Hello, I have a non running Cosaro 125cc and I have trouble with the electrics. I would like to know if the bike is negative earth and what colour is the earth wire? If I could get any information such as a wiring diagram or manual that would be great.Thanks

This is the schematic of the electric wiring of the Corsaro 125cc and 150cc.
Hope this helps.

To 350-v-twin, Brilliant, that will get me up and running! Thank you so much.

My pleasure and good luck!!
