Inspect/Test/Replace

• Perform a no-start diagnosis of the ignition system.
• Use an ohmmeter to ensure that the ignition module connection to ground is good. one lead of the meter should be connected to the ground terminal at the module and the other to a good ground. zero resistance indicates good continuity in the ground circuit. any resistance reading during this test is unacceptable.
• The most effective method of testing for a defective ignition module is to use an ignition module tester, if one is available for that module.
• Keep in mind that ignition modules are very reliable. They are also one of the most expensive ignition system components. So, if a module tester is not available, check out all other system components before condemning the ignition module.
• The control module can be tested at any of our store locations.
