I had an extension built and electrician fitted low voltage lights.
Lights flickered so I changed them to the spot lights that worked
direct from mains, with no need for a transformer. Changed most of
them a year ago and then went to change the final 4 today. No problem
with 3 of them as merely copied what I had done previously.
Got to the fourth, nearest the switch and it had a junction box with
three wires. Disconnected the box without recording what connections
Looked at the various wiring diagrams on the net and worked out that
the three reds needed to all be connected to each other. Closed off
the three earths. Then turned to the three blacks. Guessed which Black
came from the switch, connected this to the live for the light, and
connected the other two blacks to the neutral for the light - guessed
wrong so fuse blew.
Swapped blacks and this time lights stayed on permanently and switch
didn't turn them off and on. Swapped blacks again and this time one
light goes off and on when turn switch, but all other three stay on.
Any one any bright ideas as am running out of fuse wire.
