I'd throw it out and get a different one.  Just so you know, a 1985 to 1992
Golf and Jetta tach will drop right in the plastic casing.  You do need to
take the Jetta face plate with you and it will be a slightly different font,
but they do work quite well.  We use these for people who are doing an I4
swap and need a higher revving tach or a Diesel tach.

Subject: Tach schematics/repair hints?

Hello Volks -- couple days ago my tach turned up its toes -- any time power
is applied it runs up to just below the mechanical stop (well offscale) and
hangs there.  Anyone with schematics and/or practical troubleshooting
experience with these?  I haven't pulled the cluster yet, though I did get
a reminder that the primary coil pulse is available at a terminal on the
back of the tach...ouch <g>

Thanks,
david
