Hi,
Could anyone give me some advice on methods of testing 12v transformers if at all possible? Why I ask is because been to a customers because one of the under cabinet 12v lights wasn't working. First I tried changing the lamp which didn't work but worked in another fitting. Then just assumed it was the transformer. So swapped it like for like but still didn't work. Then I tested continuity of the cables and IR and they where fine. Checked all connections and they are ok as well tested voltage after the transformer between earth in the JB and the 2 cables which showed as 80v ish? same for the other transformers.
My plan of action is to swap the transformer but I've got the feeling this isn't going to solve the issue.
