12 volts sockets

[Fugereri]

In my Tuscany, There are three 12 volts sockets.
When i verified them with a tester i have 12 volts but none of my devices will work in any of those sockets.... i tried an i phone, an iPad, a GPS and a brake controller, none work. I tried with the ignition switch on, with the motor running... they never work
Any help will be greatly appreciated

So what doesn't work? Do any of your devices have a "Power Available" LED on the part that goes into the 12 volt socket? Does that not come on? Are you sure you are pushing them in far enough for the end to make contact?

There is a chance that you could have a corroded connection in the supply line to the sockets. That would allow you to measure 12 VDC under no load conditions but as soon as you have a load (current) the 12 volts is dropped across the corroded connection.

If you have a device plugged into one socket, do you still have 12 VDC at the other 2 sockets?
