Lovin' on the Avocado Bomber tonight. Hinge repair plans A and B both failed so we have a temp plan C in place for now. Don't ask, it's embarrassing.

The motor is rebuilt. To pass it through the opening in the bottom housing you have to remove one of the brushes. When I did so the carbon brush shot out of it's holder along with the spring. There is a copper braided wire that trailed out behind the carbon brush. I don't know if that wire is supposed to attach to anything or not. I put the spring and brush back into the holder making sure the wire was inside the spring, but how it makes contact other than through the spring is beyond me. I hope it isn't broken now.

Once the motor was screwed in the next mystery will be wiring. The motor has five wires, red, blue, black, white and yellow. In person, both the white and yellow wires look the same. I rubbed on them with some acetone hoping to draw some color out of them, but in person it is very hard to tell which is which. Imagine my surprise when looking at the images the white and yellow wires stand out clearly. Weird.

Tomorrow I have to solder wires to the On/On DPDT switch, including a jumper that connects two end terminals diagonally across the switch. High and low speed switching is accomplished by switching between parallel and series operation through this switch. Lamb has a diagram showing how to wire the switch and there is a barely readable wiring diagram sticker in the motor compartment, a small piece of which I found elsewhere in the vacuum and taped back into place. I hope I get this thing wired right!

Stay tuned kids. Include are images of hinge Plan A (failed, wouldn't take the necessary shape to clear that big white lid gasket) and another image of restoration staff taking a break. Come to think of it, all they ever do is take a break, unless they are redecorating something.

Braided brush lead

 Ideally, this should connect with the wire to the brush holder, but looking at your photographs, it looks like connection will probably be adequate without it. On photo#4 one brush holder appears to be the 'black' lead, the other is probably internally wired to one end of one of the field windings.

I have a feeling that I once saw an old Hammond Organ with a very similar shape of hinge. no idea of the model number, though :-(

All best

I will have to call the gent who rebuilt the motor and ask. He was telling me that the brushes he receives have been defective lately, not enough clearance between the metal inner housing and the commutator so he has to disassemble them and tap the metal inner housing back so nothing touches. I hope this is just an artifact of that process, but it was certainly a surprise. I have removed brushes for inspection countless times and never had one shoot the carbon brush across the table like that, sproing, hey come back here!

I have another newer two speed Kenmore I am going to take apart today to use as my wiring diagram for the Avocado Bomber. I have been saving it's spa day for this purpose.

More to come kids, I have a busy day ahead at the Kenmore High Desert Restoration Center.

Bravo, D.T! I got the photos on my desk this morning, Mrs.Sweep (The Kenmore southern-states restoration center's secretary, Mrs.Betty Super-Sweep, has been with us since day one!) Saw this and printed me a copy. Isn't she grand? Anyhow, that slightly-lighter color is neutral! my Duo-Power was like that too, I wonder if the =wires came from from the factory like that, or if they faded over time? They likely fade, but I guess we won't know until somebody opens a NIB Kenmore! laughing

 

If you ever need it, D.T, I'll gladly pop the cover off the Avocado Bomber's Floridian cousin for help! laughingwink

Oh, and speaking of,I was just using the Duo-Power yesterday! The power-nozzle saw a grand tour, and the new chrome wands got to clean the floor! The Duo-Power was happily puttering along the whole way! laughing

Keep your A-B together. I just took apart another Kenmore with a two speed motor today (see my other post) and documented where every wire goes with great care. The one I worked on today fired up with no problems so I feel pretty comfortable with the wiring of a five wire two speed motor. What a weird wiring scheme. The black wire comes right off a brush straight to the on/off switch. It is not attached to a field at all.

I am on the brink of popping for new paint for this vac. I look at it and the old paint has so much damage. When it's Powermate died in 1983 it was condemned to the garage, replaced by new and shiny, where it knocked around for three decades before I rescued it and it's by then not so new and shiny replacement. I will have to drive to Palmdale to have the paint color matched and a pint mixed. I guess I'll have to shoot it with an airbrush. It's too small a job for a body shop.

If I have time tomorrow I'll wire it up and test it, but I have two motorcycles that need some attention too. My 30 year old BMW K100RS has a leaky fork seal (easy fix if I can find the spare seals I think I have squirreled away somewhere) and my '07 Street Rod has a high idle I need to troubleshoot. Those are my basic day to day transportation so they are a priority. Afterwards I can fool with vacuums again.

I know it sounds silly, but.............

once, when I taught music, I gave a quiz. I asked about the black keys and the white keys on a piano (identifying them). One the picture I provided, some smart a## labeled, with an arrow, "These are the white keys, and these... another arrow, are the black keys. Of course, I meant sharps,flats, and naturals. But.... I "asked"..... That came to me when I saw "which is the yellow".. Sorry... HAD to.....

The photos are misleading, or maybe I am slowly going color blind, but in person, sitting in front of me on my table, both wires look yellow. I rubbed on both of them for quite s bit of time with acetone soaked paper towels hoping to bring some obvious, unambiguous color out of at least one of them. To my eyes in my home, neither looked clearly yellow or white. You have to understand my surprise to look at the images I took on my pc and, lo and behold, one wire is clearly white and the other clearly yellow. Even now with the actual motor in front of me it isn't as obvious as it is in the photos. I guess it is something in how the CCD imager in the camera interprets different wavelengths of light impinging upon the elements. That is the only explanation I can offer.

Poor D.T, I can only imagine the pain of seeing Kenmores in black-and-white FOREVER! Don't worry, I'll quiz you! Is the below Duo-Power.....

 

A: forest green

B: mint green

C: light grey

D: BLUE

E: avocado

Avocado of course!

Yours is the good plastic body, the last generation of the square, straight hose Kenmore canisters. I have it's cream colored counterpart, minus the correct tool garden for the lid. My Avocado Bomber is the prior gen with a steel lower body and flexomatic plastic lid. Yours, if you look, either has a big filter element that touches the underside of the lid as a support, or if it has the circular filter element there is a support structure right behind the bag that keeps the lid from being sucked inwards like my older machine suffers from. No bouncing tools on your vac!

Wait until I finagle a central vacuum motor into one of those, heh, heh, heh. I'll have to change my handle to Suctioncentral or something.
