2.啟(qi)動(dong)器(qi)不(bu)工作：當鑰(yao)匙(chi)啟(qi)動(dong)開關打到啟(qi)動(dong)位(wei)置時，鑰(yao)匙(chi)開關的啟(qi)動(dong)(R2)端(duan)應(ying)有(you)電(dian)源輸(shu)(shu)(shu)(shu)出(chu)。 若無輸(shu)(shu)(shu)(shu)出(chu)，則按鍵開關損壞；按鍵開關起(qi)始端(duan)已輸(shu)(shu)(shu)(shu)出(chu)到起(qi)始復合(he)(he)繼電(dian)器(qi)后，測(ce)量起(qi)始復合(he)(he)繼電(dian)器(qi)是否(fou)(fou)有(you)輸(shu)(shu)(shu)(shu)出(chu)。 如(ru)(ru)果輸(shu)(shu)(shu)(shu)出(chu)沒有(you)兩個原(yuan)因(yin)：（1)起(qi)動(dong)復合(he)(he)繼電(dian)器(qi)損壞；(2)起(qi)動(dong)復合(he)(he)繼電(dian)器(qi)中點(dian)信號(hao)(hao)(hao)端(duan)電(dian)源電(dian)壓(檢查(cha)中點(dian)信號(hao)(hao)(hao)端(duan)信號(hao)(hao)(hao)輸(shu)(shu)(shu)(shu)入是否(fou)(fou)有(you)帶電(dian)源短路現象或起(qi)動(dong)器(qi)中點(dian)輸(shu)(shu)(shu)(shu)出(chu)異常(chang)）。如(ru)(ru)果起(qi)動(dong)復合(he)(he)繼電(dian)器(qi)輸(shu)(shu)(shu)(shu)出(chu)正常(chang)，檢查(cha)起(qi)動(dong)復合(he)(he)繼電(dian)器(qi)輸(shu)(shu)(shu)(shu)出(chu)端(duan)與起(qi)動(dong)機(ji)之間的線束(shu)連(lian)接是否(fou)(fou)完(wan)好(hao)（測(ce)量起(qi)動(dong)機(ji)端(duan)起(qi)動(dong)線是否(fou)(fou)有(you)電(dian)壓）；如(ru)(ru)果上述情況(kuang)完(wan)全正常(chang)，可判斷起(qi)動(dong)機(ji)不(bu)能正常(chang)工作。

注：以上分析判斷企(qi)業必須是在其它(ta)經濟條件完(wan)全(quan)可以正常的(de)情況下我們才能通過(guo)成(cheng)立，若系(xi)統工作電(dian)(dian)(dian)(dian)壓水(shui)平過(guo)低(di)也(ye)會造成(cheng)影響起(qi)動(dong)機不能直接起(qi)動(dong)的(de)情況。挖掘(jue)機修理(li)人員(yuan)不能熄(xi)火當鑰(yao)(yao)(yao)匙(chi)(chi)起(qi)動(dong)控制(zhi)開(kai)(kai)(kai)關(guan)(guan)(guan)打(da)到(dao)關(guan)(guan)(guan)閉(bi)(bi)一(yi)個位置時挖掘(jue)機修理(li)技(ji)術不能熄(xi)火，請檢查(cha)在鑰(yao)(yao)(yao)匙(chi)(chi)關(guan)(guan)(guan)閉(bi)(bi)狀態熄(xi)火電(dian)(dian)(dian)(dian)磁閥保持線圈控制(zhi)線是否(fou)有(you)電(dian)(dian)(dian)(dian)，如果沒電(dian)(dian)(dian)(dian)，那么(me)是熄(xi)火電(dian)(dian)(dian)(dian)磁閥壞，更換即可；若有(you)電(dian)(dian)(dian)(dian)，測(ce)量(liang)鑰(yao)(yao)(yao)匙(chi)(chi)開(kai)(kai)(kai)在關(guan)(guan)(guan)閉(bi)(bi)狀態下其ACC端是否(fou)有(you)電(dian)(dian)(dian)(dian)壓信號(hao)輸出(chu)（若有(you)則(ze)更換鑰(yao)(yao)(yao)匙(chi)(chi)開(kai)(kai)(kai)關(guan)(guan)(guan)），若鑰(yao)(yao)(yao)匙(chi)(chi)開(kai)(kai)(kai)關(guan)(guan)(guan)之(zhi)間(jian)沒有(you)得到(dao)電(dian)(dian)(dian)(dian)壓輸入輸出(chu)，則(ze)系(xi)統設計電(dian)(dian)(dian)(dian)源(yuan)總開(kai)(kai)(kai)關(guan)(guan)(guan)損壞，更換電(dian)(dian)(dian)(dian)源(yuan)總開(kai)(kai)(kai)關(guan)(guan)(guan)。
