    7346 with 004-338 error

    Hello all,

    I'm stuck on a 7346 that is showing 004-388 error on the top of the screen but is not recorded in basic fault log. In order to see it recorded anywhere I have to go in to diagnostics and its the only error showing there. My edocs pointed me toward replacing the I/f mdd pwb which has 5 glass tube fuses on it. I replaced this board, finding the top left fuse blown only to have it happen on the new board with two different fuses.

    Any ideas and input on this is appreciated. I have a very angry customer on my hands right now.

    Thanks.

    Follow the wiring diagram and find out what the fuse does! Check for a short in the circuit.
