When hooking up the wiring on my console there was one black wire that just has a flat contact that had about a 120 degree bend in it that was sandwiched into a connector I believe. I failed to label it, but now I am thinking I hooked it up wrong. My wiring diagram doesn't seem to show it. I sandwiched it into the ammeter gauge plug black wire. I'm thinking this might be wrong now. Having trouble with the wiper solenoid energizing as soon as the battery is hooked up, which turns the override light on. I've looked at other posts about this problem, but my specific problem is I have the 12V from the light switch to the wiper motor, but the brown wire gets 12V on it with the wiper switch off. I'm starting to think that one wire that I wasn't sure about might have been supposed to be a ground instead of going to the ammeter black wire which eventually ties into the red starter motor wire. Might be putting battery power on what should be a ground wire. I wanted to see if anyone here might know what that wire is before I pull the console out again. Judging by the length of the wire it seemed like the logical place to go was in that connector on the ammeter gauge, but now I am starting to doubt it, even though both wire are black, which usually designates ground wires. The wire in question goes to a capacitor that is mounted to the back of the gauge panel.

 

youb dont happen to have pics of it do you?

 

Yep, a picture would be helpful. Just spent lots of time working on my wipers and wiring so if we can see what you're writing about, then might be able to assist.

 

the wiper solenoid should receive its ground directly from the "wiper motor" signal,
meaning the wiper motor is running, which should keep open the wiper door solenoid.

 

FWIW: it sounds like you are describing the console plate ground which plugs on to a spade terminal on the underside of the plate.

 

Figured it out, it is a shunt for the ammeter gauge, so I had it wired up right.

 

Will have to look at this further once I get my battery recharged. I installed a new wiper motor and gear assy., because the original one's 3 prong plug pretty much disintegrated when disconnecting it. I had to install male power plug off original motor onto new assy.,. Wire colors were a little different on new one, had black and red coming from motor along with a white wire. Based on Wilcox's diagram I'm pretty sure I got it wired up right, but with my wiper switch off, ignition switch off, I get 12V on the red wire from the light switch, which is correct, but the brown return wire from the motor is powered up, which is energizing the solenoid and turning the light on. My switch doesn't feel that great, but it did work before the frame-off resto. I will ohm out the switch since I have the console half way out already, and go from there.

 

Editted, too much cough syrup

If you haven't already, disconnect the plugs and do the Willcox bech test with the motor in place. Looking at my wiring diagram you could have crossed the red and the black wire which could possibly feed back wards through the motor and put power on the brown wire with the switch in the off position without it actually running. Don't think so but worth checking first.

If it is all set then plug it back in and try and follow the rest of my rambling. Where's my cough syrup.....

What happens when you start the car, does the wiper system start automatically? If you unplug the wiper switch does it stop? Is your wiper switch grounded well?
If it stops it's probably a bad switch.

If the door limit switch is open or the overide switch is open, the light is the ground and will light up. So with the door shut this is correct. The brown wire shouldn't affect that. The brown has power when the motor receives a signal that closes the intrrnal relay saying it wants to turn on. The brown sends power to the tach solenoid which controks the vacuum to open the door. That wire is receiving power from the red internally to the motor when the wiper switch is in one of the on positions, it receives a ground to the motor through the wiper switch. The black wire is a ground to the housing. 2 different systems. So your plug should be right,but......the only way to light that light is if one of those 2 switches is open, and the motor has a ground from the wiper switch.
Do you still have your problem, i would look at the wiper switch.

Is your wiper switch new if so find a used oem, I did and it solved a lot of problems. The Chinese ones are junk, mine failed after 3 times function testing it.

 

Lets see if I have some answers for you. So which way is the override switch open, cw or ccw? I'm assuming closed contacts are for normal operation so need to know what position that is although so far I have tried that in both positions and it doesn't make a difference as far as the solenoid energizing as soon as the battery is hooked up. Vacuum actuator for the door has a bad seal so I do all the testing with the door opened manually and the limit switch closed which has been tested and it is good. Solenoid is not energized when I disconnect the plug to the motor and it does energize when I short the red and brown wire together which it should, because that is simulating that the power to the motor is there. My question at this point is should power to the motor be feeding back to that brown wire with the wiper switch in the off position. There are three wires going into the motor, red and black from the same spot on motor and a white wire coming from the bottom of the assy. somewhere. I have it wired red to red, black to brown, and white to black right now. Is this correct, or should it be red to red, white to brown, and black to black? I won't be able to get back at this until Friday. I will start the car with the door open and the override switch closed,(whichever position that is) and the wipers switch off and see what I get. Shouldn't get an override light or any wiper motion. Meanwhile I will check that the switch has a good ground at the housing, and if not add one, and also check the switch to see if it ohms good. You wouldn't happen to know how to ohm out the switch? Black wire is supposed to be slow speed and LBL is high speed, DBL is pump,(not worried about that) I'll look at the Wilcox diagram again, cause I'm confusing myself trying to figure out the logic on this.

 

ill check mine and try and post my diagram

 

to over ride the system, turn it towards the radio, if you put a white dot on it, it would rotate towards the center of the car.
red to red, black to white, brown to black

 

the switch is connecting the system to ground, its just a pathway, so it should be infinity or 0. Yes the 68 motor gives everyone headaches. I would do the willcox bench test, your motor could be bad

 

What a difference a day makes. With wiper door open and override switch CW position wipers worked and override light was not illuminated. Just tried it with ignition on. Have it wired red-red, black-white, and brown- black. Battery won't hold a charge long, went down to 10 volts with one cycle of the wipers, so will have to look into that. It's 4 yrs. old. Thanks for all the help with the correct wiring of the plug, that was the one thing I was unsure of. Kind of strange about the override switch though, since I had it CW and everything seemed to work right.

 

if that over ride switch is left in the ccw position it will drain your battery. I would turn it all the clockwise and put a white dot of paint on it so you can see it from the drivers seat

 

So CW is the normal position to have it in, good to know. Mine is missing the **** so not much chance of it getting inadvertently moved unless you really want it moved. In all the years I've had the car I never even knew what that switch was for, let alone turn it. Thanks again.
