YG－WY H型電動互輪車智能充電器有電壓(ya)輸(shu)出，但充不(bu)進去(qu)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)(de)(de)4顆緊固螺(luo)釘拆下，打開上(shang)蓋。首先看到輸八整流電(dian)(dian)(dian)(dian)路申(shen)的(de)(de)(de)咆(pao)源濾波電(dian)(dian)(dian)(dian)容C5（82 uF/400V）已炸裂(lie)、漏液。然后用(yong)(yong)萬(wan)用(yong)(yong)表(biao)(biao)：“R*1”擋測(ce)量(liang)(liang)輸出電(dian)(dian)(dian)(dian)源插(cha)(cha)頭(tou)(tou)和(he)(he)充電(dian)(dian)(dian)(dian)插(cha)(cha)座，發現阻值(zhi)(zhi)很小(xiao)，幾乎為0Ω，這說明它們接觸良好。為了萬(wan)無一失，再用(yong)(yong)萬(wan)用(yong)(yong)表(biao)(biao)測(ce)量(liang)(liang)其他易損(sun)壞(huai)的(de)(de)(de)元件及充電(dian)(dian)(dian)(dian)保(bao)險管，相關的(de)(de)(de)電(dian)(dian)(dian)(dian)路圖(tu)如(ru)圖(tu)1 所(suo)示(shi)。經測(ce)量(liang)(liang)均未損(sun)壞(huai)。最(zui)后換上(shang)一個與原(yuan)(yuan)來(lai)的(de)(de)(de)耐(nai)壓(ya)（耐(nai)壓(ya)可(ke)大于原(yuan)(yuan)來(lai)的(de)(de)(de)值(zhi)(zhi)，但(dan)絕對(dui)不能小(xiao)于原(yuan)(yuan)來(lai)的(de)(de)(de)值(zhi)(zhi)）和(he)(he)容量(liang)(liang)相同的(de)(de)(de)電(dian)(dian)(dian)(dian)解(jie)電(dian)(dian)(dian)(dian)容（82 n F／400∨），焊好，插(cha)(cha)上(shang)電(dian)(dian)(dian)(dian)源插(cha)(cha)頭(tou)(tou)和(he)(he)充電(dian)(dian)(dian)(dian)插(cha)(cha)頭(tou)(tou)，經數小(xiao)時的(de)(de)(de)充電(dian)(dian)(dian)(dian)，充龜器上(shang)的(de)(de)(de)“充滿(man)”指示(shi)燈亮，表(biao)(biao)明蓄電(dian)(dian)(dian)(dian)池已充滿(man)，故障排除。
