YG－WY H型電動互輪車智能充電器有(you)電壓輸出，但充不進(jin)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4顆緊(jin)固螺釘拆下，打(da)開(kai)上(shang)(shang)(shang)蓋。首先(xian)看到輸(shu)八整流(liu)電(dian)(dian)路(lu)申的咆源(yuan)濾(lv)波電(dian)(dian)容(rong)C5（82 uF/400V）已炸裂、漏液。然后用(yong)萬(wan)(wan)用(yong)表：“R*1”擋測量輸(shu)出電(dian)(dian)源(yuan)插(cha)頭和充(chong)電(dian)(dian)插(cha)座，發現(xian)阻值(zhi)很(hen)小，幾乎為0Ω，這說明它們接觸良(liang)好。為了萬(wan)(wan)無一失，再用(yong)萬(wan)(wan)用(yong)表測量其他易(yi)損(sun)壞的元件(jian)及充(chong)電(dian)(dian)保險管，相關(guan)的電(dian)(dian)路(lu)圖如(ru)圖1 所示。經測量均未損(sun)壞。最(zui)后換上(shang)(shang)(shang)一個與(yu)原來的耐(nai)壓(ya)(ya)（耐(nai)壓(ya)(ya)可大于原來的值(zhi)，但絕對不能小于原來的值(zhi)）和容(rong)量相同的電(dian)(dian)解電(dian)(dian)容(rong)（82 n F／400∨），焊好，插(cha)上(shang)(shang)(shang)電(dian)(dian)源(yuan)插(cha)頭和充(chong)電(dian)(dian)插(cha)頭，經數小時的充(chong)電(dian)(dian)，充(chong)龜器上(shang)(shang)(shang)的“充(chong)滿(man)”指示燈亮，表明蓄電(dian)(dian)池已充(chong)滿(man)，故障(zhang)排除(chu)。
