator? Please help!

If you have a friend who wears a hearing aid with a telephone pickup coil, the test is very easy. Have your friend switch the hearing aid to the telephone position, then listen to the engine while it is idling with the clutch disengaged. Accelerate the engine and let it return to idle. Your friend should hear a rapid ticking noise from the spark plug and a whine from the alternator that goes up in pitch when the engine runs faster. If he hears the ticking but doesn't hear the whine even at low speed, have him listen closer to the battery or alternator. If he still doesn't hear it, the alternator is probably not working at all. (I use this technique quite often to find ignition or alternator faults.)

If you have a voltmeter, measure the battery voltage when the scooter is not running. It should be at least 11.8 Volts. Start the scooter, and with the clutch disengaged, speed up the engine while monitoring the battery voltage. It should increase with engine speed, up to 14 Volts. (Do not run the engine for a long time at high speed with the clutch disengaged. Lack of cooling airflow or overspeeding may damage the engine.) Alternatively, turn on the headlight and see if it gets brighter with increased engine speed. If the battery voltage stays low and the headlight doesn't work or is dim at any speed, the alternator is bad.

The usual failure modes causing low or no output are a faulty regulator, worn brushes, or failed rectifier module. It is sometimes cheaper to repair the alternator than to replace it, if you know how to take it apart and put it back together. (The biggest trick is to use the brush access holes to pin the brushes away from the commutator during assembly; once everything is together, remove the pins to let the brushes contact the commutator. I use a pair of small nails for the pins.) You may be able to purchase a rebuild kit from an automotive or motorcycle parts store.

Note: if most of your scooter operation is at low engine speed, the alternator may not turn fast enough to fully charge the battery. If it is not practical to occasionally run at a higher speed, you may need to obtain a 12 V battery charger (at least 1.5 A output) to fully charge the battery when the scooter is at home. Also, if you receive an empty new battery and have to pour the acid in to use it, follow the directions and let the battery sit for several hours before charging it, then install it. If you don't do this, the new battery won't last very long.

I have a 50cc sunl scooter, and i cant put it bac in time

with the spark plug out and the valve cover removed; place a screwdriver into the spark plug hole; turn the crankshaft until the valves are all the way up and, not moving as the piston just starts to go down in both directions; (use the screwdriver to see this) this is TDC or, top dead center now; you should see symbols on the faces of the cam gear and, the crank gear and, two places on the chain; line up the chain symbols with the gear symbols chain symbols facing out and, install the chain.
by the way they make a kit for stripped sparkplug holes an auto parts store will have it in case you need one again.
