Electronic Ignition System Troubleshooting

2017 HPBExpo Education Sponsored by. If your car has an electronic ignition system the ignition module may have gone bad.

Ignition Systems A Short Course Carparts Com Ignition System Ignite Car Repair Service

Turn Ignition Switch OFF.

Electronic ignition system troubleshooting. Make sure that the ignition switch is off and disconnect all wires from the coil. The pickup coil monitors the rotation of the distributor and triggers the ignition system at the optimal moment to produce the best timed spark for best engine performance. Divide your voltage measurement by your coil resistance.

A DC voltohm meter can be used to check the continuity of the pick-up coil. That onoff cycling is what points do mechanically or in the case of an electronic system a difference in magnetic field is detected by the pick-up coil. When the ignition switch is closed ie.

In 1992 Jeff mounted ignition coils on an aluminum plate added a. Electronic Ignition Troubleshooting Procedure When troubleshooting any electronic ignition system for no spark follow these steps to help pinpoint the exact cause of the problem. The initial idea for an aircraft electronic ignition system was generated by an experimenter named Jeff Rose.

The switch is ON the reluctor rotates which makes the teeth of the reluctor cone closer to the permanent magnet. Now the maximum system amperage can be determined. This could also be caused because the timing of.

If the voltage measured is approximately 12 volts no resistance wire is present. A typical resistance wire will provide 9 - 6 volts. Jeff went ahead and did what many thought impossible at the time.

There are eight sharp points that rotate past the pick-up without contact each correlating to a cylinder However this signal is not strong enough to be used to turn. If any of the ignition points are corroded then this wont allow the electrical starting system to spark and light the fuel. They are located inside the distributor and function as the trigger for the ignition system to produce spark.

The impulse the ignition module produces is not enough to spark the compressed air-fuel. Electronic ignition pickups are a component found on traditional electronic distributor ignition systems. The magnetic field is passed on to the pick up.

As the ignition pickup essentially functions as the activation switch for the entire ignition system. Thus the reluctor provides a path for the magnetic lines from the magnet. Once it has been determined that there is no spark there are a few quick checks that can be performed to determine the cause.

Electronic ignition systems had conceptually been considered for aircraft for many years but Jeff decided to do more than simply think of how to put it all together. Adjust your meter to the lowest ohm scale. Turn the ignition switch off.

Electronic Ignition Overview this collapse by absorbing the initial shock current of the primary winding. Troubleshooting Electronic Ignition Bob Wise CVC Coaching This session is designed to provide a broad approach to troubleshooting electronic ignition systems. It can be checked at the leads as they leave the distributor or on pins 4 and 5 of the ECU connector.

Electronic ignition system Working of Electronic Ignition System. Make sure the ignition switch is off when removing or replacing the control unit connector. If you are using an analog style meter make sure to zero the needle.

Because these vehicles have high-energy ignition systems that operate at 47000 volts or higher the old technique of pulling a distributor or spark plug cable to test for a spark is unsafe. Troubleshooting a Hot Surface Ignitor HSI The hot surface ignitor HSI is the most commonly used electronic ignition system. Having trouble with your gas grill ignition.

Also check that the ignition coil is in good condition if it is showing signs of wear you should replace it. If you have the EFI electronic fuel injection system you wont have to deal with setting the timing the system will do this itself based on the current RPM and other parameters. This happens because removing power from the coil induces the HV charge.

Also one important step in troubleshooting the ignition system is having the key in the on position for many of the tests. Step 1 Turn the ignition on engine off and using either a voltmeter or a. And the negative black lead to an engine ground.

Testing the Coil or Armature Clip one end of the spark tester service part number 19368 to the ignition cable and the other grounded to the cylinder head. Now read the voltage at the positive coil terminal. It helps shape the coil collapse to produce the high power secondary collapse AND slows the collapse of the coil just long enough for the points to get far enough apart so the coil back EMF output wont arc across the points.

Most are made from silicon nitride or silicon carbide. Make sure you turn the key back to the off position after each test or you will potentially damage some of the components in the system. The coil is probably the easiest thing to check and therefore the first thing to check when embarking upon ignition system troubleshooting.

Measure from the negative terminal to the positive terminal. It reduces the air gap between reluctor tooth and sensor coil. Disconnecting the plug from the ECM with the Ignition key ON can damage the ECM module.

Remove wiring plug from the Control Unit ECM. Turn the ignition switch to the run position. Various hearth electronic systems will be discussed as well as common methods of diagnosing most frequently encountered electronic ignition problems.

It works like a light bulb filament heating up when electricity is passed through it. Write your measurement down. Troubleshooting an electronic ignition system is fairly simple.

Heres some tips and tricks to help you light your grill.
