    right. I took it to a motor repair place and they started the motor. They said it worked fine. I was happy figuring that when they took the back off maybe something had crossed the wires. The guy hooked up the green wire as ground and told me it worked ok. When I got home and hooked it back up to the switch i got fire out of the plug again. I called him back when he told me that they used the green for ground. I told him that the white wire is what i am having a problem with and when i put a ohm meter across it to the black it shows continuity betwee them both. He told me that there is supposed to be continuity as it runs thru the wire windings. That just doesnt seem right to me. When it is switched on the switch is running power to my ground making the sparks. The motor starts to start but my plug is on fire. I tried to take the back off where the wires go in but pretty unsuccessful.

    I am not sure if my response went thru. I took it to a repair place and they told me that the motor was working ok. I took it home and when i plugged it in the same thing happened ie sparks out of the plug. I called him back and was told that they used the green wire for the ground. The white wire has continuity wiht the black wire. Sending a direct short to the plug. He told me that there should be continuity between the black and the white. This just doesnt seem rightt to me. I tried to take the back of the motor off to see the configuration but cant seem to get theback off and dont want to break anything. This is a sears compressor. it is not on their recall list. I kind of need to confirm that there should not be continuity between the two wires. Then if you could advise how to get the back off. if i can tunk it with a hammer or what.

    somehow inside of the motor , the white wire is comming back hot. how do you get the back of the motor off?

    Green is gound always, black is 115 volts AC and white is common. That is about all I can do for you without being there to see what is going on.

I have a 12 inch chraftsman table saw with 2 wires coming from motor. The wiring diagram inside the cap shows it to be wired for 240 how do I wire that thru a switch and to a three wire recepticle

Not quite sure what your question is - Are you trying to plug a 240 into a 110/120 outlet? Or are you trying to plug this into a 240 3 prong outlet?

Traditionally, table saws don't come with a power cord - you must supply one. Usually on the motor there is a metal plate that describes volts/amps/phase/hp etc. Get the Volts/Amps from this plate, then measure the approximate distance between your table saw and the 240 outlet. The gauge of the power cord depends upon the Volt/Amps and the length of the cord. There are many volts/amps vs length for wire gauge conversions on the net. I always get a bigger wire (smaller gauge) than what is recommended. Expect to pay $100 or more for the cord (don't be cheap here). If you have an under rated cord, you can start a fire, burn up your motor, melt plugs into outlets and have to replace the outlet (don't ask how I know).

I'm a little suspicious of the "white and black" wire from 240 - it's usually "white and red" with a "black" ground. 240 is made from two 120's - opposite sine wave. So black is usually the common ground, while the white and red are the two 120's. Volts between white-red=240, white-black=120, red-black=120. If you're absolutely sure that white-black=240, then you can just connect a ground wire to the motor case. Many home table saws can be wired for 240 or 120 - you need to make sure that you're hooking 240v to the correct wires. If you're uncertain at all, then don't do it.

I have wired 120 to a 240 motor by accident and the motor ran - it had no power and didn't spin at full RPM. You can damage a motor this way, so I wouldn't recommend it. I have never put 240 to a 120 motor - so I don't know what happens (guessing you could burn up the motor coils).

With all that being said, if you have 240 outlet with 3 wire receptacle, then just use a multi-meter to determine the 2 "hot" and the 1 ground. Volts from hot1-hot2=240, hot1-ground=120, hot2-ground=120. If you don't have a multi-meter, buy one (approx $12). Once you have it wired up, then try the motor by flipping the switch on then off again. If the motor didn't spin, then you did something wrong. If it hummed but didn't spin, you have some connections wrong inside of the motor. If it spins the wrong way, then your wiring inside of the motor is wrong (doesn't help to flip the wires on the outlet). If you blew a circuit breaker, then the wiring to the motor is wrong.

Un plugged the wires from the switch and do not remember how it was wired up. I have three white wires and one black. One white and black wire is coming from the power cord the other two white wires are...

