What method/instrument did you use to test for voltage at the pendent.
As there are various voltage reference points that can be tested depending on the way the rose has been wired, that will indicate voltage, even if the lamp dose not work.
Also a non-contact or single point contact indicator, will not give conclusive results and are often misleading.
The best instrument for testing for voltage, is a two probe/pole indicator.
Such as this

And testing with switch between closed:
Switch live-Neutral for approx 240V
Switch live-Earth for approx 240V
Neutral-Earth for 0V
Should indicate whether you have power to the fitting.
Continuity would be the safest method to test before testing live though.
This would be done with the circuit isolated and for increased safety the board isolated. By removing and connecting both Line and neutral of the circuit together at the board, then testing at switch live and neutral at the fitting with either lamps out, should identify continuity of the two conductors, also using the same process between line and earth, neutral and earth with the switch closed, will do the same. If one is out the results of the these three tests should indicate which one it is.
Note: Have checked your wiring is correct and that the lamp is in good working order?
