一、充(chong)電(dian)時電(dian)源指(zhi)示燈亮，充(chong)電(dian)指(zhi)示燈橙色

      首先請檢查一下充電器輸出插頭與電池盒的充電插頭有沒有插緊。如確定沒有問題，可檢查一下電池盒上面的保險絲管是否開路或保險絲座有松動接觸不良現象。另外，有的車型要把電池鎖打開后才能充電。如果以上故障均排除，考慮一下充電器輸(shu)出線是否開(kai)路，可用(yong)萬用(yong)表(biao)電(dian)(dian)(dian)(dian)(dian)壓擋(dang)（200V擋(dang)）測量一下充電(dian)(dian)(dian)(dian)(dian)器(qi)的空載輸(shu)出電(dian)(dian)(dian)(dian)(dian)壓，應為41-44V（配36V電(dian)(dian)(dian)(dian)(dian)池因充電(dian)(dian)(dian)(dian)(dian)器(qi)不(bu)同有所不(bu)同），如沒(mei)有的話，可能是充電(dian)(dian)(dian)(dian)(dian)器(qi)輸(shu)出線開(kai)路，并將充電(dian)(dian)(dian)(dian)(dian)器(qi)打開(kai)，換(huan)一根輸(shu)出線，即可排除故(gu)障。注意(yi)：在更換(huan)充電(dian)(dian)(dian)(dian)(dian)器(qi)輸(shu)出線時(shi)，一定要注意(yi)原機的正(zheng)負極不(bu)要接反。

二(er)、電源指示(shi)燈(deng)不(bu)亮(liang)(liang)，充(chong)電指示(shi)燈(deng)也不(bu)亮(liang)(liang)

檢(jian)(jian)查(cha)充電(dian)(dian)(dian)(dian)(dian)器(qi)輸(shu)入(ru)電(dian)(dian)(dian)(dian)(dian)源(yuan)插頭與市電(dian)(dian)(dian)(dian)(dian)有(you)沒有(you)連接好，可(ke)將充電(dian)(dian)(dian)(dian)(dian)器(qi)輸(shu)入(ru)插頭插至(zhi)正(zheng)常的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)插座中(zhong)試(shi)一(yi)下，如情(qing)況依舊，將充電(dian)(dian)(dian)(dian)(dian)器(qi)外(wai)殼打開(kai)，觀察一(yi)下機內保(bao)險(xian)(xian)絲有(you)沒有(you)斷(duan)，如沒有(you)斷(duan)，先(xian)檢(jian)(jian)查(cha)一(yi)下電(dian)(dian)(dian)(dian)(dian)源(yuan)輸(shu)入(ru)線(xian)是否(fou)良(liang)好，在排除電(dian)(dian)(dian)(dian)(dian)源(yuan)輸(shu)入(ru)線(xian)的(de)(de)(de)故(gu)障(zhang)后，應(ying)檢(jian)(jian)查(cha)一(yi)下電(dian)(dian)(dian)(dian)(dian)路板上高壓(ya)區(qu)附近的(de)(de)(de)元(yuan)器(qi)件是否(fou)有(you)虛(xu)焊，保(bao)險(xian)(xian)絲座是否(fou)有(you)接觸不(bu)良(liang)現象，重(zhong)點檢(jian)(jian)查(cha)變壓(ya)器(qi)T1、三極管(guan)V1、V2等是否(fou)有(you)虛(xu)焊現象。另外(wai)，R5或R6開(kai)路，也會引(yin)起上述故(gu)障(zhang)，如機內保(bao)險(xian)(xian)絲已斷(duan)，則千萬(wan)不(bu)要更換大安培的(de)(de)(de)保(bao)險(xian)(xian)絲管(guan)（充電(dian)(dian)(dian)(dian)(dian)器(qi)的(de)(de)(de)保(bao)險(xian)(xian)絲管(guan)一(yi)般(ban)為2A），應(ying)重(zhong)點檢(jian)(jian)查(cha)D1-D4、V1、V2、R4、R7及(ji)D15、D21 有(you)無損壞(huai)，如有(you)損壞(huai)，可(ke)用同類型的(de)(de)(de)更換。請注意，上述元(yuan)件損壞(huai)時(shi)(shi)(shi)，可(ke)能會同時(shi)(shi)(shi)損壞(huai)一(yi)到(dao)二個，有(you)時(shi)(shi)(shi)可(ke)能會同時(shi)(shi)(shi)損壞(huai)好幾個，檢(jian)(jian)修時(shi)(shi)(shi)需要逐一(yi)檢(jian)(jian)查(cha)、更換這些元(yuan)件后才(cai)能通電(dian)(dian)(dian)(dian)(dian)。