Mmmm... that's a little more complicated. If you have a continuity / resistance meter, we can noodle it out, though.

First, are the two white wires the ONLY wires coming from the motor? I suspect they are - that's not in conformance with any accepted color code, but it'll work. For the rest of this, I'll assume that the two white wires are the only ones from the motor.

You'll need to meter the switch itself, with no wires connected to it. In the OFF position, you shouldn't find continuity between any of the four switch contacts. In the ON position, you should find continuity between two pairs of contacts.

The black wire from the power cord should go to ONE of the two switch contacts in a pair that have continuity with the switch turned ON. One (either) of the white wires from the motor should go to the other switch contact IN THAT PAIR.

That leaves you with one more pair that has continuity with the switch turned ON. The white wire from the power cord goes to one of those, and the second white wire from the motor goes to the other one.

When you have it all wired up, plug it in & turn it on. If it's not right, it should immediately pop your circuit breaker. If it IS right, it should run fine.

If it pops your circuit breaker, open it back up and swap one wire from the power cord and one wire from the motor.

Proper wire hook up

black goes to L1 white goes to L2 make sure to look on side of motor to change from 220 volt to 110 volt either a knob or changing wires brown and white to different locations hope you didnt fry motor

Hi I have a 691 and want to outlet on all the time and the switch to control a light. Your diagram show black wires on one side and the white wires on the other side. Shouldn't a black wire be on one of...

If your switch is wired internally so the switch automatically controls the plug, then there is not a way to re-wire the insides of that device.

Look at the screws on your device.
If switch automatically controls the plug, there are probably gold-colored screws on one side of device and silver-colored screws on other side of device.
The blacks connect to gold, the whites to silver

If this is how your device looks, then the switch cannot control a light, so buy a device that looks like the one described next:

If the plug and switch can be wired separately, then the screws are different colors
1) On one side are dark-colored screws. The Hot wire from breaker box always connects to dark-colored screw.
2) On the other side of the device are 1 gold-colored screw and 1 silver-colored screw
- The white wire connects to silver screw and this will complete the circuit to the plug
- The wire going to your Load (light, fan motor) connects to gold-colored screw, and this will let the switch control power to the Load

You can buy a simple continuity tester and check your wiring devices before purchase:
Continuity tester is used when power is turned off.
It has a battery
When you youch alligator clip to the tester point on end of tester, a light comes on.
When light comes on, that tells you the circuit is complete
For testing switches and plugs, you touch the pointer on one screw terminal, you touch the clip to another screw terminal ... then flip the switch on the electrical device to see which screw terminals cause the tester light to come on
If light comes on, then the circuit has 'continuity'
Continuity tester can be used on all sorts of small electrical devices, including troubleshooting electric water heater >>> and that's a fun project for next week.

Do not know where to connect hour meter wire to the spark plug

One wire is the flexible silicone rubber wire from the spark plug to the ignition coil. You don't have to strip or connect the other wire, just wrap it around the spark plug wire a few turns.The current from the spark ignition will induce a signal into the hour meter that the meter uses to determine when the motor is on or off. I hope this helps and good luck.1b05a64.jpg

I am replacing the a/c blower motor and capacitor. The old motor has 1 brown wire to the capacitor, 1 yellow wire to the capacitor (the yellow then loops from the capacitor over to the wiring panel), 1...

Motor Wiring
Old Motor
Brown wire is Start
Yellow wire is run or Power
Black wire is High Speed or Common
The other two taps are speed taps, but you have a single speed application
And high speed is what you need ,that’s why there’s not any wires
on Red and Blue if high speed was to much then you would move the
Black wire to one of the other taps RED low speed or Blue Medinm speed
New Motor
White goes to the Yellow wire from the capacitor
Black goes to the Black wire you took off of high speed on old motor
Of course both Brown wires go to the capacitor and Green to ground
If a capacitor doesn’t discharge it doesn’t mean it’s bad
but the capacitors don’t last as long as they used.
Any time you put in a new motor always replace the capacitor
It will save you a lot of time and grief later on.
