1, multimeter ƙarfin lantarki gane fayil

Juya kullin multimeter zuwa ƙarfin lantarki na 30V DC (ko amfani da fayil ɗin da ya dace da voltmeter na DC), haɗa alkalami ja zuwa ginshiƙi na haɗin "armature", kuma haɗa alƙalamin baƙar fata zuwa mahalli, ta yadda injin yana gudana sama da matsakaicin gudun. , Matsakaicin ƙimar wutar lantarki na tsarin lantarki na 12V yakamata ya zama kusan 14V, kuma ƙimar ma'aunin wutar lantarki na tsarin lantarki na 24V yakamata ya zama kusan 28V.

2, gano ammeter na waje

Lokacin da babu ammeter akan dashboard ɗin motar, ana iya amfani da ammeter na waje don ganowa. Da farko cire janareta "armature" mai haɗa waya, sa'an nan kuma haɗa tabbataccen sandar DC ammeter tare da kewayon kusan 20A zuwa janareta "armature", da kuma mummunar waya zuwa mai haɗin haɗin da ke sama. Lokacin da injin yana gudana sama da matsakaicin matsakaici (ba tare da amfani da wasu kayan lantarki ba), ammeter yana da alamar caji 3A-5A don nuna cewajanaretayana aiki akai-akai, in ba haka ba janareta ba ya samar da wutar lantarki.

3, Hanyar gwajin fitila (kwalbul na mota).

Lokacin da babu multimeter da DC mita, za a iya amfani da kwararan fitila mota a matsayin gwajin gwajin gano. Weld wayoyi na tsayin da suka dace zuwa ƙarshen kwan fitila kuma haɗa madaidaicin alligator zuwa ƙarshen biyun. Kafin gwaji, cire madugu na janareta na “armature” connector, sa'an nan kuma matsa daya karshen hasken gwajin zuwa janareta "armature" connector, da kuma dauki daya karshen na baƙin ƙarfe, a lokacin da engine yana aiki a matsakaici gudun, Hasken gwaji ya nuna cewa janareta yana aiki kamar yadda aka saba, in ba haka ba janareta ba zai samar da wutar lantarki ba.

4, canza saurin injin don lura da hasken fitilar kai

Bayan an kunna injin ɗin sai a kunna fitilun mota, ta yadda saurin injin ɗin ya ƙaru a hankali daga jimlar gudu zuwa matsakaicin gudu, idan hasken fitilun ɗin ya ƙaru da gudu, yana nuna cewa janareta yana aiki bisa ga al'ada, in ba haka ba ba ya haifar da. wutar lantarki.

5, multimeter ƙarfin lantarki fayil hukunci

Bari baturin zuwa janareta ya yi farin ciki, multimeter da aka zaɓa a cikin wutar lantarki na DC 3 ~ 5V (ko fayil ɗin da ya dace na babban voltmeter DC), baƙar fata da ja alkalami an haɗa su zuwa "ƙarfe" da kuma janareta "armature" shafi shafi. , jujjuya faifan bel da hannu, ma'aunin multimeter (ko DC voltmeter) ya kamata ya juya, in ba haka ba janareta ba zai samar da wutar lantarki ba.
