如何解(jie)決叉車電瓶有電卻無法啟(qi)動(dong)的(de)問題？

　　一、叉車(che)電(dian)(dian)池充電(dian)(dian)，但打不著(zhu)火(huo)，鑰(yao)匙(chi)點火(huo)啟動(dong)電(dian)(dian)機無反應。修理方法(fa):檢查發(fa)動(dong)機是(shi)否(fou)(fou)有缺陷，線路或電(dian)(dian)池接觸(chu)不良，電(dian)(dian)量不足。檢查安全(quan)板是(shi)否(fou)(fou)正(zheng)常，鑰(yao)匙(chi)開關是(shi)否(fou)(fou)突出(chu)。假(jia)設前面幾點正(zheng)常，測量檢查電(dian)(dian)池電(dian)(dian)量是(shi)否(fou)(fou)高于12.5V。如果電(dian)(dian)池老化，請更(geng)換新電(dian)(dian)池。

　　二，鏟車(che)有電，有油，有氣(qi)，還是打(da)(da)不著火。修理方(fang)法:首先打(da)(da)開(kai)(kai)發動(dong)機罩(zhao)，拉出分電器核心處的高(gao)壓線，在距離(li)氣(qi)缸體6、7 mm處打(da)(da)開(kai)(kai)燃燒開(kai)(kai)關，然后點(dian)火使曲(qu)軸轉動(dong)，檢(jian)查(cha)高(gao)壓線產(chan)生的電火花(hua)。然后拆下所有火花(hua)塞并(bing)檢(jian)查(cha)是否損壞。如果是柴油車(che)，檢(jian)查(cha)高(gao)壓油泵噴油是否正常，噴嘴霧化是否正常。

　　三，如(ru)(ru)(ru)果(guo)沒有火花，檢查線(xian)路(lu)(lu)的(de)原因(yin)是(shi)(shi)低(di)壓(ya)電(dian)(dian)(dian)路(lu)(lu)短路(lu)(lu)、開(kai)路(lu)(lu)，或者燃燒線(xian)圈、鐵芯高(gao)壓(ya)線(xian)有缺陷(xian)。可以(yi)交替打(da)開(kai)和閉(bi)合觸(chu)點，以(yi)調(diao)查萬用(yong)表(biao)指(zhi)(zhi)針或數字(zi)讀數是(shi)(shi)否正常(chang)。如(ru)(ru)(ru)果(guo)電(dian)(dian)(dian)流(liu)(liu)表(biao)指(zhi)(zhi)示放電(dian)(dian)(dian)持(chi)續3~5 A，并間(jian)歇抖(dou)動，則(ze)表(biao)明低(di)壓(ya)電(dian)(dian)(dian)路(lu)(lu)突出(chu)，故障是(shi)(shi)由高(gao)壓(ya)電(dian)(dian)(dian)路(lu)(lu)引起的(de)；如(ru)(ru)(ru)果(guo)電(dian)(dian)(dian)流(liu)(liu)表(biao)指(zhi)(zhi)針不晃動，說明低(di)壓(ya)電(dian)(dian)(dian)路(lu)(lu)有開(kai)路(lu)(lu)；如(ru)(ru)(ru)果(guo)電(dian)(dian)(dian)流(liu)(liu)表(biao)大(da)電(dian)(dian)(dian)流(liu)(liu)放電(dian)(dian)(dian)，說明低(di)壓(ya)電(dian)(dian)(dian)路(lu)(lu)存在接地缺陷(xian)。如(ru)(ru)(ru)果(guo)是(shi)(shi)柴油(you)車，檢查高(gao)壓(ya)柴油(you)泵的(de)電(dian)(dian)(dian)磁閥工作(zuo)是(shi)(shi)否正常(chang)，有無正常(chang)電(dian)(dian)(dian)壓(ya)進入電(dian)(dian)(dian)磁閥。如(ru)(ru)(ru)果(guo)不是(shi)(shi)，檢查電(dian)(dian)(dian)路(lu)(lu)，確保(bao)安全。

　　四。如果火(huo)花(hua)太強(qiang)，產(chan)生藍白色火(huo)花(hua)，說(shuo)明低壓(ya)電路(lu)和燃(ran)燒線圈突出(chu)，缺點在分電器(qi)(qi)和火(huo)花(hua)塞(sai)的高壓(ya)電路(lu)。從火(huo)花(hua)塞(sai)上端(duan)拆下高壓(ya)線頭(tou)，轉動曲軸測試機(ji)體的著火(huo)情況。如果沒有著火(huo)，檢(jian)查分電器(qi)(qi)、分電器(qi)(qi)蓋(gai)和高壓(ya)分電器(qi)(qi)是否漏電，如果有火(huo)花(hua)，檢(jian)查燃(ran)燒正時和火(huo)花(hua)塞(sai)的工(gong)作情況。
