First thanks for the help with understanding adding relays to various
circuits. THe web site I was directed to (you know who your are) is
excellent. I have everything figured out except the wiper circuit. My
wiring diagram shows 5 wires to the wiper motor. 1. Black-ground wire; 2.
Green/pink - common to a number of circuits including the washer pump and
then three other wires coming from the wiper switch. 3. blue/light green;
4. red/light green and 5. brown/light green.
I need help here. The wiper is supposedly two speed. (I have slow and
slower).
Is the speed of the motor changed by tapping on to the motor coil at a
different location? Don't you change the speed of a DC motor by changing
resistance? Why three wires from the switch? Do I put a relay in the
system between each wire of the three wires running from the wiper switch
controling a direct power connection?
Hopefully my ignorance makes sense to someone. My wiper circuit would
benefit the most from some good power direct from starter through a relay.
(fused of course)
