很多人都反映才剛買不久就出(chu)現了一(yi)些問題(ti)？這些問題(ti)是真(zhen)的“有問題(ti)”嗎？下面充電器廠家給大家介紹幾種常識，了解(jie)之(zhi)后(hou)“問題(ti)”就迎刃而解(jie)。

 一(yi)、充電(dian)時電(dian)源(yuan)指示燈亮，充電(dian)指示燈橙色

 首先請檢查一(yi)下(xia)充(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)輸(shu)(shu)出插頭(tou)與電(dian)(dian)(dian)(dian)池(chi)(chi)盒的(de)(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)插頭(tou)有(you)沒(mei)有(you)插緊。如(ru)確定沒(mei)有(you)問題，可(ke)(ke)檢查一(yi)下(xia)電(dian)(dian)(dian)(dian)池(chi)(chi)盒上面的(de)(de)(de)保險絲(si)管(guan)是否(fou)開(kai)路或(huo)保險絲(si)座有(you)松動接(jie)觸不(bu)良現象。另外，有(you)的(de)(de)(de)車(che)型要(yao)把電(dian)(dian)(dian)(dian)池(chi)(chi)鎖打開(kai)后才能充(chong)(chong)電(dian)(dian)(dian)(dian)。如(ru)果以上故(gu)障(zhang)(zhang)均排(pai)除，考慮一(yi)下(xia)充(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)輸(shu)(shu)出線(xian)(xian)(xian)(xian)是否(fou)開(kai)路，可(ke)(ke)用萬用表電(dian)(dian)(dian)(dian)壓(ya)擋(dang)（200V擋(dang)）測量一(yi)下(xia)電(dian)(dian)(dian)(dian)源器(qi)的(de)(de)(de)空載(zai)輸(shu)(shu)出電(dian)(dian)(dian)(dian)壓(ya)，應(ying)為41-44V（配36V電(dian)(dian)(dian)(dian)池(chi)(chi)因充(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)不(bu)同(tong)有(you)所(suo)不(bu)同(tong)），如(ru)沒(mei)有(you)的(de)(de)(de)話，可(ke)(ke)能是充(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)輸(shu)(shu)出線(xian)(xian)(xian)(xian)開(kai)路，并將充(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)打開(kai)，換(huan)(huan)一(yi)根輸(shu)(shu)出線(xian)(xian)(xian)(xian)，即可(ke)(ke)排(pai)除故(gu)障(zhang)(zhang)。注(zhu)意：在(zai)更換(huan)(huan)充(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)輸(shu)(shu)出線(xian)(xian)(xian)(xian)時，一(yi)定要(yao)注(zhu)意原機的(de)(de)(de)正負極不(bu)要(yao)接(jie)反。

