I can't get the high speed motor on. It operates in low speed. Is there a wire diagram?

My database only shows one wiper motor. Did you check voltage and ground, anywhere? Check the wiper fuse for voltage, hot all the time, use test light. At the wiper motor, dark green wire is voltage for lo speed. The purple wire is voltage for hi speed, Turn on key, turn on wiper switch, probe those two wires for voltage, use a test light. That bottom black wire off wiper motor, in diagram, is ground, check that also. If good voltage and ground with no wiper action, I suspect the wiper motor. There are codes for wiper, manufacturer codes, check for codes. good luck

Well, a Fasco is a generic brand name of HVAC replacement motors.... a little more information would be helpful....like the wire colors???? Each Fasco motor has a wiring diagram on its side and is self-explanatory. Post a picture of the diagram and it will be much easier to walk you through the procedure.


But TYPICALLY....white is common
black is high speed
red is low speed
blue and yellow is medium low and medium high
two brown wires go to the capacitor

Some manufacturers have oem motors that have a few different colors.

Each motor will have wiring diagram on label.
Compare diagram on old motor with new motor.

WIRE COLORS VARY
Which 2-speed timer do you have on the circuit?
Wire lead from NO terminal connects to High speed.
Wire lead from NC terminal connects to Low speed

The motor will have wiring diagram and voltage on nameplate.
You can re-post question with information that shows on nameplate for more exact information, or keep reading below:
If motor is rated for 240Volts, then it will not work with 120V.
If motor is rated for both 120V and 240V, then either Low voltage or high voltage will work, and one wire will be common, and 1 wire will for 120 and other wire for 240.
If motor is rated 120Volt two speed, then one wire will be neutral, and 1 wire low speed, and other wire high speed. You can connect your wire to either low of high, and cap other wire.
If motor is 240volt two speed, then one wire will be common, and 1 wire low speed, and other wire high speed.
If motor is rated 3-phase, then all three wires are connected to the voltage shown on nameplate.
If motor is rated 3-phase two speed, you may need electrician to wire the motor correctly.

There should be a wiring diagram on the motor itself. The colors of the wires vary depending on voltage and model. Generally you have a med/low and med/high setting, I'm not sure what you are getting to with the low/high setting unless you are trying to set up staging. Check the motor for a diagram, if that is not present post back with all of the wire colors coming from the motor and the voltage.

all US motors should have a wiring diagram on the side of the motor unit. The wires going into the pump would hold their same values. I am assuming the previous pump was two speed as well, if not that is your problem.
assuming that they are both two speed reference the common on the pumps motor diagram, and connect the white wire to that terminal.
reference the diagram for correct low speed and connect the black wire to that termial,
repeat for the high speed.
I deal alot with the flo master pumps and they should all be labeled. The most important thing is to get the common correct, switching the other two wires (black and red) incorrectly would simply result in high coming on when low is supposed to and vice versa.

If there really is not a diagram, here is the most typical setup for that motor.

(if you look closely at the terminals on the motor, there are numbers there)
connect the white common to terminal #5
connect the red hot wire to terminal #1
connect the black hot wire to terminal #2
connect the ground
done

Hope this helps.

The side of the motor will have a wiring diagram for how to connect the common, low and high speed leads. Your wire harness should have a white (common), black (usually low), red (usually high) and green (ground) wire. If high and low are backwards, switch the black and red leads.

high speed phase neutral should go to High speed {phase} neutral low speed {phase} should go to neutral .....Low speed and high speed {phase} need not be connected

Typical Diagrams Will Be As Follows

C - Common
H - High Speed
L - Low Speed
_____________

W/white - Common
B/black - High Speed
R/red - Low Speed
