Bathroom light voltage problem


Hi, bathroom light went, thought it was bulb, when new bulb didnt work, checked wiring, wires all frayed, trimmed wires and reconnected, now instead of 220v I'm getting 25v.
Anyone know what could be the problem here

A neutral wire may be loose somewhere in your house (or maybe at the electric panel). Do all the other lights in the house work properly? Does this 25 volts change depending on what other lights and appliances are turned on?

What kind of light is this that requires 220 volts?
Could be bad connection, tripped breaker? The 25 volts might be a false reading if you are using a digital meter.

Change your batteries on your meter and check on a KNOWN LIVE circuit.

All other lights are ok, appliances all ok, breakers all ok. Wire was frayed and damaged, repaired now.
I'm in Ireland all mains lights are 220v.
Meter is ok, have used it ok on other tests.

Is this a digital meter? Try measuring the voltage while the bulb is installed - I'll bet it drops to zero. The voltage reading you are getting is most likely a "phantom" voltage - that happens sometimes with digital meters.

Check all your connections carefully. There's probably a bad one there somewhere.

You must have a bad connecttion some were,
Or perhaps a faulty cable.
Work backwards from the light,
Use a known good volt meter,
Check at lamp sockets first.
Next check at switch.
Then sub panel / fuse,
You will soon find were the problem is.
Please be really careful 220v is deadly,
If you dont feel confident you can do it safely,
then dont do it. Call an electricain.
May I sugest you turn of power,
then instal meter,
then turn on breifily to check meter.
