Testing overload protection relay

Hi, I have a 1986 190d 2.5 non-turbo.

My tach only works when it wants to, about 25% of the time.

I tested the sensor on the bell housing and it tests good.

Is there any way to test the overload protection relay?

I understand that it sends a signal to the tach.
