Check the listing for details. Advance Ignition Timing Light Inductive 12V Engine Automotive Timing Gun Lamp US. Color: Black, Condition: New. Listed at 29.99 USD. Description:1, ignition timing tool for cars, motorbikes and all two-stroke or four-stroke petrol engines, using impact-resistant ABS shell, working voltage of 12 V, ignition timing light can be very intuitive detection of the engine flywheel or pulley ignition timing degree to make appropriate adjustments, can detect the car burst suppression control system, vacuum advance angle control system, with the change of speed and change the advance angle, the ignition timing light can be used to detect the engine flywheel or pulley ignition timing degree to make appropriate adjustments. Under the long-term normal wear and tear of the engine, the timing belt and pulley are regularly replaced, and the cylinder pressure drops, all the ignition timing adjustment should be done again. 2, ignition timing of the early, late directly affect the normal operation of the engine. Seriously will lead to the engine can not start. If the ignition is too late, it will lead to difficulty in starting or lack of power, which will cause fuel consumption and accelerate engine wear. Why You Need Timing Lights Under the long-term normal wear and tear of the engine, the timing belt and pulley are regularly replaced, and the cylinder pressure drops, so the ignition timing needs to be readjusted to improve engine performance and efficiency. Timing light automotive can be used to record timing changes due to ignition system failure or resetting timing when vehicle components are changed. QA1: Works on diesel engines? Answer: No, diesel vehicles do not have spark plugs or distributors, so these indicator lights will not work on diesel engines QA2: Works on 6V volt system？ Answer: Yes, on 6 volt electrical systems use a 12 volt auxiliary battery to power the indicator light. Connect the BLACK clip to the negative (-) terminal and the RED clip to the positive (+) terminal of the 12 volt auxiliary battery【Advance Function】 The timing light is designed to re-timing your car's ignition to get the best performance that you can.Capable of testing the ignition timing scale on the engine flywheel or belt pulley intuitively to adjust appropriately.Able to detect the automotive knock suppression control system and vacuum advance angle control system, change its advance angle with the speed change.【Wide Application】 This engine timing light is suitable for automobiles, motorcycles, ATVs, RVs, boats and all two-stroke or four-stroke gasoline engines, easily operate on 12V ignition systems. Its speed is up to 1000rpm. 【Multiple Protection Functions】 The ignition timing light has the function of reverse polarity and overload protection, which can effectively protect the safety of batteries and equipment. In addition, the metal alligator clip is also covered with a rubber sleeve protector, which is safer to apply.【Strong Flash & Sliding Sensor Clips】 The sensor clip is red and black to distinguish positive and negative poles, easy to use and more secure. It's sliding clamp-on inductive pick-up, for easy and safe hookup.The special blue-white xenon tube can produce a very strong flash,so that it can work even in the daylight. 【Handle Pistol-type design】 Ergonomically designed with comfortable press keys, great Press feeling and easy operation.The shell of ignition timing light is made of high-quality ABS material, which is durable and can maximize the service life.【Attention】 The power supply is 12V with red connecting to positive and black to negative. The high voltage wire induction clamp is clamped on the high voltage line of cylinder with the arrow on the induction clamp pointing to the direction of the spark plug for normal working. How to Use: Easy Operation: Clamp the red clip to the positive terminal of the vehicle's battery. Clamp the black clip to the negative terminal. Hook up the spark plug sensor clip to the high voltage line of the No.1 cylinder. Note: The arrow on the sensor clip should point to the direction of the spark plug to work properly. 1.Start the engine to warm up to the normal working temperature; 2.Clamp the red clip to the positive terminal of the vehicle's battery. Clamp the black clip to the negative terminal. Hook up the spark plug sensor clip to the high voltage line of the No.1 cylinder; 3.Adjust the engine speed to the normal idle speed state, use the ignition timing light to illuminate the timing pulley, and check whether the mark on the pulley is the angle specified by the manufacturer (usually 6~10); 4.If it is necessary to adjust, loosen the distributor screw, use the ignition timing light to aim at the timing pulley, then turn the distributor (turn left and right) until the scale mark is at the specified value, and finally lock the distributor screw.Reverse Connection Protection Timing light: is deigned with polarity reverse connection protection. It will prevent the user from damaging the device or affecting the car or battery in the event of mis-operation. Timing light also has overload protection. If the current or load is too large during the operation, timing light will automatically disconnect the current to protect the battery and device. Application Suitable Applications : Automobiles, motorcycles, ATVs, personal watercraft, RVs, boats, airplanes, golf carts, lawn mower etc,All two-stroke and four-stroke gasoline engines, easily operate on 12V ignition systems. What to do if the Ignition timing light can't light up? 1. The right way to clamp 2. Corrent way to current 3. Clamp like this ,it will light up every time 4. Sometimes,the electr-omagnetic pulse signal of thr first the cylinder of the engine is insufficient,Which will cause the light to not light up Auto ignition timing adjustment method: No timing light adjustment method(1) Firstly, adjust the distributor contact gap to be suitable as required.(2) Find the first cylinder compression upper stop position. Remove the high voltage distributor wire of the first cylinder. Remove the first cylinder spark plug with spark plug sleeve, block the spark plug hole with thumb or cloth ball, then crank the engine crankshaft. When you feel resistance in the cylinder, slowly crank the crankshaft, while observing, so that the timing marks are right.(3) Adjust the minute power large to the moment of contact closure. When the above parts have met the requirements, turn on the ignition switch, loosen the distributor housing fixing screw, turn the distributor housing to make the disconnector contacts close. Then turn the distributor again in the reverse direction to the distributor contacts just open, this moment can be seen between the contacts to produce a small electric spark, then tighten the distributor housing fixing screw, and adjust the octane value to the scale to zero position; at this time, the direction pointed by the distributor head is the position of a cylinder.(4) Insert the high-voltage distributor wire on the distributor cover in the ignition order and tighten the screw by hand to temporarily fix the distributor.(5) Start the engine to test the ignition timing, if the engine ignition system and fuel supply system is well adjusted, the engine exhaust pipe should drip, the engine vibration is minimal and noise is reduced to a minimum. Timing light adjustment method(1) start the engine to warm up to normal working temperature.(2) the ignition timing light 2 collets are connected to the battery positive (red), negative pile head (black), the sensor clip in the first cylinder on the high voltage wire.(3) Adjust the engine speed to normal idle state, use the ignition timing light to shine on the timing pulley, check whether the mark on the pulley is the manufacturer's specified angle (generally 6~10).(4) If adjustment is needed, loosen the distributor screw, use the ignition timing to align the timing pulley and then turn the distributor (left and right) until the scale mark is at the specified value, and finally lock the distributor screw.
