Jay_bob's wagon odd electrical issues
The tach drop to zero and the abs light comes on at the same time.
Also, the windshield wiper pauses ... I'm guessing that is the gearbox...

Tach and ABS are probably OVP issues. Not sure if the wiper is fed off that circuit or not.

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.
