Distributors and Distributor Caps
Distributors and distributor caps are components of an ignition system. Most internal combustion engines use these to deliver high voltage sparks into the engine in the correct firing order, which in turn creates combustion.

How much does it cost to replace O ring in a distributor?
The o-ring is only about a dollar or so and the labor consists of removing the dist. cap, marking where the rotor is pointing as well as marking where the ditributor base is set. After marking reference points, remove the 15mm bolt that holds the dist. retainer in. Gently turn the distributor back and forth while pulling up at the same time.Once the dist. is removed the o-ring will either be under the distributor or around the round hole on the intake. Installation is the reverse of removal, just make sure to reference the marks to ensure proper realignment upon installation.
CAP is an acronym that stands for over 350 different things. Some of them are Center for American Progress, Civil Air Patrol, Client Assistance Program, and College of American Pathologists. Some additional meanings are Community Advisory Panel, Combat Air Patrol, Crimes Against Persons, and Creative Arts Program.
How does the ignition trigger work on a 2001 GMC Sierra with individual coils?
there are two main sensors used to do this a crank position and a cam position sensor. They tell the computer where the internal parts of the engine are in a 360 degree cycle and the computer tells coils to fire at the appropriate time

How do you get your 2001 Pontiac Aztec out of park while engine is running?
Put your foot on the brake. Most/all newer cars have an interlock that keeps you from shifting from park to drive without your foot on the brake. Sometimes if you park the car on a hill, it will be difficult to move the shifter out of park. That's why some people use the emergency brake before putting the car into park when parking on a hill or incline (like a driveway)
Could a faulty ignition coil lead to increased emissions?
If it's weak you might have incomplete combustion or possibly an irratic misfire, but most likely the problem that causes increased emissions is elsewhere. An increase in hydrocarbons is often caused by the O2 sensor or possibly the EGR valve. You could also have a problem with plugs, distributor, rotor or plug wires.
Why does the ignition wires on a F150 1998 with 4.6 go bad are they not heavy duty enough?
The wires are fine, they were engineered to handle the electrical load of normal operation. If the wires have overheated it's because something shorted out or someone connected the electrical wrong.
make sure the car isn't over heating. it can over heat without showing on the gauge or light. check your coolent fluid level, if it's ok make sure the thermostat is ok. have your heat sending unit replaced as it can be faulty also. another problem can be the computer putting it out of time when it is warmed up. have it checked as soon as possible because these small engines can't take much overheating.
Does a 2000 Chevy C2500 have a distributor?
Well that depends, the 2000 Chevy c2500 is the transition year, and depending on what parts were remaining, as to what percentage of the vehicle is made up with 1999 parts. My 2000 Chevy c2500 truck has a distributor, my friends does not. Unsure as to why, but they are the original engines in both vehicles. Best to open the hood and look to the rear of the engine, do the spark-plugs enter into a roundish plastic device with fingers sticking out four on each side and one out the top. That would be the distributor.
Every part of the computer control and injection system needs to be considered. For example, the fuel pump of an injected system runs at a much higher pressure than a carburated system. You'll need to work that out. You would need to work around the electronics for the ignition if you decide to use a HEI system and you'd probably need to do some rewiring of the keyswitch circuit as well as possibly some modifications to the gauges. Understand that most injector fuel pumps are also connected to the fuel gauge system. Whatever you THINK you've worked out, there will be additional concerns. But it can certainly be done. Converting the engine will probably be the easy part.
Where does number 1 plug into the distributor cap on a 1969 Chevy pick-up?
Hey Jerry==Since it is not new it is possible that it has been changed from factory. To find out where it is, if it is factory or not, pull #1 spark plug ,and the coil wire so it won't start, and stick your finger on the plug hole and have someone bump the starter to see when the piston comes up on compression stroke. When you feel preasure, turn the engine with the belts and pull the timing marks up to tdc. Pull the dist cap and where the rotor is pointing is #1 on the cap .the firing order is 1-8-4-3-6-5-7-2 and the dist turns clockwise. GoodluckJoe
Sounds like the bearings or bushings in your distributor are worn. With the cap off, check for any wobble or play on the shaft. If so replace the distributor.
Which position is number 1 on the distributor cap of a 1995 Chevy Z71 350?
#1 will be the first hole past the cap's mounting screw on the left side of the distributor, going clockwise.
What's the firing order for a 1970 Dodge Dart Swinger 318?
the firing order is 1-8-4-3-6-5-7-2 and the distriburator rotates counter clockwise.
What position should the plug on the distributor be in at TDC on a 4.3 Chevy?
The rotor inside the distributor should be pointing at the #1 spark plug.
A magneto is the earliest form of generator. When a magnet passes a coil, electrical current is created. A magneto creates a low voltage that gets sent to the secondary coil ,which is a large capacitor, this turns the low voltage to a very high voltage that then goes directly to the spark plug. Only electrically insensitive auxiliaries can be run with the electricity provided by a magneto (eg lights, some horns). With some circuitry, many more things can be run from a magneto.

