so I've tried to replace the bathroom light fitting today but there is a crazy amount of wires and I'm confused.com what's worse is that now half the upstairs lights aren't working and the mrs is fuming - please help! There is one switched live, 4 earth, 4 live and 3 neutral. usually I just mirror what the old fitting had but if you look at the pics of the previously fitted light, the neutral and live are in the opposite terminals - crazy. Can anybody point me the right direction? Should it matter if all the neutrals and the live are in the same terminal?
