Harley-Davidson Motor Company has released a new dial back timing light (PN diode 31395-02). This new light has been designed to make it easier to find the correct timing point when performing a service on a Harley-Davidson motorcycle. The light has been approved by the Harley-Davidson Motor Company and riders are encouraged to use it.
Here are the steps for using the new dial back timing light:
1. Connect the negative (black) lead from the light to the engine ground.
2. Connect the positive (red) lead from the light to the number one spark plug wire.
3. Insert the light into the spark plug hole.
4. Make sure that the light is in the center of the spark plug hole. If it is not, it will give a false reading.
5. Slowly turn the engine until the pointer on the light points to the correct timing mark.
6. Remove the light and restore the spark plug wire to its original position.
The new dial back timing light makes it easier to find the correct timing point on a Harley-Davidson motorcycle. Follow the steps above and you will be sure to get the correct timing.
How do you connect a dial back timing light?
First, you need to remove the spark plug wire from the spark plug. Next, you need to remove the distributor cap and rotor. Once you have access to the distributor, you need to find the correct timing mark on the crankshaft pulley. Once you have found the timing mark, you need to connect the dial back timing light to the spark plug wire. Once the timing light is connected, you need to start the engine and let it idle. When the timing light flashes, you need to note the reading on the dial. The next step is to adjust the distributor so that the timing mark is aligned with the correct reading on the dial. Finally, you need to replace the distributor cap and rotor, and reconnect the spark plug wire.
How do you set the dial back timing light?
To set the dial on a timing light, first find the timing mark on the engine. This will be a notch or embossment on the crankshaft pulley or timing cover. The timing mark will correspond to a line or arrow on the timing light itself.
Once the mark is located, align the pointer on the timing light with the mark. To do this, loosen the light's clamp and rotate the light until the pointer is lined up. Then, re-tighten the clamp.
Now that the pointer is lined up, you can read the number next to it. This number is the amount of degrees before or after Top Dead Center (TDC) that the timing mark is.
From here, you can adjust the timing by rotating the distributor. If the timing is too far advanced, rotate the distributor counter-clockwise. If the timing is too far retarded, rotate the distributor clockwise. Each rotation of the distributor should advance or retard the timing by about 2 degrees.
Once the desired timing is set, recheck it with the timing light to be sure.

Using a Dial Back Timing Light
A dial back timing light is a specialized timing light that is used to check the ignition timing on an engine. It is different from a regular timing light in that it has a dial that can be used to adjust the timing. This makes it possible to set the timing accurately without having to remove the timing cover from the engine.
The first thing you need to do is to find the number one cylinder. This is the cylinder where the piston is at the top of the stroke when the engine is at TDC (top dead center). The easiest way to find the number one cylinder is to look for the cylinder that has the spark plug wire going to the number one spark plug.
Once you have found the number one cylinder, you need to find the timing mark on the crank pulley. This is usually a white or yellow mark that is located on the edge of the pulley. Once you have found the timing mark, you need to attach the timing light to the number one spark plug wire.
Once the timing light is attached, you need to start the engine and point the light at the timing mark. The timing mark will appear to move as the engine is running. You need to dial the timing light back until the timing mark is at the top of the pulley. This will give you the correct ignition timing.
What are the benefits of using a dial back timing light?
There are numerous benefits to using a dial back timing light. Perhaps the most useful feature of a dial back timing light is that it allows the user to check the timing without having to disconnect any wires. This is a big time saver, as it eliminates the need to remove and then reinstall the distributor cap. Additionally, a dial back timing light is very accurate, which is essential when setting the timing on an engine.
Another big benefit of using a dial back timing light is that it is much easier to use than a standard timing light. With a standard timing light, the user has to hold down a button while looking at the timing marks on the engine, which can be difficult to do while also paying attention to the engine itself. With a dial back timing light, the user simply has to hold the light in place and then turn the dial to the desired setting. This is a much simpler process, and it allows the user to keep both hands free, which is important when working on an engine.
Finally, dial back timing lights are relatively inexpensive, which makes them a great option for budget-minded mechanics. They are also widely available, so they can be easily found at most auto parts stores.
How does a dial back timing light work?
A timing light is a type of light which is used to measure how fast something is moving. It is usually used to measure the speed of an engine's crankshaft. Timing lights usually have a long, thin body and a small, bright light at one end.
To use a timing light, the engine's ignition must be turned on and the engine must be running. The timing light is then connected to the engine's spark plug wire. The timing light is turned on and the light is shone on the engine's crankshaft pulley. The timing light will flash at a rate which is proportional to the speed of the crankshaft.
The timing light can be used to adjust the ignition timing of an engine. If the engine is running too slowly, the timing light will show that the spark plug is firing too early. This can be corrected by advancing the ignition timing. If the engine is running too quickly, the timing light will show that the spark plug is firing too late. This can be corrected by retarded the ignition timing.
