Electric trimmer won

[Teri]

My Black & Decker Grass Hog 400 Type 1 was working just fine, then it just stopped. No odd sounds, no electrical smell...nothing. Could my on/off switch have blown? Is there a fuse? Is there a reset? I tried another extension cord, and that's not the problem. How do I troubleshoot this? Help, please! Thanks!

Replace the "Brush" (#17) part number 387542-00. Basically they are two sides to the circuit and supply the power to the Armature (with spins) thus completing the circuit. One of the "Bushes" probably blew, I suggest replacing both.
