    Re: Delay switch:

    Sorry - standard delay switch won't work with the Series wiper motor. These
    gadgets rely on the "parking" switch on the motor to do their cycle, as all
    they do is switch a pulse of DC power to the motor to get it off the park
    position, then the motor does the rest all by itself.

    The Series II/IIa wiper motor doesn't have that facility - there's no park
    circuit. Yes, you can add that too, but it would be an annoying fiddly job
    at best to get it to work and aligned.

    If you want to slow it down a resistor in series with the field winding is
    likely the best bet - that would reduce the motor speed, but those motors
    are pretty marginal performers at best - with a dry windshield you're
    likely going to get stalling on start .

    Were I you I'd not worry about it....just my .02... -ajr
