Need help::2018 taotao atm50 short/fuse blows

[Rocman5190]

Hey guys I need some help. 2018 Tahoe Tahoe 50. I bought it for my son. It automatically blows the fuse whenever you turn the ignition on. I have traced the problem down to the black wire coming from the ignition has short to ground.
Being new to Scooter’s I thought black wire could be ground I’m reading it probably is switched power. Is this true the five wires at the ignition switch our
Red, black green, green black/white tracer.
The solid black has continuity to ground.
Before i go cutting open harness does anyone lnow if black is a ground or its switched power. Cant find any correct wiring schematic for this taotao 50z. Anyone have any luck??..
Ok any help would be greatly appreciated.
