車友林Sir把轉速表寄來請我檢查,然後里程表要修歸零鈕
上次修這組表似乎快一年前了
2016-04-16FZ2轉速表(郭xx)
雖然跟林先生不知道啥關係,不過最近在用時,車主說會晃,就再作一次看看
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1496852009_2.jpg]()
拆解表燈,這組是用白鐵螺絲,後來有車友表示白鐵螺絲不太好用
那我就統一換回銅的好了
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1496852009_3.jpg]()
拆表,照原本黏合的地上切開
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1496852009_4.jpg]()
表拆下,以前作過燈柱的地方,真有趣
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1496852009_5.jpg]()
量看看
看起來好像沒啥問題,但轉速有飆高的狀況
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1496852009_6.jpg]()
板子的東西看起來也都正常,不知道哪壞了
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1496852009_7.jpg]()
高一點的角度
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1496852009_8.jpg]()
電容看起來也都正常
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1496852009_9.jpg]()
反正要重作了,表頭拆下
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1496852009_10.jpg]()
解焊
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1496852009_11.jpg]()
解焊完了
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1496852009_12.jpg]()
不知道是不是上面那顆R1的電阻在搞鬼,輕輕一拉,電組的心斷了
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1496852009_13.jpg]()
全部拆掉換新
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1496852009_14.jpg]()
焊上新零件
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1496852009_15.jpg]()
焊完90%
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1496852009_16.jpg]()
好了,表頭裝上
重新校正確認
我發現在0~2000轉他是忽然跳上去,經確認後,在軸心好像稍微黏黏的,用手推一推似乎就正常了
不過影片沒有重新再錄
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1496852009_17.jpg]()
裝回
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1496852009_18.jpg]()
背板
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1496852009_19.jpg]()
背板零件裝上
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1496852009_20.jpg]()
14000,這次校準一點看看
轉速表應該OK了
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1496852009_21.jpg]()
然後里程表的部分
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1496852009_22.jpg]()
畫線
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1496852009_23.jpg]()
準備切
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1496852009_24.jpg]()
切好了
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1496852009_25.jpg]()
原來橡皮在裡面,還以為弄丟了
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1496852009_26.jpg]()
整理粉屑
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1496852009_27.jpg]()
裝箱,拿到一樓用空壓機噴
太晚了,不好意思開空壓機,待續…
然後我發現家裡的歸零鈕也用完了,明天再去補貨
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1497016398_9.jpg]()
台中電子街找了二間,原本有賣的居然沒貨了,沒貨是指沒黑色的
找好久才找到幾個,以後不知道怎修歸零鈕,哈哈哈
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1497016398_11.jpg]()
這次要修的歸零鈕…斷的好徹底,這樣不知道焊不焊的住耶@_@
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1497016398_12.jpg]()
剩不到1mm,到底怎麼折斷的啊
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1497016398_13.jpg]()
焊上空心鋁桿,要沾不少焊油,不然焊不太住
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1497016398_14.jpg]()
焊上旋鈕,可以轉了!
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1497016398_15.jpg]()
背板上白鐵螺絲
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1497016398_16.jpg]()
黏合
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1497016398_18.jpg]()
上膠帶
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1497016398_19.jpg]()
然後把外蓋黏上
測試,運作良好
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1497016398_20.jpg]()
完工嘍
