Replacing some very old halogen transformer spotlights with newer ones that can take LED bulbs. It’s a timely job too as a few of the transformers look like they’ve melted.
I’m stuck now though because the old wires that ran into the transformer are both brown wires - no way to tell if one is live and one is neutral (which seems to be required by the new fixture). Is there anyway to tell which is which so I can fit the new one?