 二、電(dian)源指示燈(deng)不亮，充電(dian)指示燈(deng)也不亮

 檢查電(dian)(dian)源適(shi)配器(qi)輸(shu)入電(dian)(dian)源插頭與市電(dian)(dian)有(you)(you)(you)(you)沒(mei)有(you)(you)(you)(you)連接(jie)好，可將充電(dian)(dian)器(qi)輸(shu)入插頭插至正常(chang)的(de)電(dian)(dian)源插座中(zhong)試一(yi)下(xia)，如(ru)情(qing)況(kuang)依(yi)舊，將充電(dian)(dian)器(qi)外殼(ke)打開，觀(guan)察一(yi)下(xia)機內保險絲(si)有(you)(you)(you)(you)沒(mei)有(you)(you)(you)(you)斷(duan)，如(ru)沒(mei)有(you)(you)(you)(you)斷(duan)，先檢查一(yi)下(xia)電(dian)(dian)源輸(shu)入線(xian)(xian)是(shi)否(fou)良好，在(zai)排除(chu)電(dian)(dian)源輸(shu)入線(xian)(xian)的(de)故障后，應(ying)檢查一(yi)下(xia)電(dian)(dian)路板上高壓(ya)區附近(jin)的(de)元(yuan)器(qi)件(jian)是(shi)否(fou)有(you)(you)(you)(you)虛焊，保險絲(si)座是(shi)否(fou)有(you)(you)(you)(you)接(jie)觸不良現象(xiang)，重(zhong)點檢查變壓(ya)器(qi)T1、三極管V1、V2等是(shi)否(fou)有(you)(you)(you)(you)虛焊現象(xiang)。另外，R5或R6開路，也會引起上述故障，如(ru)機內保險絲(si)已斷(duan)，則千(qian)萬不要更(geng)換大安培的(de)保險絲(si)管（充電(dian)(dian)器(qi)的(de)保險絲(si)管一(yi)般(ban)為(wei)2A），應(ying)重(zhong)點檢查D1-D4、V1、V2、R4、R7及D15、D21 有(you)(you)(you)(you)無損(sun)壞(huai)(huai)，如(ru)有(you)(you)(you)(you)損(sun)壞(huai)(huai)，可用同(tong)類型的(de)更(geng)換。請注意，上述元(yuan)件(jian)損(sun)壞(huai)(huai)時(shi)，可能會同(tong)時(shi)損(sun)壞(huai)(huai)一(yi)到二個(ge)，有(you)(you)(you)(you)時(shi)可能會同(tong)時(shi)損(sun)壞(huai)(huai)好幾(ji)個(ge)，檢修時(shi)需要逐一(yi)檢查、更(geng)換這些元(yuan)件(jian)后才能通電(dian)(dian)。

 三、嚴重發熱，甚(shen)至(zhi)有外殼燒(shao)化變形現象

 這主要(yao)是(shi)(shi)部分用(yong)戶經常(chang)隨車攜帶(dai)造(zao)成(cheng)部分元器件松動(dong)引起的故障(zhang)。主要(yao)表現(xian)為：C18松動(dong)虛焊時(shi)，會(hui)造(zao)成(cheng)V1、V2工作狀態不(bu)正常(chang)，熱量(liang)很大(da)，嚴重時(shi)充(chong)電器外殼變形，電路板(ban)燒焦(jiao)，導(dao)致(zhi)V1、V2損壞(huai)，可將C18重新焊接好(hao)，檢查V1、V2、R4、R7。如仍不(bu)能(neng)排除故障(zhang)，則(ze)需(xu)檢查D15、D21中(zhong)是(shi)(shi)否有(you)一(yi)只開路，另(ling)外，有(you)些(xie)廠家(jia)的輸出(chu)整流(liu)管采用(yong)一(yi)只雙二極管，其中(zhong)一(yi)只開路亦造(zao)成(cheng)上述故障(zhang)，有(you)時(shi)該故障(zhang)會(hui)造(zao)成(cheng) V1、V2中(zhong)一(yi)只損壞(huai)。需(xu)同時(shi)檢查及更換(huan)。

 四、發熱(re)量大且伴(ban)有異常響聲(sheng)

 故(gu)障原因是輸出(chu)級消振(zhen)阻容R31、C17損壞所致。另外，C12開路或虛焊也會引起上述故(gu)障。

 五、工作時有異(yi)常響聲(sheng)，充不進電

 檢查電路板上C8是否有虛焊或損壞，一般(ban)更換(huan)C8均(jun)能解決。

 六、工(gong)作時有異(yi)常響(xiang)聲，電(dian)(dian)源(yuan)指示(shi)燈與充電(dian)(dian)指示(shi)燈暗且閃爍

 故(gu)障原(yuan)因是(shi)IC1損(sun)壞，更(geng)換(huan)時務必小心，不要將印制板銅箔損(sun)壞，更(geng)換(huan)正常(chang)后(hou)，需調整R28使(shi)電源適(shi)配(pei)器輸(shu)出電壓在正常(chang)工(gong)作范圍內。
