Just hook it up, then hook up the battery and pull the knob out! You are way over thinking this.

Was in the neighborhood of Joe’s Auto Electric today and hoped to have tales to tell about our generator.

Unfortunately, could not make it there before closing so it’s been back burnered again.

Will be back around there beginning of May to finalize my robot project and will try again.

Back to the wipers tomorrow.

Wiper Day

As I could not get the motor to move on 12 volts, pulled the cover and had another look (had replaced the 6v armature with 12v a while back).
With my newly acquired electrical knowledge, I immediately saw that I had not arranged the brushes correctly, they were resting on top of the armature instead of pressing against it.
This gave me hope — rearranged them and gave it another shot.
Nada.
Thought the brushes might be corroded, so lightly sanded them.
Nada.
So I attempted to turn the wiper by hand — it was quite difficult so I sprayed a bit of WD40 at the juncture where the actuator meets the body and tried again.
It did move but only a bit, each time I applied the voltage, and then stopped.
So I spent some time working the actuator by hand to free it up more and sprayed electrical cleaner on the contact points.
Better but no cigar:


Link


I am finding continuity between the hot connection and the grounding body with about 2ohms of resistance. That would lead me, via ohms law, to expect 6 amps. Getting .6 ish so I must be reading the ohms wrong (0.2 ?) or the display is not in whole ohms?

Anyway, any thoughts would be appreciated. My next thought is to remove the armature and check out greasing.

Have you removed the base plate to clean the gears and replace the grease? Over time the original grease tends to solidify and keep the gears from moving smoothly.

Yes, I believe I did this but I will check again.
Thanks Loren!

Moving forward.

Guess I can put the visors and rear-view mirror back:

Went to my local hardware store and found rubber washers to use instead of the grommet that doesn’t fit. Seems to be more like what was used originally anyway (5 & 6):

Put some permatex between them to finesse a grommet.

The white nylon bushings for the wiper control rods don’t fit either— not in the hole or on the wiper hub. (For your reference, those white bushings in the baggie):

Luckily, the wiper rods seem to have serviceable ones installed.

So, got the hubs on:

And the wipers:

I am sure that there will be adjustment fun when I get the motor installed.
But, there they are.
Silver wipers.

Your Ghia is looking great! A note of caution on the visors though, you might want to leave them off until we source the attaching hardware, especially the pieces at either end. Without these pieces in place to support the visors they might crack or break when the Ghia goes over a big bump.

Darn!
Ok, before I go for a drive, if the hardware is still not there, will pull them but leave the mirror.

When you finally succeed with getting the motor to go, have the wiper arms off the screen just in case you have made an error with the motor arm and linkages. The error could send the arms downwards to the paint rather than upwards to the glass. Not a problem if the arms are lifted and away from the paint.
I encountered this during my foray into wiper motors and found the nicest looking one in my small collection was the worst one to use because it pushed in the wrong direction.

That was my plan, Nicolas, but had no clue just how bad it could have been.
Could you have reversed the polarity by exchanging wires on the brushes?

Pulled the base plate on the wiper motor.
Yuck:

Cleaned and greased:

Now works like a charm including the self-parking circuit!

Now I need to get/fashion a grounding tab. And figure out what bolts are used to attach the motor to the bracket.

Had a thought for grounding the interior light.
Attach the ground wire to this piece that I crimped and slide it on the framework provided for the light:

Well, darned if I can find any information regarding how the wiper motor is bolted to the strut.
Screw? Bolt? Washer? Size? Direction?
I’m sure I could just wing it but I am equally sure I will get called on it if I do.

The screws are "cheese head" screws. They have a round top with a slot, very similar to the screws that hold the engine tin together (you might even be able to use engine tin screws). Though it doesn't have a clear image of the screws this post might help with some of the original details for the wipers and wiring:

I know that area's on the inside of the body is going to be covered by rubber or carpet and unseen, but it too deserves some TLC and to be cleaned up and have a fresh lick of paint to seal the metal.

or am I just OCD? anyway that's what I would do.

Thanks Loren.
Went to the hardware store before your response and gathered hardware that I thought might work but would much rather get it close to right.
Tried the cheesehead screws for the tin but try as I might it seems that they may be just one size too big. Will try again and, if no luck, will seek out the right size.
Surprised to see the rubber — as it doesn’t seem to make sense to electrically isolate the motor, I gather it is there to help dampen vibration. Will at least add some rubber washers.
Also tried to sort out the wiring for the motor. Not sure the harness came with all that is needed but I have plenty of wire to spare. Have a screw terminal switch on its way.

Tried out my idea for grounding the interior light. Works like a charm so that portion of the project is complete— all three positions of the light switch work.

Moving on, decided the next easiest harness would be the headlights.
Pulled them and had a look-see:

Interesting that you bring that up.
Asked Dwayne what I should do to keep up our car’s finish. Was surprised when he just said to keep it clean— doesn’t have a can of wax in his shop.

Commence comments.... now!

well i agree to a point. Any fresh paint should be left alone for awhile and im sure anything he buffed will be fine for just as long. Depending on times used and how dusty things get in your garage maybe keep a car cover over it and get one of those dusters for it. Eventually i would think you would want to throw a coat of wax on it just to seal in all of that red goodness and keep the bad guys off of the paint! unless they gave it a ceramic coating which i think can last awhile.....
