正確(que)搭線解決車輛(liang)沒電問題，需做好準備、按序連(lian)接并(bing)注意后續操(cao)作。

首先要做好準備工作。拿出或(huo)借取正負(fu)極(ji)各一(yi)根電(dian)瓶(ping)(ping)搭線(xian)，找一(yi)輛(liang)可以供電(dian)的車(che)，兩(liang)(liang)車(che)熄火，打開兩(liang)(liang)車(che)電(dian)瓶(ping)(ping)保護蓋露出正負(fu)極(ji)。確認好電(dian)瓶(ping)(ping)正負(fu)極(ji)，因(yin)為正負(fu)極(ji)一(yi)旦(dan)接(jie)反，可能(neng)會損壞車(che)輛(liang)電(dian)氣系統。

接(jie)著按序連(lian)(lian)接(jie)搭線(xian)(xian)。取(qu)一(yi)(yi)根搭線(xian)(xian)，一(yi)(yi)頭(tou)連(lian)(lian)沒電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)瓶正極(ji)(ji)(ji)，另(ling)一(yi)(yi)頭(tou)連(lian)(lian)有(you)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)瓶正極(ji)(ji)(ji)；取(qu)另(ling)一(yi)(yi)根搭線(xian)(xian)，先連(lian)(lian)有(you)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)瓶負(fu)(fu)極(ji)(ji)(ji)，再(zai)連(lian)(lian)無電(dian)(dian)(dian)(dian)(dian)車(che)輛(liang)發動(dong)機(ji)殼或車(che)身 ，也(ye)就是(shi)負(fu)(fu)極(ji)(ji)(ji)接(jie)負(fu)(fu)極(ji)(ji)(ji)。操(cao)作時要一(yi)(yi)根線(xian)(xian)一(yi)(yi)根線(xian)(xian)進行(xing)，先連(lian)(lian)正極(ji)(ji)(ji)再(zai)連(lian)(lian)負(fu)(fu)極(ji)(ji)(ji)。連(lian)(lian)接(jie)好后(hou)(hou)，啟(qi)動(dong)有(you)電(dian)(dian)(dian)(dian)(dian)車(che)輛(liang)，保持著火運轉，可適當轟油門加快充電(dian)(dian)(dian)(dian)(dian)速(su)度，之后(hou)(hou)嘗(chang)試(shi)起動(dong)沒電(dian)(dian)(dian)(dian)(dian)的車(che)。

最后是后續操(cao)作。若(ruo)車打(da)著火(huo)，要一根一根撤線，先撤負極再(zai)撤正(zheng)極。若(ruo)車無法起動，可(ke)能是電(dian)瓶連(lian)接(jie)線沒接(jie)好(hao)，可(ke)查看夾負極時有(you)無電(dian)火(huo)花(hua)，無則(ze)換地方重(zhong)(zhong)連(lian)；也可(ke)能是沒電(dian)的車電(dian)瓶虧(kui)電(dian)嚴(yan)重(zhong)(zhong)，可(ke)等幾分鐘再(zai)打(da)火(huo)。

車輛沒電并不可(ke)怕，只要掌握正確的搭(da)線方法，就能順利解決問題，讓車輛重新(xin)啟動(dong)。
