Check the OVP and see if the fuse came loose (again). Maybe time for a replacement, the fuse clips may have lost their spring temper and that is why the fuse falls out. Both the EDS (which drives the tach) and the ABS come off the OVP relay.

The wiper was from a JY 1990 ish 300E, maybe it’s going south. Can’t remember if I put the original in the back when I sold the car to you along with all the other parts I had accumulated.
