My sunrunner scooter works but sometimes when you turn it on it wants to give a jerk before it will go what is wrong with it

W beck you have to remove the seat by pulling it out of of the seat post and then remove the shroud or cover by pulling it straight up You will then be able to see thebatteries. Your scooter equires two 12 volt batteries probably U1 batteries Hope this helps

hi, does it turn off ?

Yes then when you press the lever to go forward or backwards ?is there a click from the rear ?

The controller has got wet ? i can repair those at low cost ..

Regards
Rob

Visit the Manufacturers Website & request an Owners Manual/Download as a PDF File.Please note,carrying out some repairs yourself could leave you stuck.Being repair people may not want to take the job on,not knowing exactly what you have or have not done.But not everyone can afford the bills at times.Take Step by Step pics on a mobile,then you can relate back to them.Starting as you mean to carry on is a good way to go forward in my opinion.As regards the motor (ONLY USE THE CORRECT LUBRICANT,WD40 AND OTHERS SIMILAR CAN CAUSE A SHORT)I hope this helped,Colin.

The centre comes in 2 parts,using a socket set.Use a valve tool to allow all the air out of the inner tube unless,the wheels are solid tyres.

The battery it is dying and it dead and the core of the battery it self can't retain enough the of charge of the electricities for to the battery to move the scooter.Change to a brand new battery ur scooter should work fine.

Hi. Check the battery lead connectors, and the motor lead connectors. I have seen connectors that have melted the plastic because of a bad connection.
Also check the motor brushes to see if they are stuck or worn.
The brushes are held in with black plastic caps. Be carefull doing these up, as they can crack if done up to tight, but they need to be firm.
Good luck. Neil.

no, but batteries could be shot.