三、嚴(yan)重發熱，甚(shen)至有外殼燒化變形現(xian)象(xiang)

這主要是(shi)部分用戶經常隨(sui)車攜帶造成(cheng)部分元器(qi)件松(song)動引起的(de)故(gu)障(zhang)。主要表現為(wei)：C18松(song)動虛焊時(shi)(shi)，會(hui)(hui)造成(cheng)V1、V2工(gong)作狀態不(bu)正常，熱量很大，嚴重時(shi)(shi)充電器(qi)外(wai)殼(ke)變形，電路(lu)板燒焦，導(dao)致(zhi)V1、V2損壞(huai)，可將C18重新焊接好，檢(jian)查V1、V2、R4、R7。如仍不(bu)能排(pai)除(chu)故(gu)障(zhang)，則需檢(jian)查D15、D21中是(shi)否有一(yi)只開路(lu)，另外(wai)，有些(xie)廠家的(de)輸出整流(liu)管(guan)采用一(yi)只雙二極管(guan)，其(qi)中一(yi)只開路(lu)亦造成(cheng)上述故(gu)障(zhang)，有時(shi)(shi)該(gai)故(gu)障(zhang)會(hui)(hui)造成(cheng) V1、V2中一(yi)只損壞(huai)。需同(tong)時(shi)(shi)檢(jian)查及更換。

四(si)、發熱(re)量大且伴有異(yi)常響聲

故(gu)障原(yuan)因是輸出(chu)級消振阻容R31、C17損壞所致。另外，C12開(kai)路或(huo)虛焊(han)也(ye)會引起上(shang)述故(gu)障。

五、工作時(shi)有異常響聲，充不進電

檢查電路板(ban)上C8是否有虛(xu)焊或(huo)損壞，一般更換(huan)C8均能解(jie)決。

六、工作時有異常響聲，電(dian)源指(zhi)示(shi)燈與充(chong)電(dian)指(zhi)示(shi)燈暗且閃爍

故障原因是IC1損(sun)壞(huai)，更換時務必小(xiao)心，不要將(jiang)印制(zhi)板銅箔(bo)損(sun)壞(huai)，更換正(zheng)常后，需調整R28使充電器輸出電壓在正(zheng)常工作范圍內。

七、輸出電壓很高

輸出電壓很高(gao)（大于50V），其故障原因是C15短路(lu)或R26開(kai)路(lu)，具體(ti)判斷時可測量(liang)IC1集(ji)成電路(lu)的“1”腳電壓。

注(zhu)：更(geng)換R26后，應(ying)重(zhong)新調整R28使充電(dian)器輸(shu)出電(dian)壓保持(chi)正常。

八、輸出(chu)電壓(ya)正(zheng)常，但充電電流很小

檢查R30、R11、R13是否接觸(chu)不良或損壞，如(ru)正(zheng)常請更換IC1即可排除故障。

九、輸(shu)出電壓(ya)正常(chang)，充電指(zhi)示燈無(wu)指(zhi)示或指(zhi)示不(bu)正確

通常是(shi)由(you)于IC2損壞(huai)或LED2損壞(huai)，可更(geng)換(huan)。

十、輸出部分銅箔(bo)燒(shao)斷

打開充電器后發現充電器輸出部分銅箔燒斷，這通常是將電池正負極反接的結果，由此而引起的故障將會導致充電器許多元件損壞。如果充電器保險絲沒有壞，則通常更換R30、IC1、IC2后將斷銅箔連上即可恢復正常。如果充電器的保(bao)險絲(si)已斷，則故障較嚴重D1-D4、 V1-V2、R4、R7等(deng)均有可能損壞，需測量后(hou)逐一(yi)更換。
