Was this bike running when you got it ????
I presume it is a positive earth set up and the red wire is the positive, but you battery show no wire to earth the battery which means there is no way anything on this will work as there is no connection between the battery and regulator which means it would never charge the battery or power the ignition box as there is no circuit. I would think there should be a connection between the two 20 amp fuses to the negative of the battery which I believe the brown wire to be.
The right switch appears to be switching the earth to operate operate relay one. This is turning on the power for the ignition and switching the earth to power up relay 2.The fuse on relay 2 is in the wrong side of the relay
There is so much wrong here I would think your safest route is to have the unit rewired properly and switch it over to negative earth. It is very easy to do on Alternator powered bikes.
Judging by the diagram the person got positive and negative earth mixed up half way through his rewiring job.
On older bikes the power line is always switched not the earth as the risk of shorting out positive and negative is to high.
The newer ECU drive bikes and cars switch an earth to power up circuits controlled by the ECUs.
I have seen many blow ECUs over this when they did not realise it.
I live in the south of Ireland and unless you live in Ireland I cannot help you to rewire it.
