Hook up timing gun

Not all your car issues need to be dealt with by a mechanic. Sometimes, the problem could be as mundane as a simple off timing of your ignition. Crazy enough, many people are unaware of how straightforward it is to set the ignition; a job that lacks the help of a mechanic. Setting the ignition timing does not require any advanced knowledge of automotive repair, it simply requires one vital equipment; a highly efficient timing light. No doubt, the quest to find the perfect timing light from the hundreds available on the market can be challenging, but we have good news for you.

The Best Timing Lights (Review) in 2019

It doesn't exactly inspire confidence when you're driving along and feel a sudden succession of shudders and thumps emanating from your car engine. Knocking , as the condition is known, could be a sign of something dire What do you do? Well, you could take your car down to Honest Al's Auto Repair and fork over the dollar-equivalent of a nice evening out for two Or, if you have an older model car that uses a distributor, you could diagnose the problem on your own using a timing light.

Simply put, a timing light helps to fine tune when the spark fires from the spark plug and ignites your car's fuel. Properly adjusted timing, in turn, helps to make sure your engine works at peak power and efficiency. And who doesn't want that? First, you should know that timing lights come in a few different shapes and sizes, and range in features from bare-bones functionality to lots of bells and whistles.

The simplest and least expensive timing lights fit into a basic pen shape. But most people would probably prefer the much cooler, ray gun-shaped, "pistol grip" variety More importantly, the more expensive the timing light is, the more likely it will be easier to read even in bright conditions. This information, by the way, applies to mostly older vehicles, which use a distributor to send electrical energy to the spark plugs. Newer cars with distributorless ignition systems use a computer to control the ignition process.

One cool thing about timing lights is that unlike a flashlight, you never have to worry about running out of juice to power the light. That is, as long as your car runs and is connected to a working volt battery. Getting your timing light ready for action is breathtakingly simple. With the engine off, you merely clamp the timing light's red wire to the battery's positive terminal, then the black wire to the battery's negative terminal. Lastly, you take the signal wire and clamp it directly to the Number 1 spark plug wire.

If you're not sure which is the "Number 1" spark plug wire, stop! And get thee to a service manual or online owners' forum for your vehicle. With a few of the timing lights out there, you might have to attach the unit's spark signal pick-up wire directly to the spark plug tip. Most light units on the market today, however, clip right to the spark plug wire itself. These inductive timing lights are able to detect the jolt of electricity each time the spark plug fires, similar to a doctor using a stethoscope to determine your body's pulse.

When you pull the trigger of the timing light with the engine running , each time the Number 1 plug fires, the timing light flashes a beam of light. Through a phenomenon known as the stroboscopic effect, a properly aimed timing light will indicate where the Number 1 piston is in its up-and-down travel when the spark fires. Representatively speaking, that is.

Obviously, you don't see the actual piston's location. Instead, the timing of the spark is measured in terms of degrees. The degrees refer to how far the crankshaft has rotated relative to the Number 1 cylinder's piston at top dead center TDC of the compression stroke. On some vehicles, the crankshaft pulley has a bunch of degree marks and numbers on it.

The engine has a mark right next to the pulley that represents TDC. The strobing timing light "freezes" the motion of the pulley and allows you to see how many degrees before or after TDC the spark is firing. By manipulating the distributor cap turning it slightly clockwise or counterclockwise , you can adjust that timing of the spark delivery. To make things more confusing: Sometimes the timing marks are found on the flywheel or even on the fan pulley.

And sometimes the indicators are reversed. So just read your vehicle's manual and know what you're looking for before you start waving that light gun around! For any number of reasons, a person might wish the spark to fire earlier than the piston reaching TDC this means the timing is advanced. Conversely, if excessive knocking is a problem, it might seem a better idea to have the spark ignite the fuel slightly after the piston reaches TDC this means the timing is retarded. How do you know what the proper timing specifications are?

You can easily find that on your Vehicle Emission Control Information Label located on the underside of the hood or along a fender well for vehicles built in the United States or in a service manual specific to your vehicle. These are generalized instructions for how timing and a timing light works. Depending on the quirks of your vehicle and which timing light you use, what you actually see under the hood may differ. You can use more advanced procedures for instance, adjusting the vacuum timing to wring even more finely tuned performance out of your vehicle.

Regardless, the best thing to do is read the specific instructions in your vehicle's service manual, and the directions that came with the model of timing light you use. Also, remember that any aftermarket equipment you install, like non-standard spark plugs or spark plug wires, could result in inaccurate readings. How to Static Time an Engine.

The car's timing refers to the ignition and the process by which the spark plugs fire, creating a spark in the car's combustion chamber. Your timing must be at the correct setting for your car to perform at top level, affecting the speed and efficiency at which the engine fires. You can adjust your car's timing with a timing light and a set of wrenches, tools available at any auto parts store.

You need to adjust timing on a car for many older models those which have a distributor to maintain the best possible performance.

Timing lights are a diagnostic tool used on cars without computer-controlled ignition to help the mechanic find the correct setting for ignition timing. Proper timing on a car improves fuel mileage, engine longevity and performance. The device resembles a gun with a flat front and three wires hanging from it. These are connected to the battery and spark plug wire prior to use.

If you notice your vehicle running rough or you just want to perform a regular tune-up, an advance timing light comes in handy. Any spark-ignited engine needs proper timing to ensure fuel economy and performance. An advance timing light is therefore a necessary tool every technician and do-it-yourself mechanic should own. Of course, simply owning an advance timing light is not enough. You must understand how to prepare your engine, connect and read the advance timing light, and adjust the timing. Fortunately, all of these steps are relatively easy to carry out with the help of just a few basic instructions. To prepare the engine for timing, you must follow the instructions on the Vehicle Emissions Control label. Find this label underneath the hood, though in some vehicles, it might be on a valve cover, in a fender well, or near the hood latch. If you cannot locate the label, consult the vehicle manual. This is important because preparation is specific to each engine.

How to Use an Advance Timing Light

A timing light is a stroboscope used to dynamically set the ignition timing of an Otto cycle or similar internal combustion engine equipped with a distributor. Modern electronically controlled passenger vehicle engines require use of a scan tool to display ignition timing. The timing light is connected to the ignition circuit and used to illuminate the timing marks on the engine's crankshaft pulley or flywheel , with the engine running. The apparent position of the marks, frozen by the stroboscopic effect , indicates the current timing of the spark in relation to piston position. A reference pointer is attached to the flywheel housing or other fixed point, and an engraved scale gives the offset between the spark time and the top dead centre position of the piston in the cylinder. The distributor can be rotated slightly until the reference pointer aligns with the specified point on the timing scale. Fuel-injected engines, or engines with microprocessor controls may require special procedures to allow basic spark timing to be observed without control effects from the engine computer.
