How do you check timing with timing light?
Take your timing light and aim it at the timing marks, pressing the button on the light. Because you have the light hooked up to your spark plug means that it has current passing through it every time your spark plug fires, making the light go off and on, creating the strobe effect.
How do you hook up a timing light?
How to Hook Up a Timing Light
- Lift and prop the hood while the car engine is off.
- Disconnect the vacuum line from the distributor and plug it with the pencil tip.
- Grasp the red wire alligator clip on the timing light.
- Locate the black wire on the timing light and attach it to the negative battery terminal.
How does a digital timing light work?
The modern version is a digital dial-back light. Instead of a dial, these lights generally use a digital display screen with not just the amount of timing dialed back but also all kinds of other information. Instead of a traditional knob, these digital lights generally use up or down arrows to adjust the timing mark.
Where is the timing light on a car?
The timing light is connected to the ignition circuit to illuminate the timing marks on the car engine flywheel or crankshaft pulley when your engine is running. It indicates the current timing of the spark. INNOVA 3551 Inductive Timing Light is the best light you will find in the market.
What should I do if my timing light won’t work?
If an engine won’t start and you don’t know why, connect the timing light and crank the engine, checking to see that the light senses the pulse in the spark plug wire. If it can’t find the electronic signal, then you have just narrowed down the potential engine problems to just a spark issue.
How does a timing light work on a spark plug?
How does a timing light work? The inductive clamp is sensitive enough to “read” the pulse of the spark plug wire firing. Each time the distributor or coil pack fires through the wire to the spark plug, the timing gun senses the electrical charge and simultaneously fires a light pulse out the end of the gun.
How do you set timing on an engine?
So to set the timing, look out for a timing degree on the LED digital readout. Adjust the timing sensor probe to this mark. A timing light is the most common and sure method to time your engine. The light is also used to check the timing. In short, you will be able to identify any timing problems before they become serious.
