WHAT IS TIMING?
In order for an automobile engine to function, three things are necessary: air, fuel, and a spark to ignite the air/fuel mixture and create an explosion. The precise instant of that explosion must be such that the maximum power is delivered to the engine piston. This is “Timing.” Each engine manufacturer determines at the factory the exact timing necessary for various engines so that each ounce of power is obtained from every gallon of fuel. Due to normal engine and ignition system wear, the timing can change and will reduce both power and mileage. With the Xenon timing light, the car owner can reset the timing to the new car standards and regain lost power and increase mileage.Timing is given in degrees Before Top Dead Center (BTDC) or After Top Dead Center (ATDC) in the manufacturer’s specifications. In order to completely burn the air/fuel mixture in the car’s engine cylinders, most timing is such that the spark occurs at a point several degreesbefore top dead center (for example, 4 BTDC) to assure that full power of the explosion is obtained.Two additional terms that manufacturers use when describing timing are; “Advanced” and “Retarded.” When the timing is advanced, the spark will occur before the piston reaches the top of the engine cylinder (BTDC). On some late model cars equipped with various emission control devices, the timing is retarded so thatthe spark occurs after the piston has started down in the cylinder (ATDC). Engine timing is changed by adjustment of the ignition distributor.In order to allow setting and adjustment of the engine timing, special “Timing Marks” are provided on each engine during assembly. In most cases, these marks appear on the engine harmonic balancer attached to the crank pulley at the lower front of the engine.
WHEN TO CHECK TIMING
The instant of spark plug firing is determined by the opening of the distributor ignition breaker points and will change any time the point gap or dwell angle is changed. In addition, normal wear on the breaker point‐rubbing block will have the same effect on the point gap or dwell angle. While cars equipped with the new “breaker less Electronic Ignition Systems” will not normally change timing since there are no breaker points, the timing light can still be used to note changes in timing caused by troubles in the ignition system as well as for resetting timing when components are changed or he vehicle is tuned.
TIMING SPECIFICATIONS
As noted in earlier paragraphs, timing requirements vary from engine to engine and for this reason, the engine manufacturer’s specification should always be referred to before making an adjustment. These specifications are contained in the car owner’s manual, and typically on the underhood decal specifications.
GENERAL OPERATING PROCEDURES
- Locate engine‐timing mark, see figure 1. Us a rag to clean all grease and dirt from the mark and the pointer. It may help to use chalk or white paint on the marks to make them more easily seen.
- Check manufacturer’s specifications for correct timing for the engine being serviced.
- Start and run the engine until the normal operating temperature is reached. Approximately 15 minutes. Stop engine.
- If specifications require, locate the vacuum line going to the ignition distributor vacuum advance and disconnect and plug the line. A golf tee or small pencil may be used to seal the line.
- Connect the timing light as shown in figure 2.
- Start the engine and operate at normal idle speed. Aim the timing light at the timing mark, be cautious of moving parts.
- Trigger the timing light and observe the reading from the timing mark.
CAUTION: Use care when working around the moving engine. The stroboscopic action will make moving parts appear to be in slow motion. Keep hands, tools, and timing light clear of moving fan, belts, or other moving parts.
GENERAL OPERATING PROCEDURES CONT.
- Compare reading obtained in step 7 with manufacturers’ specifications. If timing is not as specified readjust as described in the following procedure
- Stop engine.
INSTRUCTIONS
Adjusting Timing to Specification
- Loosen distributor hold down locking bolt located at the base of distributor enough so that distributor may be rotated back and forth, Do not over loosen or remove bolt but leave tight enough to prevent the distributor from turning by itself.
- Start and warm engine to normal operating temperature
- Direct timing light flashes at timing marks and slowly rotate the distributor right and left until the timing marks are realigned with a pointer to factory spec., see figure 1 above.
- Stop engine.
- Tighten distributor hold down bolt‐using care not.
- Start the engine and recheck the timing.
To use an advance timing light for checking the “Idle Timing”
Adjust the advance to 0 (zero) on the timing light with the + and – buttons located on the back of thetiming light, see figure 3.Follows the “Operating Procedures In General” from above.
- Pull the trigger on the timing light, point the light at the timing mark on the vehicle.
