3. Goga mai fitar da buroshi ba shi da kyau a haɗa shi da na'urar commutator ko kuma matsin lambar mai riƙe buroshin bai isa ba;

4, Kuskuren wayoyi masu lanƙwasawa, polarity a akasin haka;

5, Thejanaretahaɗin goga da zoben zamewa bai yi kyau ba, ko kuma matsin goga bai isa ba;

6. An lalata na'urar juyawa ta stator ko rotor na janareta;

7, Layin jagoran janareta ya lalace ko kuma haɗin maɓallin ba shi da kyau;

Saitin janareta na dizal ba tare da hanyar sarrafa fitarwa ta yanzu da ƙarfin lantarki ba

1, gano fayil ɗin ƙarfin lantarki mai yawa

Juya maɓallin multimeter zuwa ƙarfin DC na 30V (ko yi amfani da fayil ɗin da ya dace da na'urar auna ƙarfin DC), haɗa alkalami ja zuwa ginshiƙin haɗin janareta "armature", sannan haɗa alkalami baƙi zuwa wurin, don injin ya yi aiki sama da matsakaicin gudu, ƙimar ƙarfin lantarki na tsarin lantarki na 12V ya kamata ya zama kusan 14V, kuma ƙimar ƙarfin lantarki na tsarin lantarki na 24V ya kamata ya zama kusan 28V.

2, gano ammeter na waje

Idan babu ammeter a kan dashboard na motar, ana iya amfani da ammeter na waje na DC don gano shi. Da farko cire wayar haɗin "armature" na janareta, sannan a haɗa sandar mai kyau ta ammeter na DC tare da kewayon kusan 20A zuwa "armature" na janareta, da kuma waya mara kyau zuwa mahaɗin da ke cire haɗin da ke sama. Lokacin da injin yana aiki sama da matsakaicin gudu (ba tare da amfani da wasu kayan aikin lantarki ba), ammeter ɗin yana da alamar caji ta 3A-5A don nuna cewajanaretayana aiki yadda ya kamata, in ba haka ba janareta ba ya samar da wutar lantarki.

3, hanyar fitilar gwaji (ƙwanƙwasa mota)

Idan babu na'urar auna mita da mita DC, ana iya amfani da kwararan fitilar mota a matsayin hasken gwaji don ganowa. A haɗa wayoyi masu tsayin da ya dace a ƙarshen kwan fitilar biyu sannan a haɗa abin ɗaurewa a ƙarshen biyu. Kafin a gwada, a cire mai haɗa na'urar "arligature", sannan a matse ƙarshen ɗaya na hasken gwaji zuwa mahaɗin "armature", sannan a ɗauki ɗayan ƙarshen ƙarfen, lokacin da injin ɗin ke aiki a matsakaicin gudu, hasken gwajin yana nuna cewa janareta yana aiki yadda ya kamata, in ba haka ba janareta ba zai samar da wutar lantarki ba.

4, canza saurin injin don lura da hasken fitilar gaba

Bayan kunna injin, kunna fitilun wuta, don gudun injin ya ƙaru a hankali daga jimlar gudu zuwa matsakaicin gudu, idan hasken fitilun wuta ya ƙaru tare da saurin, yana nuna cewa janareta yana aiki yadda ya kamata, in ba haka ba ba ya samar da wutar lantarki.

5, hukuncin fayil ɗin ƙarfin lantarki mai yawa

Bari batirin ya shiga janareta ya yi farin ciki, an haɗa na'urar multimeter da aka zaɓa a cikin fayil ɗin DC voltmeter 3 ~ 5V (ko fayil ɗin da ya dace na na'urar DC voltmeter), alkalami baƙi da ja zuwa ga "ƙarfe" kuma an haɗa ginshiƙin haɗin janareta "armature", ana juya faifan bel ɗin da hannu, na'urar multimeter (ko DC voltmeter) ya kamata ta yi lilo, in ba haka ba janareta ba zai samar da wutar lantarki ba.
