wiper motor connector

[amoras10]

Hi all,
Maybe where is simple schematic connecting wiper motor?
Or maybe can help me to find out which pins are 12v ground etc.? datasheet?

ps sorry for wrong topic didnt sow...

Good luck finding a data sheet.
The only thing you can do is apply 12 v to the wires and see what the motor does.
Also consider that if it is earth casing, you need to either find the wires that go into the motor and disconnect them from the casing.
May I suggest , buy motion dynamics big worm gear motors or eBay Dayton's. All earth isolated , faster and stronger motors.
And the JRK will run them.

Nothing much to see from that photo really, where are the wires? is there any kind of plastic block with terminals on the casing?

Try to find something here regarding connections

You will probably have problems with earthing, you will need to isolate it.

it is a german Ford wipermotor

if it is earth casing

it is.

you will have to open the wiper and "isolate" it. one brush of the motor will be "+" the other "-" (probably you will find 3 brushes inside - slow and fast speed). you don't have 12v and ground pins on dc-motors.



PLEASE DO THIS TEST before connect the motors to anything! :

1. Test the motors with out the Jrks plugged into it. basically if your power supply can run one or both motors in both directions, this can be do by wiring the motors directy to the power supply, then a quick on/off or diconnect your pots and test that the power supply can spin them in both directions.
While spinning test with a test light by placing clip on positive of powersupply and the probe on the casing, test in serveral spots if it lights up ya go a power leak not good will cause jrk to drop out evem blow up if there is enough amps.
The place the clip on the earth of the power supply and probe on the motor body in several spots and if it lights up you have a earth leak.
If it fails this and you cannot isolate them then i suggest finding some new motors.

thx BobBuilt

wow thanks
its really ford motor
lets try then to isolate and test

its really ford motor

not hard to guess with your posted picture actually it is a "SWT" motor ford is using - like the VAG group is using Bosch...

1) Open the case by removing the two screws. On the motors I know these are often torx screws (T27 or T30 I guess).
2) Pull the case - so the rotor is free. (You will need some force - because the magnets are quiet strong)
2,5) You will see something similar to the picture I posted above.
3) Open the case on the other side of the "output-axis" - usually you just need to pop up 4-5 plastic noses.
4) Remove the C-spring holding the rotor in the gearbox.
5) Pull the rotor. Be carefull not to damage the brushes, brush springs or the commutator!
6) Unscrew the epoxy-board (holding the electronic) and also isolate this at the bottom.
7) Solder the wires to the brushes or the board BUT make sure noting can touch the case of the motor.
8) Reassemble everything. (the part with the brushes can become quiet tricky )
9) Use a test-light and do the test above posted. If the light start to glow or just dims in one direction of the motor --> You have to start at point 1) again

Ps.: I think we need a video tut for isolating wipers!

Video tutorial would help , but I found with 4 different types of wiper motors I used in the past , none of them required me to open the casing , just cut the wires in between the plug and test to see which was the fast speed and earth.
Probably I was lucky to find motors that were easy to fix.
I was also lucky to find wipers at $10 each , as most places near me , and there are a LOT of wrecking yards , wanted upwards of $50 or more for second hand wiper motors .
Yeah right!
Mind you , these days the big worm gear motors are excellent value , stronger, faster and earth isolated.

of course dave - it would be wise to test the motors first and just open them if needed.

Hi,
yesturday i just startet with my whiper motors. Ok groundwire is soldet directly to the brush everything ok. But how do i get the black housing back on the motor because i have some problems with this little metal plate dit you first put the housing ont the motor and then put the little metal pieces through the hole and screw the 2 torx screw in? I don't get it back together maybe anyone can help me

[yokoyoko]

Yes it can be very challenging to reasemble these motors.
I always use a screwdriver under the little metal plates... you can push them against the upper housing and after carefully try to insert the torx screws. If you have enough space you can try to hold the metal plates with pilers or forceps.
