    Default Pug 403//404 wiper motors

    guys....

    my 403 uses a single wire wiper motor with an external wiper switch to ensure proper park position.
    i have found two other wiper motors at a local dealer here. A 2 wire wiper motor and a 3 wire wiper motor.
    Pictures attached.
    1) Anyone here has any idea which model these motors belong to?
    2) The extra wires for higher speed or built in park switch?

    planning to try using a proximity switch to replace that park switch.

    Extra wires are for built in park switch.
    These motors work a lot better than the earlier ones.
    You will need a double throw double pole switch to make this work in earlier car.

    You don't need a external park switch if you use the 404 wiper motor. It has an inbuilt park switch. It's also a lot more powerful than the original.

    Attached is the 404 wiring diagram as a guide to the wiring. Don't forget to earth the case as well.

    Thanks Graham and Rob...great info.
    have purchased the 3 wired motor, last piece he had, but he has numerous two stub motors. I did get to open one two stubs motor, surprisingly the motors have two stubs for wire connections, but only one is hardwired. The other is just stub without any wire connections.
    Rob... i have a 1968 404, even this fellow uses a single wired motor. Sigh.....

    The on off switch is very different though, the DPdt switch I referred to. You can either use an original switch from a late model car or buy an aftermarket toggle switch of the type mentioned above.

    Yes they have a weird parking system where you need ground (?) the park switch wire when the motor is off.

    Whereas you apply positive to run the motor.

    Best to fuse or current limit your bench test supply, otherwise you are guaranteed some smoke and heated wires whilst working out what's what's.

    Yes, the motor is shorted out when the power is switched off, it is then in generator mode.
    The high current generated by the motor in these conditions and the resulting magnetic field means the armature will stop turning in a short period of time.

    It's a form of dynamic braking and has long been a method of slowing down shunt field brush motors.
