Although the wiring diagram showed a negative earth system, being a 1965 model, it’s not a positive earth system by any chance? In which case, the diode would be reversed! Double check battery connections to see which pole is connected to earth.
If thats the case, then 86 needs to ground and 85 the input from the switch.
