If it came off of the coil, there is a 1/8" tap the wire end connects to.

No spark? Anywhere to check?

Check inside the distributor for loose wire connections, and signal from igniter.

Foot pedal won't stop from automatically running

Your foot pedal, it's like 98% of the rest of them, has a small swing arm that moves back and forth across a line of several metal buttons imbedded into a circuit board. Those small buttons have little prongs that fit through the circuit board material and connect to a small river of solder, so to speak, that in turn is connected to coils of wire. There are many of these small rivers of solder side by side and all connect to different wire coils. The wire coils all have different degrees of resistance to push the electricity on it's way to the main wire that will lead it back out to the wall outlet. Each time you push or let up on the pedal, that little swing arm goes back and forth across those buttons until you stop the pedal, and where you stop the pedal determines the speed at which the sewing machine runs. However, as the arm is traveling across the buttons it makes a small spark as it leaves one and approached the next one, EVERY SINGLE TIME IT MOVES from one to another, there's a spark. Sometimes if the electric service to your home is running on the high side of the 110V - 120V levels it can leave a small, minute, little tail from the arm and it's possible that the arm could become sort of welded, for want of a better word, to one or the other of the buttons, which would make the machine continue to run even after you've released the pressure on the pedal.. If it's plastic you could attempt to dislodge the arm by gripping the pedal with your hand and manually lift and depress it several times. If that doesn't jolt things loose and stop the running you need to either take it to a small repair shop or just buy a new one.

The outside unit, Goodman, clicks on and off when I turn it on. Sometimes it will run for a while then begin to click on and off. This happens when the fan is in either to auto or off position. It almost...

That could be a loose connection on the small low voltage wires which connect to the 24 volt coil under the contactor . OR the coil might be going bad. Or a critter could have chewed the small wires up or their could be older wires shorted going out there to the outside unit. It may well be the wall thermostat has stuff in it causing the problem.

I have a 1979 xlh sporty took bike apart to paint on re assembly i hooked up coil wires wrong had no spark fixed wires but could i have killed my coil still no spark.

Ok to test the coil, remove all wires from the small terminals on the ends. Use a digital volt ohm meter and put the function switch in OHMS, R X 1. Touch one meter lead to each of the small terminals. Your meter should read between 2-3 ohms as the '79 model had electronic ignition.

To further test the coil, reconnect the two white wires to one of the small terminals. On the other side, make a jumper wire. Connect the jumper wire to the other small terminal. Put the plug wires into the towers and put a set of spark plugs in the wires lying on the heads with a good ground. Now, turn the switch one. The terminals with the white wires on it should be "Hot". MOMENTARILY, ground the jumper to the engine and take it back loose. When you take the wire loose, you should see a spark at the plugs. If you do, the coil is good and your problem lies elsewhere.

Good Luck

Motorcycle cuts out and backfires when accelerating. black smoke puffs out when backfiring

I need more information. Is the bike carburated or fuel injected? Did it just start this or has it been doing this for a while? It sounds like either an ignition or a fuel problem.

If it has a carb, I'd say that it's jetted way too rich or the main jet has come loose in the carb maybe. Tell me what kind of carb is on the bike if it is indeed carburated. I need the year model of the bike and the name of the carb on it. Maybe I can tell you how it's supposed to be jetted. If the main jet has come loose, you will lose control of the amount of fuel going into the engine at wide open throttle.

You may have a bad spark plug as well, either get a new set or have the ones you're running now cleaned. When you pull them out, look and see if they're really black and sooty looking. This is indicating a rich mixture. Check your spark plug wires and make sure they're in the coil correctly. Check of loose connections at the coil primary (small wire connections) connectors. Make sure that chrome cover over the coil is not loose shorting out the ignition.

Fuel injected, I can't help you with that as it takes a special device to make any adjustment in that system.

I am not getting any spark

You will need a digital multimeter for easy reading ( The one I use cost $5 ). Find the connecter for the two wires for the on/off switch. Disconnect the wires and connect the meter leads to these terminals. Set the meter to Ohms and check that the switch opens and closes connection. Should read OL when open and .01 when closed depending on meter setting. If it checks out, then not the switch. Also check the coil and spark plug boot/wire with Ohm meter. Be sure that the boot is firmly connected to the wire. Small wire to frame- OL. Small wire to spark plug boot- thousands of Ohms (possibly 5000-30000 but don't know the spec). If either of these shows a small number of ohms (example: .01-7 ohms), then there is a short in the coil. Also check that the steel bar of the coil is grounded to the frame/engine with Ohm meter- 0.01. To test the source coil connect ohm meter to small wire coming out and other meter lead to engine ground- should be hundreds of ohms. Sometimes it is easier to start replacing at the least expensive part!

No spark on my 1985 cr250r

Start by...try another plug?
see that the coil wire that goes to the plug is clean, and not damaged or torn. If you have a kill switch, unplug it. (The harness usually has connectors about a foot and a half away from the switch)

Airforce 12000BTU Air Conditioner wiring problem

The outdoor unit should have 2 small wires connected to the contactor coil. This delivers the 24v "Signal" to energize the coil. The wire from the t'stat for cooling are usually yellow, in almost every case. When you put the t'stat in the cooling mode and set the temp lower than the room temp, the indoor and outdoor unit should come on. Check for voltage on the terminal block for 24 volts accross the yellow and common wire. Common could be ground on some handlers. If you have the 24 volts, then check for 24v on the 2 small wires (usually 18 to 22 gage wire) on the contactor coil. If no voltage, trace the 2 wires back to the indoor unit and see where they go. If they are the ones that are not attached, put one on the yellow wire terminal and the other on the common terminal. This will send power to the indoor unit and then piggyback to the outdoor unit. Do not remove the yellow and common from the terminal block. Don't be too concerned about the colors from the outdoor coil wires. Just make sure they are hooked up right. Good Luck and hope this gets it going.

No fire to one of the coils which supplies 2 plugs engine light on and running on 4 of 6 cly.

Several possibilities. Internal coil failure, wiring or connection problem, computer is not functioning properly to energize the coil pack. Which two cylinders? I gather the Check Engine light scan reveals misfire codes (DTC) P030? and P030?
Check out the wiring diagram:
dde5042.jpg 78bd4d6.jpg Problem could be here or at the ECM connection. If not, then the coil pack has gone bad.

Hi, I was wandering if someone could tell me, what i need to do to fix my piaggio liberty 125, it has no spark. I have installed a new spark plug and still no spark.

Try removing the distributor cap and ceck to see if the rotor was broken. Please bear in mind this might not be the problem, but it's a start.
