收到江同學寄來的FZR轉速表,發現過電後好像轉速表有時會抖一下
有時又完全不會動
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1510931000_2.jpg]()
因為光線好像怪怪的,發現損壞的燈炮
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1510931001_3.jpg]()
拔下,過電後確實不會亮
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1510931001_4.jpg]()
換顆新的
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1510931002_5.jpg]()
反過來看看,中間的也沒亮
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1510931002_6.jpg]()
換新的
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1510931003_7.jpg]()
全都會亮了
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1510931004_8.jpg]()
接下來弄轉速表
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1510931004_9.jpg]()
機板看來還不錯
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1510931005_10.jpg]()
表頭一解開,發現表頭的線斷掉了
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1510931006_11.jpg]()
掉了
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1510931006_12.jpg]()

![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1510931007_13.jpg]()
把斷線的線重新播好一小段露出來,量起來表頭好像沒壞
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1510931007_14.jpg]()
播好線頭的照片
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1510931008_15.jpg]()
重新接回機板看看
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1510931009_16.jpg]()

![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1510931009_17.jpg]()
反正就重作吧,表頭拆下
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1510931010_18.jpg]()

這板子還真是我第一次看過印刷印的最漂亮的機板
焊上IC座
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1510931012_22.jpg]()
一下就焊完了