Is a dial back timing light accurate?
A timing light is a device used to measure the speed of an engine's crankshaft rotation. The accuracy of a timing light is critical for tuning an engine for optimal performance.There are many factors that can affect the accuracy of a timing light, including the quality of the light itself, the condition of the engine, and the operator's experience.
The quality of the light is the most important factor in determining the accuracy of a timing light. A high-quality light will produce a bright, consistent light that will allow the operator to easily see the timing marks on the engine. A poor-quality light will produce a dim, flickering light that will make it difficult to see the timing marks.
The condition of the engine also affects the accuracy of a timing light. An engine that is in good condition will produce consistent timing results. An engine that is in poor condition will produce erratic timing results.
The operator's experience is also a factor in determining the accuracy of a timing light. An experienced operator will know how to properly use a timing light and will be able to avoid common mistakes that can lead to inaccurate results. A inexperienced operator may not know how to properly use a timing light and may make mistakes that lead to inaccurate results.
In conclusion, the accuracy of a timing light is critical for tuning an engine for optimal performance. There are many factors that can affect the accuracy of a timing light, but the most important factor is the quality of the light itself.
How often should you use a dial back timing light?
A timing light is a tool that helps you measure the speed of your engine's rotation. It's important to keep an eye on your engine's speed because it can affect many aspects of your car, including fuel efficiency and emissions. Too much speed can cause your engine to wear out quickly, or even overheat.
The best way to use a timing light is to first find the TDC mark on your engine. This is the Top Dead Center, and is usually marked with a white dot or line. Once you've found TDC, attach the timing light to the number one spark plug wire. Make sure the light is pointing in a safe direction, away from you and any other people or objects.
Now, start the engine and let it idle. The timing light will flash when the spark plug fires, so you'll be able to see the engine's speed. If the light is flashing too quickly, that means the engine is going too fast. If the light is flashing too slowly, that means the engine is going too slow. If the light is flashing at a steady rate, that means the engine is going at the correct speed.
So, how often should you use a timing light? It's a good idea to check the engine's speed every time you get an oil change. That way, you can keep an eye on any changes in the engine's speed over time.
How long does a dial back timing light last?
A dial back timing light is a tool that is used to help adjust the timing on an engine. The light itself is very durable and can last for many years with proper care and storage. However, the batteries that power the light will eventually need to be replaced. Depending on how often the light is used, the batteries may need to be replaced every few months or every few years.
What are the disadvantages of using a dial back timing light?
Whether you are a professional mechanic or a do-it-yourself car owner, you need a reliable timing light to ensure that your engine is running properly. A timing light is a diagnostic tool that allows you to see whether an engine's timing is advanced or retarded.
There are two types of timing lights available on the market: incandescent and LED. LED timing lights are the newer technology and are becoming increasingly popular due to their many advantages over incandescent lights. However, LED timing lights also have some disadvantages that you should be aware of before you make your purchase.
One of the biggest disadvantages of using an LED timing light is that they are not as accurate as incandescent lights. This is due to the fact that LED lights flicker at a much higher frequency than incandescent lights. This high frequency can cause the timing light to read the engine's timing incorrectly.
Another disadvantage of using an LED timing light is that they are not as bright as incandescent lights. This can make it difficult to see the timing marks on the engine when you are using the light.
Finally, LED timing lights are more expensive than incandescent lights. If you are on a budget, you may want to stick with an incandescent light.
Overall, LED timing lights have some advantages and disadvantages that you should consider before you make your purchase. If accuracy and brightness are important to you, then you may want to stick with an incandescent light. However, if you are looking for a more budget-friendly option, then an LED light may be the better choice.
Frequently Asked Questions
How do dial-back timing lights work?
Dial-back timing lights use the same principle as a car’s odometer. When you rev the engine, the dial on the back of the light rotates and brings the timing mark up to aligned with the 0 position on the tab. This tells you how much advance you have left in your engine.
What does the dial back light on a tach mean?
The dial back light on our tach indicates engine rpm and timing. On an electronic dial-back light like the one we're using, you use buttons to advance or retard timing. The digital display on our light will indicate amount of timing and engine rpm.
How to use a timing light?
When timing your engine, use a timing light to help you see the downward motion of the piston and the corresponding number on the timing tape. Look for the zero on the timing tape; this indicates the starting point of the upward motion of the piston. Move the light vertically along the tape in time with the sounds from your engine. The higher reading on the timer corresponds to a lower sound from your engine, and vice versa.
How do you dial back timing on a lawn mower?
The dial back light is a very handy tool when it comes to adjusting timing on your lawn mower. By using the light, you can easily determine which way the timing needs to be moved on the balancer in order to prevent any backward positioning.
How do you use a dial back light?
The easiest way to use a dial-back light is by revving the engine to maximum advance and lining up the TDC mark with 0 (zero) timing on the tab. The dial on the light then indicates the total amount of advance.
