All electrics gone

t5 mk 1 all electrics just stopped working nothing is on at all what could cause this help needed urgent…

Dose the horn work?if yes,check the rectifier,if not it could be the stator,or the horn is touching the frame?
the blue wire from the stator runs elec,so check that isan’t burnt,then the wire goses to horn and switch,comes back as yellow then goses to the rectifier and out as a yellow/grey wire.
If stuck connect a 6vbattery charger to the two wires from stator (red to blue,black to black) and see what works
hope it helps and dosen’t confuse!
