(1)檢(jian)查垃圾車閃光繼電器火線頭是(shi)否有電。若(ruo)無電，應檢(jian)查該線至(zhi)電源(yuan)間是(shi)否斷路。

(2)若(ruo)(ruo)(ruo)垃圾(ji)車有電(dian)(dian)時(shi)(shi)，用(yong)螺絲(si)刀將閃(shan)光繼(ji)電(dian)(dian)器(qi)兩接(jie)線柱連接(jie)．這時(shi)(shi)轉(zhuan)向(xiang)燈(deng)(deng)(deng)亮(liang)，說明閃(shan)光繼(ji)電(dian)(dian)器(qi)有故障，應更換(huan)。若(ruo)(ruo)(ruo)不亮(liang)，應檢查閃(shan)光繼(ji)電(dian)(dian)器(qi)。打開閃(shan)光繼(ji)電(dian)(dian)器(qi)蓋、檢查線圈、電(dian)(dian)阻(zu)是否完好。若(ruo)(ruo)(ruo)電(dian)(dian)阻(zu)發熱，而觸點(dian)又不能閉(bi)合(he)時(shi)(shi)，可按下活動(dong)觸點(dian)；此時(shi)(shi)若(ruo)(ruo)(ruo)轉(zhuan)向(xiang)燈(deng)(deng)(deng)亮(liang)，表明繼(ji)電(dian)(dian)器(qi)有故障。觸點(dian)間隙(xi)過(guo)大(da)時(shi)(shi)應進(jin)行調整。若(ruo)(ruo)(ruo)按下活動(dong)觸點(dian)使觸點(dian)閉(bi)合(he)時(shi)(shi)轉(zhuan)向(xiang)燈(deng)(deng)(deng)仍(reng)不亮(liang)，可用(yong)螺絲(si)刀將觸點(dian)短接(jie)，此時(shi)(shi)若(ruo)(ruo)(ruo)燈(deng)(deng)(deng)亮(liang)，則說明觸點(dian)氧化。

(3)用(yong)螺絲(si)刀將垃圾車(che)閃光(guang)繼電器兩(liang)接(jie)線(xian)(xian)柱短(duan)接(jie)時(shi)(shi)，轉(zhuan)(zhuan)向燈(deng)不亮，則(ze)可能是轉(zhuan)(zhuan)向開關有故(gu)障(zhang)。檢(jian)查時(shi)(shi)，可用(yong)螺絲(si)刀分別接(jie)通(tong)轉(zhuan)(zhuan)向開關火線(xian)(xian)與左、右燈(deng)線(xian)(xian)接(jie)線(xian)(xian)性。若燈(deng)亮．表示轉(zhuan)(zhuan)向開關有故(gu)障(zhang)，應(ying)拆下檢(jian)修或更換。
