很多人都反(fan)映才剛買不久就出現了一些問(wen)題(ti)？這些問(wen)題(ti)是真的“有問(wen)題(ti)”嗎？下(xia)面充電器廠(chang)家給大家介(jie)紹幾種常識，了解(jie)之后“問(wen)題(ti)”就迎刃而解(jie)。

 一、充電時電源指示燈亮，充電指示燈橙色

 首先(xian)請(qing)檢(jian)查一(yi)下充(chong)(chong)(chong)電(dian)(dian)器輸(shu)(shu)出(chu)(chu)插頭與(yu)電(dian)(dian)池(chi)盒(he)的(de)(de)充(chong)(chong)(chong)電(dian)(dian)插頭有(you)(you)(you)沒(mei)有(you)(you)(you)插緊(jin)。如(ru)確定(ding)(ding)沒(mei)有(you)(you)(you)問題，可檢(jian)查一(yi)下電(dian)(dian)池(chi)盒(he)上(shang)(shang)面的(de)(de)保(bao)險(xian)絲(si)管是(shi)(shi)否開(kai)(kai)(kai)路(lu)或保(bao)險(xian)絲(si)座有(you)(you)(you)松動接(jie)觸不良(liang)現象。另外，有(you)(you)(you)的(de)(de)車型要(yao)(yao)(yao)把電(dian)(dian)池(chi)鎖打開(kai)(kai)(kai)后才能(neng)充(chong)(chong)(chong)電(dian)(dian)。如(ru)果以上(shang)(shang)故障均(jun)排除，考慮一(yi)下充(chong)(chong)(chong)電(dian)(dian)器輸(shu)(shu)出(chu)(chu)線(xian)(xian)是(shi)(shi)否開(kai)(kai)(kai)路(lu)，可用(yong)萬用(yong)表(biao)電(dian)(dian)壓擋（200V擋）測量一(yi)下電(dian)(dian)源器的(de)(de)空(kong)載輸(shu)(shu)出(chu)(chu)電(dian)(dian)壓，應為41-44V（配36V電(dian)(dian)池(chi)因充(chong)(chong)(chong)電(dian)(dian)器不同有(you)(you)(you)所(suo)不同），如(ru)沒(mei)有(you)(you)(you)的(de)(de)話，可能(neng)是(shi)(shi)充(chong)(chong)(chong)電(dian)(dian)器輸(shu)(shu)出(chu)(chu)線(xian)(xian)開(kai)(kai)(kai)路(lu)，并將充(chong)(chong)(chong)電(dian)(dian)器打開(kai)(kai)(kai)，換一(yi)根輸(shu)(shu)出(chu)(chu)線(xian)(xian)，即可排除故障。注意(yi)：在更換充(chong)(chong)(chong)電(dian)(dian)器輸(shu)(shu)出(chu)(chu)線(xian)(xian)時，一(yi)定(ding)(ding)要(yao)(yao)(yao)注意(yi)原機的(de)(de)正負極不要(yao)(yao)(yao)接(jie)反。

