電瓶是加水式的統力7號,換新後不到一年
因為中間有陣子比較少騎,啟動馬達就開始愈來愈打不動
本來以為是電瓶水乾掉,但拆開發現水位在標準範圍內
於是拿了電表來量看看電壓
一、發動前電瓶電壓約12.2V,發動後約14V
轉速拉到3000rpm-->電壓掉到13.8V
二、後來換了顆新的整流器測試,發動後上升到14.2V
轉速拉到3000rpm-->電壓掉到14V
三、依照原廠維修手冊,轉速拉到3000rpm之回充電壓應為14.3~15.3V
依照上面三點,個人的猜測:
1.發動前電瓶電壓還有12.2V →原電瓶應該還可以
2.換新整流器,3000rpm下的回充電壓上升0.2V →原整流器可能老化
3.既然電瓶還可以,整流器也換新了,
回充電壓仍低於原廠最低值,是否可能是電盤的問題?
以上的個人推論是否正確? 感謝大家!
