Tips required for fault finding on track lighting.

[GBDamo]

The track in question is Eutrac single circuit (i think) and the offending fitting is hung from one of these.
EUTRAC - https://www.eutrac.de/3/262/en/products/~1_multiadapter_with_data_bus_option

There are three pendant fittings on this one particular section of track; the one either side of the suspect one works.

There is no voltage at the GU10 lampholder

The suspect one does not work when moved elsewhere on the track.

Others Pendants work when put in the position of the suspect one.

Finally, there is no voltage at the pendant terminals in the adaptor.

My thoughts are the adapter is kaput but looks fine.

The job is quite a trek and don't want to order, wait for delivery, trek up there only to find it doesn't resolve the fault.

Anyone had experience of these systems and if so are there any common faults to look out for?

Ta in advance.

Done any form of testing?

Why bother then?

Yes plenty, as detailed above, please advise if you can think of something else that is required, relevant and time efficient.

Those that aren't such a trek are very profitable, those that are are a necessary evil to keep customer sweet and the contract with us.

How much is it? And are the old lamp contacts burned out?
I think it is a safe bet as to what you have done so far your assumtion will solve your problem.

Who tested the fitting for no voltage at fitting? it could be as simple as a switch on the side of the adaptor. Failing that the contacts not making I would take a new fitting rather than a 2nd trip.

Not expensive, the lamp holder contacts are pristine unlike some of the other fittings. I'm fairly sure it's the adapter but you never can tell.

I Did the testing, first with a Kewtech AVI then confirmed with the MFT, there is zero Vs.

I hadn't noticed a switch but will certainly look out for one.

Found the mother load, could be someone has been fiddling and it is connected to the wrong track.

If all else fails RTFM

The suspect fitting is NFG.

It’ll be the contacts to the bus bar in the track. You won’t pick up voltage at the GU10 because it’s not getting there. Long nose pliers on the contacts and test that the mechanism enables them to make contact.
It happened to me and I wasted 20 mins of my life on it! and it was new!

That sound likely, will look at that too.
