Intermittant wiper wiring ???

[kaptnkaos]

Hey Thunderfoot...

Here's what I got: bus side listed first.

#1= not used, I tried conecting the blue feed wire from the bus to the Orange/whiter wire. The motor ran full time and did not respond to the switch at all.

#2= red > red
#3= Green/black > white
#4= Lt blue > blue
#5= Black/red > black

I didn't use 7 or 8 at all

With this wiring I had these functions on the switch
Off / Nothing / High

I found by connecting a jumper wire from Lt. blue to White, I had power in the middle position as well, but no speed varation. That's what leads me to think that there must have been some sort of resistor or some thing that reduced the power from the switch in one of the postions.

When connecting the Lt blue power feed wire to the Orange/white the motor ran faster than with any other connection, but would not respond to the switch.

I don't know if there would be any other wiring combination that might work better. I tried other configurations but couldn't find any that would work.
Let me know what ya think... nothing that's been done can't be undone...

thanks again...

wow what if your going 72 two speed wiper to 73-79 itermittent wiper box, IIRC that was only two or three wires needing to be rewired.

oh bugger now i've gone cross eyed.

Hey RJ...

That should be a direct swap... no changing anything... just plug and play.
You will need to cut the shaft as shown on the tech sheets...
I put one of them in my '68 CS, it musta took me a whole 15 min begining to end.
We have been tryin' to figure out how to put one in my '68 B-500 bus...
It isn't wired the same as a pickup. The chassis is a '68 F-500 truck, but it mated with a Bluebird bus body... that's where the problem lies.
It has 2 motors and two switches (one for each side).
It's kinda a morphedite... half truck and half bus...
Finding parts for it has been a real bugger...

Take care,

Hey Thunderfoot...

Wow... dude that's a lot of work.
Thanks for workin' on this with me.
Yeah, I do want intermittent wipers if at all possible.
I can get a couple of the relays... is there a particular place to get them and is there a specific one I need? Could I snag one at a wreckin' yard or somethin' to experiment with?
I will need to get a meter... and learn how to use it, because I haven't got a clue... the only thing I know how to use is a circuit test light.. clip it to ground touch somethin' if it lights up then the cicuit's hot. If it don't and it's supposed too ... something's wrong.
It's pretty sad, my step dad was an electrical engineer and could do anything with electricity, ac or dc it didn't matter... if something didn't do what he wanted it to, he'd just fabricate something that would.
I've learned more about wiring in the past 6 months than in my whole life.
With that in mind, knowing what we have to work with ... my limited ability and the wire functions being what they are. Do think that there might be another way to connect the switches that might work better?

Thanks again,

Backcatcha Thunderfoot...

I have a regular bump wiper motor... I'll check to see if it is the same...
It seems like it is differant, but I can't remember for sure.
I pulled it about a year ago now when I dismantled the '71 CS for parts.
That would certainly make matters simpler...
I'll check and let ya know...
I have been so busy the last few days that I don't know when I'll get back over to my storage unit to grab that motor.
I'll let ya know what I find out.

Job changes are always a pain. Would this change be by choice ?
I feel really fortunate. I have a job that I like and am in no danger of layoff.
The pay isn't all that great, (but not bad either).
The benefit package is incredible. My pay would have to be twice as much to make up for it...
I get full medical/dental/vision insurance (at no cost to me),
profit sharing in the form of a 401K.
2 weeks paid vacation as well as 14 personal holidays to take when ever I choose.
In Feb, I will go over 10 years full time and my vacation time will double.
I actually went over 10 years back in March, but was part time and on call
for a few months. Even though I worked enough hours for full time, my full time status didn't kick in until Feb.

take care...

Hey Thunderfoot,

I picked up a second bump wiper motor.
Right away, it was easy to tell the differance. The bump motor has 4 wires.
Hopefully this evening I'll be able to pull one of the bus motors and see how it looks. It would be great if I could do a straight out swap and uncomplicate this whole thing.
I'll let ya know what I find out...

Take care,

Hey Kaptn,
Got my fingers crossed for ya on the wiper motor swap, hopefully you can make that work…

On my job.. I’m a FSE (field service engineer) for a company that has equipment installed at a local High Tech company here. This local company is cutting back and not buying any of our equipment right now and has canceled a maintenance contract we had with them, so not sure what my company is going to do with all of us here… As long as they still have some of our equipment, I’m sure they will need it worked on from time to time to fix what they can’t… I’ll probably be traveling some for a while at minim, hopefully know more in 3-6 months or so… until then I’m brushing up on my skills

Hey Thunderfoot...

I wasn't able to get the motor out last night.
You can check my thread "stupidest question ever".
I could't get the wiper arm off. On the bus, the motor, cam, and bracket are all assembled first then installed. You have to pull the wiper arm off in order to get to the nut and spacer that holds the assembly in place. I couldn't get the arm off for nothin'. I tried everything except "sticking my tongue up my nose" as Wes suggested. I sprayed it down good with penetrating oil this morning. Hopefully, that will help release it. I may run up to Harbor Freight and pick up a small puller, just so I don't damage the arm or post. When I took the acorn nut off, the threads looked kinda stripped. I imagine that it would be next to impossible to find another one like it, seeing as though I can't even another rig like it. If you do a Google search for "1968 Ford Bluebird bus" you get a link to the pics of my bus... That's just so wierd. I feel like "The last Mohican" or somethin'.
Not sure if I'm gonna be able to work on the bus this evening... it's pouring down rain.

Anyway, I am at woprk and gotta go...
Take care,

Hey Thunderfoot...

