Just to be correct there is only one earth(from the battery to the frame)?

If there is more could someone tell me please
Probably more than one, I'm guessing frame , engine, rectifier, fairing sub-frame? The wiring diagram above should show them.

You need to provide volts to power the ecu etc which a battery will do until it runs flat... assuming the engine has the alternator still installed, you just need to connect that to a rectifier to keep the battery charged.

I have the alternator installed but don’t have a rectifier so I can’t use that but even without that the screen doesn’t light up until I put power to another plug, I will video to show what I mean

You'll just need the rectifier once you get this project running meantime a battery will be fine.

Okay brilliant I will get one at a later date, I just need to fine the earth wires for sale as that’s the problem why nothing is lighting up. If I put a wire from the negative on the battery and then to the frame the clock lights up but displays nothing

Do you have the black/white stripe wire from the loom connected to the battery neg, too?
