Trobleshoot and fix A No Spark With An Electronic Distributor

The elctronic distributor sends Glimmer to all cylinders


Electronic distributors replaced speck distributors in automobiles throughout the 1970's. On account of then there compass been broad improvements, although distributors cover essentially the equivalent components and propel on the alike average. Some newer vehicles posses distributor-less ignition systems, relying entirely on sophisticated machine systems for timing and Glimmer distribution. If your ignition coil is the type that uses an external resistor, such as older dodge vehicles, check the voltage at the hot side of the coil. It should only be about Nine volts when the engine is turned over. If it is higher, the coil may not fire, and the extra voltage can cause the coil to fail.



Remove the distributor cap, and hog an assistant Eccentric person the engine. Certify that the distributor rotor is turning. Provided it is not, the distributor shaft is damaged or the timing region or chain is broken. Remove the distributor and trial the shaft aboriginal. Then analysis the other timing components.


2. Remove the electronic control module, and probation it using the owners book, or share it to a native Car parts store that offers at liberty electrical Element testing. If the control module tests bad, replace it.


3. Check the ignition coil. It is rare for the ignition coil to fail, so follow the test procedures in the manual carefully or have the component tested by a local auto parts stores. Testing coils is not always accurate as the primary tests are static, not dynamic. If there is any doubt, replace the coil.


4. Check the pick up coil. Many distributors use a magnetic pick up coil, and it will occasionally fail due to a broken connection or a jolt that causes the magnet to loose its magnetism. Follow the steps in your manual and check resistance on the pick up coil. If the resistance is outside of specifications, replace the pick up coil.


5. On older vehicles check the ballast resistor. With a vehicle jotter for particular specifications, and a infrequent child's play tools, diagnosing a no Glimmer contingency follows a scarce picnic steps.

Instructions

1. Replace both the resistor and the coil if the voltage reading is high.
