Problem with positive current cable brown/red

When adding an automatic electric antenna, everything worked fine,  but when putting back the radio it no longer worked, I think that the positive cable after the ignition key should have come loose. I imagined it must have touched ground and blown a fuse, but no, all fuses are fine.

I found the wire that should be the brown / red one and I located it in the fuse box but it has no current (First photo indicated with orange arrow).

I took out the connector (First photo) where current should pass and I checked it with ground and touching each terminal one by one and it does not give me 12 v.

I have been with this for several hours and I cannot find the solution or think of anything else. Can you guide me how to continue?








I want to take the opportunity to change the burned-out heating bulb and I don't know how to get it out, can you help me with this too?

There's no pics. I am guessing cabby, I am not 100% sure there is a convenient ignition-live at the back of the fusebox but there's plenty of info online of what the extra available connectors do. If you are still struggling, let us know and I'll try find the info.

You're right. Sorry for the inconvenience. I have edited my answer by uploading the photos

The arrowed connector,  how many brown/red wires are connected to it? Just the one or are there two. Have you got any more brown/red wires by the radio?

In the connector with arrows you only have a brown / red one. This is the same for radio.
Checking the continuity of the cable, it is the same that goes from the connector to the radio and has no current to give positive to the radio.
Do you know what the fuse can be?

The brown/red is not fused. The power(current) comes from the ignition switch. If you remove the covers from around the ignition you should see the wire. Test for power there. The wire then goes to the radio and continues to the fusebox. The join is usually made at the radio or the fusebox that why I asked if there was any other brown/red wires. The wire goes to the fusebox for electric roof (hood) if you have one. It's possible the join could have been made in the wiring loom. If you test the brown/ red at the ignition switch, it should have power with key in the ignition.
Hope this helps,  Steve.

For the heater control bulb…..

In the end I did not get it to work with the brown/red wire so I went to plan B.
I think the problem is in the ignition key.
I have taken positive from the blue / black wire that goes to the rear window heated switch because it is a positive after contact.
Thanks everyone for your help
