Attempting to put up new light fitting & circuit blows

[333rocky333]

Then if the switch that went bang is for the light and wires in your pic.
Refer back to Connys post.
as you now know the switch wire, just test that, no need to part the other cables.
This will establish continuity of the switch as well as the wire.
That was the reason I asked, whether you done that previously

with the power off

Join all the reds together
Seperate all the blacks,
With your dads test meter set the scale to ohms Ω and touch one of the probes to the group of reds.
Now with the other probe touch each black in turn, with the light switch in the off position you will get at least one where you get no reading. (Is it a digital meter or a moving needle meter?)
When you find a black with no reading get your dad to flick the light switch on. (Still with no power on!)
If the meter registers then that black is your switch wire.