It's a no go with the bump wiper motor swap...
the mounts are way differant.
You can check out my thread "Stupidest question ???" for the details on that.
Got another problem.
I have to look at the the way it's wired again.
I noticed yesterday, that the motors got hot without the switches being turned on. It hasta be the constant power feed from the Lt blue wire causing it.
I am beginning to wonder if the bump switches will even work on this application.
I was never able to get the whole motor assembly out.
I couldn't get the cone piece off of the shaft (the conical shaped piece with grooves that the arm fits onto). The whole unit would come out easily if I could get that piece off.
If I could get the whole unit out, I could see if the bump motor could be made to fit. It would actually be the other way around. I 'd have to see if the mounting plate could be adapted to accomodate the bump style motor.
I might have myself another problem as well. When I reassembled the unit, the wiper only had about half of the travel as before I messed with it.
I can't get my hands up there to work and see at the same time...
I can't tell, without having the unit out, if there is another way that the cam arm can be mounted to the piece that moves the wiper arm.
aaaarrrrggg ... with a little planning they could have made this impossible instead of just a PITB...

Take care

Greetings Kaptn,

Sorry to hear that you had so much trouble there and now you have more problems… I’m starting to think I’m bad luck, tried to help Ezernut with his fuel problem and never did get him figured out / fixed…

On the wiper motor having power this is normal as it is how the park function works. Do you know which wires were hot? It should have been the Red wire and / or the Black wire if I’m correct on the function… If you get a chance, test all the wires going to the wiper motor with a test light in the off position and let me know what you find out. Also while your there try testing each of the wires going to the wiper with it “ONâ€Â

[kaptnkaos]

Hey TF...

It certainly isn't you...
I think I'm gonna see if there is anyone working at the school bus garage. Probably not, since it is summer time, but ya never know.
I really need to get that whole unit off so I can get it put back together right. It feels like there is another hole that the bolt could go into, but I can't get it to go in because of the lack of clearance.
There is an upside down U shaped channel that covers everything.
The motor bolts to it with the cam piece on the inside. The rest of the linkage attaches to the cam. The shaft that goes thru the cowl comes out of the channel on the opposite end from the motor.
You can't remove the screws that hold the motor in because you can't get to them with the unit installed... aaarrrrggg
When I get a chance, I am gonna try messin' with the cone piece (not sure what else to call it)on the shaft outside again.
If it is compression fit, then it has to come off somehow.
I am gonna try using an open end wrench smaller than the cone piece and a small block of wood, and a DBH (Dang Big Hammer) to see if I can get it to come off. With my luck, it will shoot off there so far I'll never find it again...
It's raining here now so it probably won't be until next week before I get to mess with it again.
This weekend I'm gonna take a road trip down to Oregon and hook up with a couple of buddies from high school. We try to do that once a year on the 3rd weekend in July. We weren't able to get together last year so were shootin' for this year...

I'll let ya know what I find out about the wires as soon as I can...

Take care and be blessed,

Hey Thunderfoot,

I haven't had much time the last week or so to get out and work on the bus.
I contacted Bluebird bus about the original bus switches... they of course don't have anthing or any information about the switches.
They did give me a number for a company who might either have them, or info on them. I called them yesterday and they asked me to email thyem some pics.
So, last night, I got the original switches out of the bus, cleaned them up and took a few pics. I tired to email them, but my message got returned as undeliverable. I musta wrote it down wrong, 'cause the address I sent it too was the same one I had written down.
AFter cleaning them, I was able to find the brand "Cole" outta Boston. I did an internet search and the company is stil in business, so I am gonna try to contact them as well.
I disassembled the switch that didn't work, amazingly simple... no resisters though. I did find out that two of the terminals are bridged on the outside of the switch. I made a diagram and am attaching a pic of what the parts looks like. In the pic... the image in the upper right is the back side of the second switch. The image on the bottom left is what that piece looks like on the inside.
After taking the pics, I reassembled the swicth and now it feels like it might even work, though I haven't smoke tested it yet.
Let me know what ya think... is it possible to make the IWS work with this configuration...

Thanks once again,

Hey Kaptn,

Had to think back a bit on this…

From the info you gave me in the last post, I got a better idea and would like you to try this wire combination to see what happens, using the stock bump switch that you have in it now. If we can get it working on these then it may work on the intermittent switches…

Try hooking up the wires on the stock bump switches like this and let me know what happens… Use the same layout I posted in post #14 that we went off of before…

Bus side listed first

#1= Lt Blue > Orange/white = power supply
#2= Black/red > red = park power
#3= Red > white = low speed
#5= Green/black > Blue = High speed

#4, 6, and 7 = Not used

[kaptnkaos]

Hey Thunderfoot...

Yeah, I will try that...
It probably won't be until this weekend. I am busy the next two evenings after work. Hopefully this will work...
I thought taking the one apart, might help to at least figure how the original set worked...
When I saw that small piece of copper bridging the power and park terminals... I felt like a break through had occured.

I try connecting everything up agian and see what she does...
Hopefully there won't be a big puff of smoke...
back in the day smoke testing something had a whole differant meaning for me

Thanks again,

Hey Guys...

Just a quick up date on the intermittent wiper project on Olde Skool.
I determined today that it ain't gonna happen...
At least not by using bump parts on that morphidite sucker...
If it had Ford truck wiper motors it would been done a long time ago.
But... no... it's got some kinda morphidite ones that no one can even identify... grrrr
I just gotta say publically... Thunderfoot has got the patience of a saint..
As a result, I learned how to repair the ones I have...
Which is cool, because they can't be found anywhere in the country... After reinstalling the repaired original switches, I now have two speed wipers on both sides... yes !!!
