Hi everyone, I recently changed my ignition barrel on yamaha ybr 125 2009 there was 1 plastic connector and black/white single wire which i both connected.

After that I switched it on, tried to start my bike and nothing happened horn doesnt work neither do lights or anything else. before i lost my old keys that bike was fully working

there is no rust on battery  or any connectors everything seems ok. anyone have any ideas what could go wrong? any would be appreciated thank you Peter

immobiliser?

no it doesnt have one 

 

Dead battery?

 

As Cynic said first check battery then the switch again and maybe the fuses 

If the ignition barrel and the 2 wires are all you touched, are you sure the new barrel is in good order?

Bad earth.
