Re: need the wiring diagram for this vacuum electrolux
Open the door to remove the bag. Pull the side bumpers forward when the door is open. The profile of the edge of the top and the bottom of the vacum body is a "L" shape. The cross section of the bumper is a "I" and that holds the body together. Carefully lift up the top just a little to free the plastic end cap that conceals the cord spool. There are two plastic pins on the top and bottom that hold this piece on and they frequently get broken. (If that happens repair shops drill and hole and insert a screw.)There is a plastic protector plate that lifts up on either end and then is slid about 1/8th inch clockwise and then up. Copy the wiring pattern on the four male connectors on the motor and the wire spool.

Your top motor (suction motor) isn't running. Your vacuum has two motors in it. The top motor is the suction motor that runs on the first switch position and the bottom motor (brush motor) turns on with the second possition.
It could be the switch.If it isn't the switch, the only other thing it could be is the motor itself.
To check the switch, unplug the vacuum and then take the three screws out of the back of the handle. If you are comfortable with electricity, jump the black wire and the blue wire togeather and plug the vacuum into a electrical outlet. If the motor dosen't run, the problem is with the motor. If the motor runs, the switch is bad and needs to be replaced. You can get one at most any vacuum shop.
The motor could be bad or the carbon brushes can be stuck with dust. This is more involved and I recomend taking the vacuum to a vac shop that works on the "old" Electrolux vacuums. The new name for the "old" Electrolux is now Aerus Lux but you would probably get it repaired less expensively at another vacuum shop.
If you want to go into the motor housing you'll have to take the big screw out of the back of the handle and pull up on the handle to remove it. Next, remove the four screws holding the top half (motor housing) of the vacuum. Two screws on the back and two screws to the front inside of the bag housing. You'll need a long #2 phillips screw driver. Then pull up on the bag housing with a side to side motion.
With the housing removed, you will see the motor and can lift it out.
Check for any bad winding. You can smell them to check if you can't tell by looking at them. If they are burned, you will need to replace the motor.
To check the brushes, you will need a 5/16th" socket to remove the two bolts on the top of the motor and lift the top bracket with the carbon brushes off and see if the brushes move freely. If not moving or not long enough to touch the top part of the motor with the copper bars (the comutator) it would be best to replace the motor.
To reassemble the vac just reverse.
This is a long and difficult prosedure and I reccomend that you take the vacuum to a repair shop that works on the Electrolux.
Unfortunaly I don't have that wiring diagram. I am sure that the service manual can be ordred thru sears as they are the carriers for this material. What excactly is the issue and maybe we won't need the diagram.
To test the vacuum motor and circuit card, detach low voltage wires from vacuum. Using insulated needle-nose pliers, place points of pliers in each wiring connector. This should start and run the motor as long as the pliers are in place. If it does, the problem is elsewhere, If the motor doesn't run, either the motor, circuit board, or internal wiring is bad. It needs to be taken to an authorized Aerus Electrolux store for repair/s.
If the motor runs, the problem exists in the hose and attachments. Broken wiring, switches, and worn or loose wand connections could be the problem. If you are unable to test the hose and wiring for continuity, take the whole machine to the nearest Aerus Electrolux store for a free diagnosis.
Check all the wiring connections to make sure they're tight.
1/2. Wiring to power nozzle motor or reset switch is loose.
1. Cord from power nozzle to upper wand. If the plastic portion of the wand is cracked near the cord connection, or the connections are blackened, they need replaced.
2. Wiring connection from hose handle to upper wand. Check for cracks and discoloration as in 1 above. Replace if necessary.
3. Hose connection to vacuum. Not likely, but possible.
4. There could very well be a break in the hose wiring.
You may need to take your vacuum, with hose and power nozzle, to an authorized Aerus Electrux service shop. They can try a new hoze to see if that's the problem. If there is a break in the wiring, the hose is probably worn in other areas as well, and should be replaced.
You won't find a diagram. You will have series of yellow and white and sometimes gray wires on the outside of the motor housing and often a letter code etched on the housing , indicating the original wiring from years ago, red, blue, yellow, however the newer wiring eliminated those colors. These wires are almost fool proof as they will align with the longest wire at the furthest point,a center one piggy backed , etc however before starting please post back to advise if you have removed the rewind and or motor and if so, did you disturb the motor wiring inside the motor shroud. Please post the original problem you opened the vac for as well and I will try to walk you through this

Post your wiring diagram and it will solve a lot of people's problem trying to reassemble this machine's -- including mine.
