    With the help of this forum I brought my 1994 Kenworth W900l back to life. Now an endless list of detail work has to be done.
    One problem is, that the truck has no turn lights or hazard. The switch does not show a result. No flash, nothing.
    Where can I start and has a member here a wiring diagram for the turn lights?
    Thanks

    There is a very good chance it is above the panel with the diagnostic port.

    Uploaded the turn/stop lamp diagram. The flasher is just your standard HD 12V negative ground flasher. Paccar P/N would be a CB12050. Its located behind the instrument panel, two wires, red 2ST and Yel/grn L70TN. Good luck and let us know!

    Problem(s) solved. It was a ground problem plus the flasher.

    Most of my electrical problems are found right on the clamps that keep the wires / loom up and out of the way.

    Always find it ironic how the things they add to keep us from having problems are where the problems happen!
