正確連(lian)接汽車電瓶線，要(yao)先連(lian)兩(liang)車正極，后(hou)連(lian)負極，且整個過程兩(liang)車都需處于熄火狀態。

連(lian)接汽(qi)車(che)電(dian)(dian)(dian)(dian)瓶(ping)線(xian)時(shi)，要做(zuo)好準(zhun)備工作，找(zhao)一(yi)(yi)輛能供電(dian)(dian)(dian)(dian)的救(jiu)援車(che)，車(che)頭靠在(zai)一(yi)(yi)起，兩車(che)熄火，打開發動機艙(cang)蓋(gai)，拆下電(dian)(dian)(dian)(dian)瓶(ping)保護蓋(gai)，露出正(zheng)負(fu)(fu)(fu)極(ji)(ji)。若無法分(fen)辨(bian)正(zheng)負(fu)(fu)(fu)極(ji)(ji)，就不(bu)能進(jin)行搭電(dian)(dian)(dian)(dian)操(cao)作。準(zhun)備好兩根連(lian)接線(xian)，先(xian)取一(yi)(yi)根，一(yi)(yi)頭連(lian)沒電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)瓶(ping)的正(zheng)極(ji)(ji)，另一(yi)(yi)頭連(lian)有(you)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)瓶(ping)的正(zheng)極(ji)(ji)，正(zheng)負(fu)(fu)(fu)極(ji)(ji)不(bu)能接觸(chu)；再取一(yi)(yi)根，一(yi)(yi)頭連(lian)有(you)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)瓶(ping)的負(fu)(fu)(fu)極(ji)(ji)，另一(yi)(yi)頭連(lian)沒電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)瓶(ping)的負(fu)(fu)(fu)極(ji)(ji)或車(che)身金屬部件(jian)。

連(lian)接(jie)線(xian)搭好后，啟動有電(dian)的救(jiu)(jiu)援(yuan)車(che)輛(liang)。完成搭電(dian)后拆除連(lian)接(jie)線(xian)時，要先拆救(jiu)(jiu)援(yuan)車(che)正極(ji)(ji)，再拆被救(jiu)(jiu)援(yuan)車(che)輛(liang)正極(ji)(ji)，接(jie)著拆救(jiu)(jiu)援(yuan)車(che)輛(liang)負(fu)極(ji)(ji)，最后拆被救(jiu)(jiu)援(yuan)車(che)輛(liang)的負(fu)極(ji)(ji)。整個過程都要格外(wai)注意正負(fu)極(ji)(ji)不要接(jie)反，按順序操作，確保安全。

連接汽車(che)電瓶線需(xu)要嚴(yan)格按照步驟進行，每(mei)個環節都(dou)不容忽視(shi)，才能順(shun)利(li)完成(cheng)電瓶線的連接，保(bao)障汽車(che)正常啟(qi)動。
