Please could a person with vehicle electrical knowledge advise me?
Recently acquired Volvo 240 se number plate lights are not working.
Just replaced the two bulb-holding fittings with genuine Volvo spares and replaced bulbs. Everything appears to be slotted in fine.
There is continuity across them both, and the fuse has continuity. All other lights & electrics appear to be working.
Cannot get a 12V signal across bulb-holding contacts; and the number plate lights don't come on even with engine running and all other lights on.
What is the next step?

make sure all the bulbs are working both the sidelight bulbs and the driving side light bulbs. pull the plugs out of the lenses and check properly.this will cause your problem.

If it is an estate then the cable that comes through the hinge may have fractured. A pain to fix. Regards Peter

Thanks for the replies, Oldman & Peter!
Peter's was the most helpful, I examined the hinge and, sure enough, there was a fractured cable stub which was seemingly impossible to get at. I therefor decided to Tee off from the rear light with some cable to the number plate light: this seems to have worked and the number-plate lights now come on with the other lights.
I've had an old Volvo before; they do seem to go on for ever (Deo volente) 'cept for the 'lectrics.

Volvo electrics are amongst the best you can get. Most of the parts are Bosch. The only reason they give trouble is that the car lasts so long eventually something wears out. Most other cars have been scrapped by then.

Much as I love them, the 240s do have a few points of poor design, and the wires-in-the-hinge is one of the stupidest.
Opinions divide between the purists who buy another proper wiring loom and feed it through the hinge, and those like me who have re-routed all the wires down a length of plastic tube and made an inconspicuous loop between the roof lining and the tailgate.
If you have just bypassed the one wire (lights) so far, be prepared for all the others to fail in due course. The wiper will be next!
