You are soooooo right Mike...I should be shot or at least beaten to a pulp for not stating that my car is a  66 coop withh no doors, hood, fenders, engine, trans, MC or booster, brakes, seats, glass, waring, trim, gas tank, deck lid, grill, lights of any kind, wheels, or tars, or a radio or glove box door, or steering wheel or box.  It also doesn't have a windshield wiper motor but I do and it don't work rat.

The one I have is from a 66 coupe, mine, that has a lot of new metal and a fresh paint job...see my abattoir, ah I mean my avatar, and is a two-speed...the wiper motor not the coupe...and it runs bass-ak-wards to park...the wiper motor, not the car which is permanently parked due to all the suff mentioned above that it ain't got.

Thanks Howard.  Yup, I bench tested it with the factory harness and the gound connected and the motor case gounded.  HMMM, didn't gound the switch, I wonder.  Naw, it's been doing this since we bought it.  Behaves on the bench exactly like it does in the car.

So you got a 2 speed electric motor running your car, every time you shut the motor off the car backs itself into the garage. Got it. The only thing that I know that can reverse a DC motor is flopping the politary. You got something hooked wrong. Best I can tell from these crumy schematics, the 1 speed motors use ground to park the wipers. The 2 speed motors use positive. Do you have some type of hybred. Maybe this can help. There is a little more going on than I have marked but this is the just of it.

Talk about picky.  At least yours turn off when you turn the switch off.

You guys keep me entertained.  Keep up the good work !

I had talked about mine that would not shut off when they were wet.  The other day, I washed the car, purposefully did NOT turn on the wipers because I did not want to have to deal with them not shutting off.  Guess what... They came on by themselves and then went off after the car was dried.  Never touched the switch, and no water is getting under the dash.

Duh...The two wires that are tied together in low or high are the  field wires.  It ain't a PM motor...it needs a field.  Speed is controlled by the voltage applied to the armature, hence the the low speed wire goes through a resistor and the high speed wire bypasses the resistor.

If I'm reading your skizzy right, Walt, there should be a ground source at the switch so today I'll be doing more experimenting on the bench.  Terry says  his does this depending on the position that he turns the switch off. 

More to come.

After scratching my head until I have very little hair left...and some of you know that I had little to start with...I have determined that the switch reverses the field current in the off position which could have something to do with the motor reversing. 

I have decide to live with it and make the conversion to a 67 motor one of my winter projects.  Ford must have hired some confused, mental deficient electrical engineer to figure out how to do a two-speed, self parking wiper motor for 65-66.  ...  But hey...Ford's system used twice as many wires to do the same thing only not as well.

I like your attitude and your humor - helped put me in the right place with some issues I'm having with mine (not wiper-related though :-).  Thanks!

My 66 coupe wiper goes back wards when turned off=thought it was normal....lol
 

According to  CJ P-Parts, the same motor was used in Mustangs from 67 to 73 (I think) and from 78 to 86 (same as the 67) and they sell a "rebuilt" one....cleaned and  painted....for $75.  It's a four wire unit (low, high, park, ground) which is fairly standard.  The 67 + mustang switches are slide type or  something else other than what the 66 has but I'll bet I can find something that will work or make it with some lathe work and some microswitches. 
It would be nice to compare that truck unit with the 67 Mustang.  Also, what kind of switch did the truck use and did it have a washer ckt in the  switch? 
I may take you up on you always kind offer but  this will be a winter projectd.  No more custom stuff now.
We'll cuss and discuss this at the bash.

Thanks again,

BB
 

Thanks Walt.  Don't know why I didn't know all of this, butt (TS&T) I didn't.

BB

Thanks very much, Steve.  I'll be  perusing that info tonight.  Gonna make a decision since now is the time to get it right.  Wiper work after it's back together ain't no fun.

BB

You know, you are probably right.  Sure is nice to have a 'tronic wizzard on the forum.

I may check that  out tomorrow.  But, I gotta tell ya Walt, I'm seriously considering going to the 79 F150 setup with intermitant, two speed wipers.  Might as well get it done now while there is nothing under the dash.

       BB Just sent you out a switch with delay box from a 70's ford truck. I never tested these but should work. If you use it fine, if you don't bring it to the bash. I just bought a used wiper motor on ebay. I bought used because the pics I see at the parts stores don't have a connector on them. Guess you can put a different style connector on it if you want.
