2018-03-03 收到顏同學寄來的FZR儀表,說轉速表壞了

過電後都不會動,表燈也都怪怪的,只有右上三顆正常會亮
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1520668418.jpg]()
翻過來先弄燈炮
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1520668424.jpg]()
拔出四顆,居然全都不亮…也太神奇
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1520668430.jpg]()
燈炮全都換掉,一切都正常了
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1520668435.jpg]()
右下角這個小燈,有點接觸不良,推出來磨一下
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1520668441.jpg]()
用電動工具打磨
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1520668447.jpg]()
OK,都會亮了
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1520668453.jpg]()
燈炮插回,儀表看的到光線了

拆轉速表,順便把PIN打磨除銹

機板的狀況看起來好像沒燒東西

另一個角度

表頭解下,再量一次,還是不會轉
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1520668494.jpg]()
看不出來哪壞的零件

透明壓克力的狀況,油表的怎會龜裂成這樣XD
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1520668562.jpg]()
擦一擦,透明不少,不過還是有很多龜裂,只能這樣了
![//59.126.75.42/photo/small.php?w_size=1280&compassion=95&file_name=users/shadow/1520668568.jpg]()
