Greetings & Salutations
I have scanned in the wiring schematics from a “Motor” Professional Mechanics Manual from 1985. According to the manual and Bosch propaganda this schematic should be good for 1984 -through- 1987 190-Es. I scanned them in large and each individual Wiring diagram 1 -through- 5, look great imported into MicroShaft Publisher on 14” -by- 11” paper.
Then use this Web Page for troubleshooting:

Having decent schematics sure makes a difference compared to what the Haynes manual illustrates.
Happy Troubleshooting Folks
