Hi,
I conducted an EICR last week on a three bed property with a large extension.
I have just emailed the customer with a proposal to fix the repairs. SWALLOWS HARD!!!
Originally I recommended a rewire as I did not want to give a fixed price for the repair work and the customer seemed unhappy to work on a rolling contract. I have no idea how long this wil take to repair as the fault could be anything anywhere.
One of the 80 volt readings was spotted at the time of the EICR but the other was not and I only spotted that today when I fitted a dimmer switch. When operating the dimmer the lamp would come on and go off after a couple of seconds. Its a Varilight IQ remote controlled dimmer switch. Its on a one way circuit.
With the dimmer in the off position I was reading 240 volts yet the lamp would not illuminate. Replace the lamp and despite 230volts it would not come on. So switch the dimmer "on" and well it just reads 240 again the same as the off position. Replace the lamp and it comes on for between 2 and 4 seconds before going off and then randomly coming on and off.
I tested for loose connections and fluctuating voltages and polarity but no joy. The fitting part of the pendant was hanging by a thread on the neutral originally which I could hear sparking inside!!! I replace this but it didn't make any difference. All terminations were sound including the switch.
Any help greatly appreciated. Hoping to go back and get amongst this job as I'm sure theres a lot to be learnt, just maybe not the most profitable job in the world. I do feel finding the ring circuit fault could be a nightmare too so if anyones got any tips please divulge!!
Ive got a strategy lined up and if I win this work I will be posting back and forth here for help if it goes ---- up.

I conducted an EICR last week on a three bed property with a large extension.
- Broken earth on two lights downsatirs
- No ZS readings possible on the upstairs lighting circuit at any of the accessories. Switch drops wired in twin red no earth.
- Ring main no continuity >2000 ohms on all conductors
- Ring main 0.03 N-E 0.13 L-E 6.6 L-N IR readings
- 80 volts on switch wires of two seperate circuits
- 70 volts on ring earth
