YG－WY H型電動互輪車智能充電器有電壓輸出，但充不進去電。

　　根據故障現象，初步判斷電源輸人整流電路部分有故障，有可能是輸出電源插頭與充電插座接觸不良所致。用十字旋具將充電器的(de)4顆緊固螺釘拆下，打開(kai)上(shang)蓋。首(shou)先看到輸(shu)(shu)八整流電(dian)(dian)(dian)(dian)路(lu)申(shen)的(de)咆源(yuan)(yuan)濾波電(dian)(dian)(dian)(dian)容(rong)C5（82 uF/400V）已(yi)炸裂(lie)、漏(lou)液。然后用(yong)萬(wan)用(yong)表：“R*1”擋測量輸(shu)(shu)出(chu)電(dian)(dian)(dian)(dian)源(yuan)(yuan)插(cha)頭(tou)(tou)(tou)和充電(dian)(dian)(dian)(dian)插(cha)座，發現阻(zu)值(zhi)很小，幾乎(hu)為0Ω，這說(shuo)明它(ta)們(men)接觸良(liang)好。為了萬(wan)無一失，再用(yong)萬(wan)用(yong)表測量其他(ta)易損壞的(de)元件及充電(dian)(dian)(dian)(dian)保(bao)險管(guan)，相關的(de)電(dian)(dian)(dian)(dian)路(lu)圖(tu)如(ru)圖(tu)1 所(suo)示。經(jing)測量均未(wei)損壞。最后換(huan)上(shang)一個與(yu)原(yuan)來(lai)的(de)耐(nai)壓（耐(nai)壓可大于原(yuan)來(lai)的(de)值(zhi)，但(dan)絕對不能小于原(yuan)來(lai)的(de)值(zhi)）和容(rong)量相同的(de)電(dian)(dian)(dian)(dian)解(jie)電(dian)(dian)(dian)(dian)容(rong)（82 n F／400∨），焊(han)好，插(cha)上(shang)電(dian)(dian)(dian)(dian)源(yuan)(yuan)插(cha)頭(tou)(tou)(tou)和充電(dian)(dian)(dian)(dian)插(cha)頭(tou)(tou)(tou)，經(jing)數小時的(de)充電(dian)(dian)(dian)(dian)，充龜器上(shang)的(de)“充滿”指(zhi)示燈亮(liang)，表明蓄電(dian)(dian)(dian)(dian)池已(yi)充滿，故障排(pai)除。
