When to test and repair ignition system problems?
If the engine does not produce spark, other areas of the ignition system should be checked before focusing on the ignition module as source of failure (see above). If no fault is discovered, the ignition module itself may need to be examined. To best determine the cause of failure, please consult an Authorized Dealer.
What are the symptoms of a defective ignition module?
Low or no voltage to the primary (positive) side of the coil 3. High resistance or open coil wire, or spark plug wire 4. Negative side of the coil not being pulsed by the ignition module 5. Defective pickup coil 6. Defective module 4 Electronic Ignition Troubleshooting Procedure
Are there any drawbacks to an ignition system?
No battery maintenance problems. 4.4 DRAWBACKS (DISADVANTAGES) OF CONVENTIONAL IGNITION SYSTEMS Following are the drawbacks of conventional ignition systems : (a) Because of arcing, pitting of contact breaker point and which will lead to regular maintenance problems.
When to check the triggering signal from the ignition distributor?
Check the triggering signal from the ignition distributor, ignition control unit, or engine control unit During all testing work on the ignition system, please note that faults established during tests with the oscilloscope are not necessarily faults caused by the electronic system; they can also be caused by a mechanical problem in the engine.
Low or no voltage to the primary (positive) side of the coil 3. High resistance or open coil wire, or spark plug wire 4. Negative side of the coil not being pulsed by the ignition module 5. Defective pickup coil 6. Defective module 4 Electronic Ignition Troubleshooting Procedure
How to troubleshoot an ignition system in a car?
5 Electronic Ignition Troubleshooting Procedure (continued) • Step 2 • Connect the voltmeter or test light to the negative side of the coil and crank the engine. • The voltmeter should fluctuate or the test light should blink, indicating that the primary coil current is being turned on and off.
What are the different types of ignition systems?
Types of Ignition Systems Solid-state systems: the more modern option, these systems use a tiny transistor in the coil or armature to close the electrical circuit that travels through the spark plug lead to the spark plug(s)
What causes no spark in coil and ignition system?
• A good coil and ignition system should produce a blue spark at the spark tester. • Typical causes of a no-spark (intermittent spark) condition include the following: 1. Weak ignition coil 2. Low or no voltage to the primary (positive) side of the coil 3. High resistance or open coil wire, or spark plug wire 4.
