So I got my son a 125 Tao Tao about a year ago, and suddently we cant get it to start or even turn over. Just stopped one day. I replaced the Fuse, and even the key/Ignition cause at the connection the lights would flicker when you move the wires.

but now i cant even get a click when i push the button.
My break lights are one when i pull on them, it is in neutral.
I cannot get it to crank when i cross the solonoid. and i have replaced the starter and solonoid.

Everything turns on as intended but i cannot get it to click when i push the start button. Eben replaced the CDI, ignition coil, fuse. Im stumped.

any help is appreciated.

 

Bad earth from battery to engine?

 

The see im thinking bad ground also, but everything is working except for no start. Im thinking its the safety shutoff. im going to pull it from the wiring to disable it see how it goes. been months of trying to figure this out.

 

Check up under the tank but more towards the rear is there an alarm/remote start on it? If so just disconnect the plug.Also the kill switches in the handle bars and the rear tether go bad since theyre a very cheap switch.Take your cdi plug and remove the kill switch pin and plug it back in this will bypass all kill switches so I would do it with the spark plug out or turn the gas off until it dies if it fires up.

The pin im talking about is the killswitch pin pictured in the first post in this thread which is a very good checklist to diagnose these bikes.
