T-25 No Spark

Discussion in 'Mechanic and Repair' started by Paradise Yard Service, Oct 20, 2001.

  1. My t-25 just went out on me. No spark. Checked wires/conectors all seem fine. Changed plug/cleaned the toggle switch w. electro cleaner. Still no action. On last use I noticed it had a hard time shutting off. Took a couple tries on the switch to shut down, now it won't start. Help please, as this ol hummer will rip if it only starts.

    i would suggest replacing the switch, one of the contacts could have broken off

    In front of the carb is an electrical connection covered in plastic
    where 3 wires come together. One to the on/off switch, one to
    the ignition module below the carb, and the other one to the
    coil under the engine cover. Disconnect the one going to the
    on/off switch and leave the other 2 connected and see what
    happens. The wire to the switch could be broken and is now touching the metal of the trimmer thus grounding your coil.
  4. A big mahalo (thanks) for the input. I will give these a shot and see what happens. Thanks again.

    That particular trimmer has an igniter on it. I used to have lots of problems with those.