 二、電(dian)(dian)源(yuan)指示燈(deng)不(bu)亮，充電(dian)(dian)指示燈(deng)也不(bu)亮

 檢(jian)(jian)查(cha)(cha)(cha)電(dian)(dian)(dian)源(yuan)適配器輸(shu)入(ru)電(dian)(dian)(dian)源(yuan)插頭與市(shi)電(dian)(dian)(dian)有(you)沒(mei)有(you)連接好(hao)(hao)，可(ke)(ke)將充電(dian)(dian)(dian)器輸(shu)入(ru)插頭插至(zhi)正(zheng)常的電(dian)(dian)(dian)源(yuan)插座中試(shi)一(yi)(yi)(yi)下，如(ru)情況依舊(jiu)，將充電(dian)(dian)(dian)器外殼打開，觀(guan)察一(yi)(yi)(yi)下機內保(bao)險絲(si)有(you)沒(mei)有(you)斷(duan)(duan)，如(ru)沒(mei)有(you)斷(duan)(duan)，先檢(jian)(jian)查(cha)(cha)(cha)一(yi)(yi)(yi)下電(dian)(dian)(dian)源(yuan)輸(shu)入(ru)線是否良(liang)好(hao)(hao)，在排除電(dian)(dian)(dian)源(yuan)輸(shu)入(ru)線的故障后，應檢(jian)(jian)查(cha)(cha)(cha)一(yi)(yi)(yi)下電(dian)(dian)(dian)路板上高壓區附近的元(yuan)器件(jian)是否有(you)虛焊，保(bao)險絲(si)座是否有(you)接觸(chu)不良(liang)現(xian)(xian)象，重(zhong)點檢(jian)(jian)查(cha)(cha)(cha)變壓器T1、三極管V1、V2等(deng)是否有(you)虛焊現(xian)(xian)象。另外，R5或(huo)R6開路，也(ye)會(hui)引起上述故障，如(ru)機內保(bao)險絲(si)已斷(duan)(duan)，則(ze)千萬(wan)不要更換(huan)大安(an)培的保(bao)險絲(si)管（充電(dian)(dian)(dian)器的保(bao)險絲(si)管一(yi)(yi)(yi)般(ban)為2A），應重(zhong)點檢(jian)(jian)查(cha)(cha)(cha)D1-D4、V1、V2、R4、R7及D15、D21 有(you)無損(sun)(sun)壞(huai)，如(ru)有(you)損(sun)(sun)壞(huai)，可(ke)(ke)用(yong)同(tong)類(lei)型的更換(huan)。請注(zhu)意，上述元(yuan)件(jian)損(sun)(sun)壞(huai)時(shi)(shi)(shi)，可(ke)(ke)能(neng)(neng)會(hui)同(tong)時(shi)(shi)(shi)損(sun)(sun)壞(huai)一(yi)(yi)(yi)到二(er)個(ge)，有(you)時(shi)(shi)(shi)可(ke)(ke)能(neng)(neng)會(hui)同(tong)時(shi)(shi)(shi)損(sun)(sun)壞(huai)好(hao)(hao)幾個(ge)，檢(jian)(jian)修(xiu)時(shi)(shi)(shi)需要逐一(yi)(yi)(yi)檢(jian)(jian)查(cha)(cha)(cha)、更換(huan)這些元(yuan)件(jian)后才(cai)能(neng)(neng)通電(dian)(dian)(dian)。

 三、嚴重發熱(re)，甚至有外殼燒(shao)化(hua)變(bian)形現象

 這主要是(shi)部(bu)分用戶(hu)經常隨車(che)攜(xie)帶(dai)造(zao)成部(bu)分元器件松(song)動引(yin)起的故(gu)(gu)障(zhang)。主要表現(xian)為：C18松(song)動虛焊時，會(hui)造(zao)成V1、V2工作狀(zhuang)態(tai)不正常，熱量很大，嚴重(zhong)(zhong)時充電器外殼變(bian)形(xing)，電路(lu)(lu)板燒(shao)焦(jiao)，導致V1、V2損(sun)壞，可將C18重(zhong)(zhong)新焊接好，檢(jian)(jian)查(cha)(cha)V1、V2、R4、R7。如仍不能排除故(gu)(gu)障(zhang)，則需檢(jian)(jian)查(cha)(cha)D15、D21中(zhong)是(shi)否有一(yi)只開路(lu)(lu)，另外，有些廠(chang)家的輸(shu)出(chu)整流(liu)管(guan)采用一(yi)只雙二極管(guan)，其中(zhong)一(yi)只開路(lu)(lu)亦造(zao)成上述故(gu)(gu)障(zhang)，有時該故(gu)(gu)障(zhang)會(hui)造(zao)成 V1、V2中(zhong)一(yi)只損(sun)壞。需同時檢(jian)(jian)查(cha)(cha)及(ji)更換。

 四、發(fa)熱量(liang)大且伴(ban)有異常響(xiang)聲(sheng)

 故(gu)障原因(yin)是(shi)輸出級消振阻容(rong)R31、C17損壞(huai)所致。另(ling)外，C12開路或虛焊(han)也會引(yin)起上述(shu)故(gu)障。

 五、工作(zuo)時有異常響聲，充(chong)不(bu)進電

 檢查電路板上(shang)C8是(shi)否有虛焊或損壞，一般(ban)更(geng)換(huan)C8均能解決。

 六、工作時有異常響聲，電源指示(shi)燈(deng)與充電指示(shi)燈(deng)暗(an)且閃爍

 故(gu)障原因是IC1損(sun)(sun)壞，更換時務必小心，不要將印(yin)制板銅箔損(sun)(sun)壞，更換正常后，需調整(zheng)R28使電(dian)源適配器(qi)輸(shu)出電(dian)壓在正常工(gong)作范圍內(nei)。
