68 wiper problems
Got the vacuum schematics-- thanx Ernie.
Did a bench test via Wilcox's papers and the motor works fine. Put it back in the car and all I get is a clicking noise and not from the motor.
The motor also starts to smoke a little. 
I don't know why it wants to smoke but I think the clicking is the solenoid in the console. Damn I don't want to take that apart again Where can I ground my gauge console top and bottom to? The unit is broken into 2 pieces AGAIN. I believe I have to re-ground the top part don't I?
How can I test the switch to see if it is working properly. I thought maybe running seperate wires directly from the battery to the switch. Would this work?
I'm sure I will have LOTS more questions but here is a start.

I had similar issues with my 68, and it turned out to be a grounding problem
My gauge bezel is broken also, ran a wire from one of the attaching screws on the wiper switch down to a grounding point the console, also make sure that **** under the steering column is turned the right way and grounded also

The clicking you hear.. are you sure it's on the inside of the car and not the motor?
This is important.. post back Clifford.

Ughh... what Roger said.. ha ha ha guess we posted at the same time. If you loop it to the pod screw it will pick up the ground wire Roger is talking about.

Try doing a search on this forum, i believe I placed some info on switch testing with in the last year for another 68 lover, they can be tricky. smokin motor in car and not on bench means wire error most likely. I'll keep chicken back if you havn't solved your problem. PS and thanks to Wilcox for his well recieved tutorials.

Okay. I grounded the switch as suggested to the black 14 wire off the temp plug to the switch mounting screw. Still nothing.
I want to verify that I have these plug wires installed correctly.
Red and black is from motor. The white (looks yellow in pic) is also from the wiper motor.
The clicking is definetly coming from behind the console from this unit. This picture is from when I had the dash apart. Today I just reached behind the console and put my hand on the unit and could feel the vibration as it was clicking.
No motor smoking today.

Clifford..
Sit tight.. now that I know where the click is.. I'll figure this out..
I should be able to replicate this on my test machine (frankenmeter II) and should be able to tell you exactly what caused it. I'll check your wires tomorrow.. it's an eye thing for me this late.

Ok.. just some ideas..
Make double sure you have the switch connector on the switch correctly. There is a stop bump on the switch, and there is one on the connector. They should be opposite of each other. For a picture of this please review my article on the 1968 motors where I have a picture posted. There is an even better picture of this on the 1969-1972 article.
The wires should be:
Black to Blue
Red to Red
Brown to Brown.
Now.. without turning on the wiper motor.. turn on the key..
Key on.. and testing at what I've always called the 123 connector for the wiper motor... I get the feeling this is a simple wire issue or a bad relay.. so.. lets start with the voltage test.... and you'll find the other readings in the article on the very last page.. but start with the first one.
Green wire.. no volts
Yellow.. 12 volts
Blue... 12 volts.
check these.. post again.. I'll be watching..

this confuses me Can you please be more specific. I don't have a brown wire or a blue wire coming off of the wiper motor. Just a Red and Black from the same spot and a white from the other side of the motor.
Thanx Ernie, I'll have time in the morning to work on this. I can check the votls on the 123 connector but please un confuse me on the wires.

Sorry they are a bit blurry.
This is the connector from the harness, again blurry. Brown at the top, Red at the bottom right, and there are 2 Blacks at the bottom left
Looks like it should be
Brown-Brown
Red-Red
Yellow- 2 Blacks

What is causing the confusion is the wires and colors.
On rebuilt motors some suppliers don't realize the brown wire is brown and replace it with black and the white sheath wire can be blue.. so I can understand how this is confusing... hell I'm getting confused..
On page three and now pictured below is an original 68 wiper motor un-modified with connector. Hard to see but it shows the white sheath on the wire and also details on how to establish which wire goes where by location off the motor. This should help... (also look at page 7) there is a drawing that will help you)
Here.. I just made a new pic.. I have to scoot.. but I'll check back later..

GREAT. Now I have the three wires plugged in correctly. (they were wrong) Thank you both Ernie and Rick. Now to get out the volt meter and take some readings. Will report back later.

OK got some readings. I'm not a whiz with a volt meter so the settings on it are: 2000, 200, 20, 2000m, 200m
I put it on 20 and got the following readings:
Key on:
Green -0.02 Yellow +12.8 Blue +12.6 (all on 20 setting)
Key on, wiper on high:
Green -0.01 Yellow +12.55 Blue -16.2(meter on 200m setting for blue)
Key on, wiper on low:
Green -0.01 Yellow +12.5 Blue 0.00 (all on 20 setting)
Battery was fully charged.... just pulled it off the battery charger.
I hope you understand these #'s Ernie..... cause I sure don't.

After getting the above voltage #'s I had another friend (electrician) come over to dbl check my work. We came up with the same #'s (close enuf) so I knew I was doing it correctly.
I AM AN *** I AM AN *** I AM AN ***
Then I thought I would try the overide switch under the dash and WOW the wipers work. (I thought it was in the off position but obviously I was wrong) Motor turns over continously...... with the key out of the dash and the dash switch in the off position. with the key on and the switch off or in low speed it runs continously and with the switch in high speed then it does go to high speed. It might do this with the key off too but I didn't check that. (can do if you want me to)
So now I have them working
but can't shut them off. Here's another picture of that 3 plug.
The lines in the pic signify the color of the wire.
At least I have it working now just can't shut it off. If I disconnect the black wire coming from the motor to that 3 plug then it just shuts off.... doesn't park just turns off.