The above answer is mixing two separate devices and describes the function of a 'magdyno' such as were commonly used on small engines.
A magneto is a device specifically used to generate the high voltage needed to fire a spark plug.
They were common on larger motorcycle engines of the past (pre-1960) and are still used on some aircraft engines.
Some people still prefer to use them on racing engines and souped up Harley-Davidson motors.
The magneto does use two sets of coils, the first producing the low energy current which is raised by the secondary high energy output coils, this pair of coils works as a transformer.
The magneto also uses mechanical switching through a set of points that open and close to fire the spark and the points or contact breakers also include a capacitor which is a device that stores electrical energy whose purpose is to prevent sparking at the points which would quickly cause them to become burnt and start to fail.
the magneto and alternator work in the same principle. the main difference is that in an altrnator, the the amrmature spins in a statinonary set of magnetic fields.,but, in a magneto, the amrature portion is stationary, and the fields are sets of PERMANENT magnents that spin around the core(armature), to produce electrical current...
On small or light aircraft such as a Cessna, there are TWO (2) magneto's and two sets of spark plugs in each cylinder. Each Magneto creates a spark for different plug in each cylinder therefore if one mag quits or failes the other one would still be firing one plug in all cylinders. One other note about magneto's, the left one is usually set to retard the timing for start. This is done through the use of an impulse coupling once the engine is at idle speed the impulse coupling will change the spark timing back to normal, usually around 25 deg before top dead center. Note usually only happens on one mag and is usually the left mag.
How do you know if your distributor is working?
YOUR CAR WILL RUN IF IT IS NOT YOUR CAR WILL NOT RUN!!!!! if you mean my car won't run and is it the distributor, please check to see if your plugs have spark. If not, then no it is not working. But, none the less if the distributor is shot, don't be a tight wad. The most expensive distributor cap I have ever seen was $28.00. However, the distrbutor shaft itself, if it isn't working, that means your motor has siezed.
IF your coil isn't working first check to see if its getting voltage. If it is replace the coil. If it isn't then you got a wiring problem. That could be caused by a number of problems. Note when checking a coil there are proper procedures for checking it. Basic simple test for checking it from a repair manual will help isolate the problem. Can't go into details not knowing the make and model of your car.
Does the distributor rotor have to face the number 1 plug wire on installation?
It has to face the same place it was when it was removed.
How do you test a pickup coil?
without more information regarding make, model and engine we are working on, it will be impossible to answer this question specifically, however, there is a generic answer that may help. A pick-up coil, technically known as a stator, provides a low-voltage digital on-off signal to the ignition control module where it is interpreted as an RPM signal, also called PIP or profile ignition pick-up. The ignition module uses that info to decide when to fire the ignition coil. This signal from the pick-up is most likely a ground signal, but I suppose some systems might switch the positive on and off. You will have to use a special low-voltage test light(a regular 12 volt test light will not do), find the signal output wire from the pick-up, and measure the output while the engine is being cranked. You should see an on-off pulse indicated by the light blinking on and off. Remember, this is providing the stator has it's power supply and ground needed to operate, and that the distributer is turning as needed while the engine is being cranked.
Where is the number one on the rotor cap?
# 1 piston is on the driver's side front plug. Turn the engine over until that piston is at top dead center, (TDC) on the compression stroke. Now look inside the distributor. The rotor will be pointing at #1. At about 11 o' clock on the distibutor. www.boxwrench.com NEW ANSWER: The first answer is right, and if the Distributor is in correctly when you
look stright down on the cap #1 will be at 5oclock on the cap.
look on your intake manifold each cyl.has a num.above it.near the frunt of the manifold is your fireing order.bring #1 to t.d.c.(top-dead-center)the rotor button is at #1.cap should be marked.
What kind of vehicle would a GMC Q-Jet carb by Carter come from?
not sure of all makes but they were widely used on 80-82 camaros and similar F-bodies (firebird etc) I have a 1977 Firebird I pulled my complete 350 engine from a 1978 Camaro and with it came a 4bbl Q-Jet by Carter. The owner of the camaro said that is what the car came with and it was all original. Hope that helps.
How do you test a lawn mower ignition coil?
Remove the kill wire from the ignition coil. It's the only wire that doesn't go to a plug. Remove one of the spark plugs. Reconnect the plug wire to the plug that has been removed. Make sure the threads of the plug are touching metal on the engine somewhere. Crank the engine. Should see spark.
If not, bad coil.
