Terminal markings
The terminals on the engine are standardized as follows. The numbers in bold are standard designations, the numbers in brackets (...) are Ford designations.
Terminal 31 (3) is a terminal for connection to the housing (in general in the electrical equipment of vehicles).
Terminal 53 (2) - receives voltage for the first windshield wiper speed.
Terminal 53a (5) - supplies positive current (+) for resetting the windscreen wipers: the motor receives voltage through the sliding contact until the windscreen wipers are in the reset position, if the driver switches off the windscreen wipers.
Terminal 53b (1) - supplies voltage for the second speed of the windshield wiper (parallel winding).
Terminal 53e (4) brakes the windscreen wiper motor when moving backwards after switching off, so that the windscreen wipers do not leave their stopping position.
Checking the windshield wiper motor
First of all, find out if the windshield wiper motor is working properly and if the electrical system is OK. To find out, do the following:
Pull the multi-pin connector away from the windshield wiper motor.
Using two auxiliary wires, supply voltage (+) and ground (-) from the battery to the wiper motor.
Place one wire from the positive pole of the battery to terminal 53 (2) or 53b (1).
Run the second wire from the negative pole of the battery to terminal 31 (3) of the engine.
Now depending on the terminal used, the motor should run in stage I or II. If the motor does not run, then the motor or the corresponding stage is faulty. Remove the wiper motor, see item 23.5.
