    jika jalur short ,, pasti tidak keluar tegangan kerjanya ...

    jika ketemu yang tidak keluar tegangan kerjanya .. coba inject/ suntik jalur itu dengan PS mengguakan tegangan maksimum jalur nya

    sebagai contoh jalur tegangan kerja V2,85 dig ndak keluar .. pakai PS .. seting tegangan di PS ke tegangan Variabel ..( bisa diubah2 dan mulai dari NOL) .. kabel hitam PS ke ground

    dan kabel merah ke titik ukur yang short ( jangan keliru dengan GROUND) ... lalu naikan teganan PS pelan2 .. biasanya jalur yang short begitu tegangan naik kurang dari setengah

    tegangan kerjanya besaran jarum AMPER akan melonjak tingi