- Use the + or – buttons on the timing light see fig. 3, to move the mark to the 0 (zero) line on the harmonic balancer in fig. 4
- Look at the figure on the back of the timing light, this is your Idle Timing.
Checking the Centrifugal Advance and Vacuum Advance
- Follows the “Operating Procedures In General” from above, except increase the engine speed to 2000 rpm. Refer to the factory owner’s manual for the recommended rpm.
- Trigger the timing light and use the + an – buttons located on the back of the timing light. Stop when the timing mark moves to TDC or O position.
- Look at the figure on the back of the timing light, add this to your idle timing figure. This is your Total Timing.
- Compare the reading with the manufacturer’s specification.
INSTRUCTIONS CONT.
Testing Centrifugal Advance
- With the timing light still connected and with the vacuum line disconnected:
- Speed the engine up slowly and watch the timing mark.
- The timing mark should remain stationary until the engine reaches the manufactures specified speed. The timing mark should then move steadily and without jerking.
- If the mark does not move, or if it moves erratically, the centrifugal (automatic) advance should be serviced as necessary.
- To check the maximum advance stop the engine.
- It’s necessary to mark the harmonic balance with the maximum degree per manufacturer’s specifications and follow the manufacture’ procedures.
Testing Vacuum Advance
- The vacuum line to the distributor must be connected to make this test.
- Set engine speed to 800 R.P.M or speed necessary to apply vacuum to the distributor.
- Aim the timing light and note the position of the timing Mark.
- Disconnect vacuum line.
- If the timing mark does not move, the trouble could be a plugged line. A leaky diaphragm or afrozen distributor Plate and the distributor should be serviced as required.
Checking Distributor Cam Wear
- This check is done after the timing has been set and the timing mark lines up with the reference pointer for #1 cylinder.
- Connect the timing light to the wire directly opposite (180) #1 cylinder on the distributor cap, see figure 5.
- Start the engine and aim the timing light towards the timing mark. The reading should be the same as when connected to #1 cylinder.
- If reading is not the same, the probable cause is worm out distributor cam or bent distributor shaft. Repair as required.
Small Engines
The DC power Timing Light can be used on any combustion engine with impulse ignition, magneto ignition, such as motorcycle, lawnmowers, outboard motors, or any time there is a high voltage spark used for ignition.When 12 Volt DC voltage is not available from the engine being tested, an external battery of 12V must be used. Connect a ground from the negative post of the external battery to the engine.Connect the red clip to the (+) positive terminal and the black clip to the (‐) negative terminal of the battery. Connect the adaptor lead of the timing light to the proper spark plug.
INSTRUCTIONS CONT.
Rotary EngineThe timing Light can be used on rotary engines. Follow the manufacture’s specific instructions and specifications. Below is a typical procedure for the Mazda twin-rotor engine.
- Connect the Red and Black power leads clamps to the battery. Connect the wire with the spark plug adaptor to the leading spark plug on the front rotor housing.
- Start the engine and run at idle speed.
- Aim the timing light at the timing indicator pin on the front cover
- Loosen the distributor locking nuts and rotate the leading side distributor body until the timing mark on the eccentric shaft pulley is in line with the timing indicator pin.
- Tighten the locking nuts and recheck the timing.
- Repeat the above step for setting the trailing side distributor timing with the timing light connected to the trailing spark plug.
TROUBLESHOOTING
Ail timing lights are tested 100% before they are shipped from the factory and improper operation is usually caused by incorrect hook‐up. Please observe the above troubleshooting procedure if the timing light fails to perform satisfactorily.
| SYMPTOM | PROBABLE CAUSE | SOLUTION |
| No Flash | Switch in the “OFF” position. | Move the switch to the “ON” position. |
| Battery clips connected backward. | Reverse the battery clip connection. | |
| Poor connection of clips. | Make sure the clip is connected to a clean battery post. | |
| No Flash but double-check indicator is “ON” | Wrong direction of the inductive clamp. | Toward the arrow on the clamp to #1 plug. |
| Weak ignition or spark plug. The gap is too close. | Connect to other plugs or spark plug wires. If flashes then repair the plug gap. | |
| Fault Lamp | Replace it. | |
| Light Flashes Intermittently | Timing light high-tension wire lying on or too close to the other spark plug wires. | Place the high tension wire in good order so it is routed away from the other spark plug wires. |
