Kirby Commercial Cleaner Motor Wiring Diagram

[kirbyclassiciii]

For all those of you that own at least one of the following -- Kirby Janitronic, American Lincoln Super-Sweep, Super-Vac 180 and Kirby COMVAC 1300 -- here is a sketch I did for the motor wiring diagram covering these machines.

Please let me know if I got these 100 percent correct.

Pretty professional-looking... looks like you copied an existing diagram lol. This implies these vacs have a normal 120v light bulb, good. I think the 12v ones that require an extra motor winding make the machine needlessly complex for no reward.

I would've drawn the LINE differently. As it is, it looks like it's a load. The input power is drawn differently, often. Usually Line and Neutral are drawn as two separate dots. But I'm just picking nits.

Plate

They attached a ground wire with a gold or brass ground terminal on the switch.

Les,

On all Super-Sweep models from serial no. 110001 (the army green/D80 trim version), yes, they used a three-wire brass ground plate (1110) which is simply mounted on top of the foot switch using the same two mounting screws (1125).

In original production, the field coil used on these commercial cleaners came with two terminal clips that were soldered to the yellow and red wires that connected to the top and bottom carbon brush assemblies (respectively) on the motor housing. But in replacement, the field coil (which is exactly the same as for models D50 and D80) does not have these; therefore, if confronted with replacement, you must also order two terminal clips, which in this case must be soldered to the yellow and red wires: the field coils on the pre-1979 models (serial no. 210000 and lower) will have the same style terminal clips as used on Kirby models 519 to D80 (part no. 104559), whereas those built 1979 and later (serial no. 210001 and up) use the same style of terminal clips as found on models Classic 1CR to Heritage II (part no. 104569).

Yes, I do believe I can fix the schematic part for the green (ground) wire.

I'm posting pics from my thread of Comvac/super sweep.
Red is likely a power wire. One red comes from carbon brush clip the other off the coil. The headlight is white and black direct connect to the switch. Black and white from coil to the switch. Orange is ground from the carbon brush clip.
I believe the orange wire connects to the brass ground plug/prong.
Its basically your diagram with color variations.

Les,

That is odd that Kirby would change the color of the top carbon brush wire on the field coil from yellow to orange for the 1979 and later machines (part no. 103977).

Umm

Im guessing on a theory.
I know there is green white orange cords. The green are what you use for example Christmas lights. They are resistant to freezing water etc. White is usually indoor type items. Generally indoor not weather proof wires. I believe orange is used in longer extension cords that are grounded. Example would be a construction site with a grounded plug.
I'm guessing they changed it because commercial application or electrical certifications use the colors for commercial grounded wire.
It could be green for consumer and orange for commercial.

1300

That sure is a clean ComVac1300! Lucky devil who has that!

Les, and Chris,

According to all the distributor catalogs I have read, they say to use the 103967 (1332-1A) field coil in replacement, even in the years when the original ones (103966 and 103977) had been made. Some parts were exclusive to original production.

You just might be correct about the original commercial-use field coils having the orange wire substituted for the yellow one. However, I have not yet seen an original field coil from a pre-1979 Super-Sweep yet.

The benefit of the later 12V bulbs is longer bulb life due to a thicker filament. They were probably cheaper, too, due to it being just an 1156 auto back up bulb.

 

[lesinutah]

Cheaper

There only cheaper now china isn't able to flood us with led bulbs.
Yes I heard the 1300 was new in box.

Les,

Now I see about the other shorter red wire running between the foot switch and the carbon brush assembly. I think that might also have been part of the changes for the 1979 Super-Sweep. Anyways, the carbon brush caps (this design dates back to the Kirby Classic Omega 1CB) have a 90-degree slant on them.

Les,

Also about that short red wire: being the ground wire, it would also have a brass lug that must be mounted on the foot switch before the cover and brass plate are installed; I see it is held down by the lower of the two screws on the switch.

~Ben

 

[lesinutah]

Correct

The brass plate is held by two screws and the lug goes over the top of it.
The switch iirc has hhhh wwwww and two gg
Hot neutral ground. The red goes into one of the two g ports. I just assumed incorrectly on the red wire.
I think it's the screws holding the brass plate and on top of the plate is ground lug . The screws I'm pretty sure are brass and are used to attach the plate and lug all while grounding the prong/lug on the body of vacuum via the screws.
Nice catch but you catch everything.

Les,

The 1981 Southwest Manufacturers & Distributors parts catalog has a wiring diagram drawing for the Super Sweep. That is how I came up with my version of the drawing.

But, thanks to you and others, I am going to make a new version of it to reflect also the short red wire that goes between the foot switch and the bottom carbon brush assembly.

Thanks for posting the diagram. I thought with all those catalogs I ordered it would had one but you found one.
The commercial had to have different colors. The heritage 2 legend I looked at today it was like the tradition.

Les,

I have noticed recently that some of the connections by the foot switch are actually soldered together, or actually emerge from the field coil itself, including the yellow/orange and red wires serving the top and bottom carbon brush assemblies respectively (at least these two wires might be soldered).

There are only four direct connections to the foot switch:
HEADLIGHT SOCKET
* The white headlight wire into the third "W" slot.
* The black headlight wire into the second "B" slot.

FIELD COIL
* The white wire from the field coil into the first "W" slot.
* The green wire from the field coil into the first "B" slot.

The brass plate for the 3-wire cord set apparently acts as its own conductor.

Revised Wiring Diagram

Let me know what you think of this one (updated to include more info).

Good

I am adding a pic of a prior post.
I'll take apart vacuum this weekend for the wiring.
The two white are connected to switch so are the two black. I believe the orange is ground wire on the switch.
I'll double check but that's mmy guess.
