    I recently rescued a 1999 1200 that has tach that does not indicate. The speedometer and odometer did not work until I replaced the vss. What tests should I do to troubleshoot my tach?

    My Tach sits 10 up from 0 even when turned Off..Thats with the ignition turned Off. What can the trouble be? I turn key on then off then it sits on 0.

    How does it read with ignition ON? I have seem some tachs that do that but are accurate when running.
