發電機四根(gen)線需依(yi)據其各自功能，對應連(lian)接到發電機的相應部位(wei)。

不同(tong)類(lei)型(xing)發電(dian)(dian)(dian)機(ji)的四根線功能與連(lian)接方(fang)式有別(bie)(bie)。常見汽(qi)車(che)(che)(che)發電(dian)(dian)(dian)機(ji)的四根線中，勵磁(ci)線為磁(ci)場提供電(dian)(dian)(dian)流，要連(lian)到(dao)(dao)電(dian)(dian)(dian)壓調(diao)節(jie)器；接地線起(qi)到(dao)(dao)接地作用，需連(lian)接車(che)(che)(che)輛金屬車(che)(che)(che)架或(huo)接地端子；指示(shi)燈(deng)線用來(lai)控制充電(dian)(dian)(dian)指示(shi)燈(deng)狀態，按照車(che)(che)(che)輛電(dian)(dian)(dian)路設計(ji)連(lian)接；電(dian)(dian)(dian)樞線負責輸出(chu)電(dian)(dian)(dian)流，連(lian)接到(dao)(dao)車(che)(che)(che)輛電(dian)(dian)(dian)源總線或(huo)電(dian)(dian)(dian)池(chi)正極。還有一種(zhong)情(qing)況，發電(dian)(dian)(dian)機(ji)的四根線分(fen)別(bie)(bie)為B+、N、F、D+，B+接汽(qi)車(che)(che)(che)蓄電(dian)(dian)(dian)池(chi)正極，N接汽(qi)車(che)(che)(che)金屬車(che)(che)(che)身或(huo)底盤(pan)，F接充電(dian)(dian)(dian)指示(shi)燈(deng)，D+是發電(dian)(dian)(dian)機(ji)內部調(diao)節(jie)器一部分(fen)，用于(yu)控制輸出(chu)電(dian)(dian)(dian)壓。

連(lian)(lian)接(jie)發電機四根線，關鍵在于明確(que)每(mei)根線的具體功能(neng)，再按照要(yao)求準確(que)連(lian)(lian)接(jie)。只有連(lian)(lian)接(jie)正確(que)，發電機才能(neng)正常工作，為車輛(liang)等(deng)設(she)備穩定供(gong)電。
