Koloi e kanna ea hloleha ho qala. Haeba leqhubu la ho khantša le le phoso, koloi e ke ke ea qala; haeba phepelo ea fensetere ea matla e hloleha, lifensetere tsa motlakase li ke ke tsa ea holimo kapa tlase. Likoloi li na le li-relay tse ngata tse laolang lipotoloho tse fapaneng, kahoo tharollo e itšetlehile ka taba e itseng. A re shebeng matšoao a relay ea koloi e fosahetseng.
Ho fetisoa ha koloi e fosahetseng ho ka lebisa maemong a latelang:
1. Ho qala litaba tsa potoloho: Bula li-circuits moleng oa ho qala, khokahanyo e fosahetseng ea terata, kapa likhokahano tse hlephileng;
2. Litšitiso tsa phepelo ea matla: Betri e shoeleng, li-circuits tse khutšoane tse bakoang ke poleiti ea sulfation, kapa ho se kopane hantle thapong ea motlakase e qalang;
3. Litšitiso tsa motlakase o qalang: Khokahano e mpe lipakeng tsa sepalangoang le borashe, khokahano e fosahetseng lipakeng tsa "solenoid switch" le li-terminals, kapa li-circuits tse khutšoane lebaleng kapa li-windings tsa armature.
Mokhoa oa ho khutlisa relay:
Likoloi li na le li-relay tse ngata le mabokose a fuse. Ka tloaelo, koloi e na le mabokose a mabeli a fuse: e 'ngoe e le sebakeng sa enjene le e' ngoe ka har'a cabin. Ha u bula lebokose la fuse, u tla bona li-fuse tse mebala-bala le likarolo tse ling tse ntšo tsa lisekoere; lisekoere tsena ke li-relay.
Haeba fuse kapa relay e hlōleha, enjene e ka 'na ea se ke ea qala, kapa lisebelisoa tse ling tsa elektronike li ka khaotsa ho sebetsa. Ho li nkela sebaka ho bonolo haholo. Sekoahelo sa lebokose la fuse se thathamisa mesebetsi e tsamaellanang le karolo ka 'ngoe; Fumana feela fuse e itseng kapa relay 'me u e nkele sebaka.
Li-Fuse le li-relay ha li theko e tlaase. Haeba koloi ea hau hangata e ba le mathata a li-fuse kapa li-relay, ho bohlokoa ho boloka li-spares ka koloing e le hore u ka nkela karolo e nang le phoso ka bouena ha bothata bo hlaha.
