    As the topic
    safe fuses RAD No.1 and RAD No.2 (with continuity meter), and the radio does not work.
    The radio is removed and there is no tension on the ankle :(
    What's up ??
    Is there a joint on the way?
    I would like to add that everything else works, and it happened so suddenly, just one morning dark / dull.

    Rather the other is not, because half the car would not work, and everything works rather.
    The worst thing is that access to fuses is a nightmare, and I will check the meter for fuses today

    Use a standard bulb to check the fuses.
    One pole to ground - the other one applies successively to both fuse pins.
    Of course, the light bulb shines on both fuse leads.
    Helpful post? Buy me a coffee.

    the fuse has the correct voltage (so far the meter),
    so there must be a connector along the way or the cord has been damaged, but how?

    thanks
    I have already had this diagram for a long time and it does not say anything to me anymore, because everything has already been checked out, free. Tips 1 and 2
    I have a question where is the J8 connector located?
    just what makes me wonder
    there are two circuits + B and ACC from different modes and on both there is no voltage
    what is?
    and the car is burning, driving and braking :)

    Check the circuits with a light bulb as CameR advised.

    According to the scheme, B + should go directly, one cable without connection from the fuse to the radio.

    the mass is.
    the backlight does not work because there is no power supply as it is written
    B + goes through the CE-CB connector and two fuses (RAD 2 safe)
    radio before FL (2003) or W53901

    The matter resolved, it's better not to write :( obciach
    The power supply turned out to be, because I was suggesting the colors of the wires, and that the frost and poor weather conditions were approaches were in a hurry and a nervous condition :)
    Radio removed, dismantled, soldered suspicious February and the game.

Topic summary

The discussion revolves around an unexpected power loss in the radio of a Toyota Avensis T25 1.8. The user reports that after checking the fuses (RAD No.1 and RAD No.2) with a continuity meter, the radio remains non-functional despite other car systems working. Suggestions include checking additional circuits, using a light bulb to test fuses, and investigating potential wiring issues or connectors along the power path. The user later identifies that the problem was due to damaged wires caused by adverse weather conditions, which were repaired, restoring functionality to the radio.
