ignition module for my car

Replace a Spare part Ignition module – a defective one or if the limit of use has been already reached. Find out useful information about Ignition module

Faults of the ignition module

• interturn breakdown;
• open primary circuit;
• burnout module;
• breakdown of the secondary windings.

Symptoms of ignition module failure

• interruptions in the engine operation;
• reduction of engine power;
• emergency stop of the engine;
• unstable idling;
• jerking of the car during acceleration;
• no voltage on the cylinder 2 and 3 or 1 and 4.

Causes of the ignition module failure

• too high or low wire resistance;
• installation of improper components;
• increased spark gap of the spark plugs;
• mechanical damage.

Diagnostics

For the diagnosis of the ignition module you need an ohmmeter or a multimeter, which will measure the resistance. To test the earth fault one wire of the device should be connected to the center module contact, and the second to the earth. With proper working module there will be no reaction of the device, and the display will show infinity. Wire terminations should be checked in pairs. The ohmmeter must be connected to the cylinders. No response from the device indicates failure.

To test the module primary circuit the ohmmeter wire must be connected to the left and right contacts. No changes in reading will indicate a module fault. All figures should be compared with the maximum permissible values ​​as specified by the manufacturer.

Do not forget to check the body of the module. At any damage it is advisable to replace the item.

Repair of the ignition module

In most cases, the module cannot be repaired. Just the module contacts are maintainable. For repair work you will need wires, a screwdriver, a soldering iron, varnish, flux for soldering aluminum. You must remove the cover of the module housing, clean up the board of small wires, replace them with new ones. You also need to replace the wire of transistor controllers. The soldered spot is necessary to be varnished.

Replacement of the ignition module

For the part replacement a set of wrenches and a hexagon spanner are required. It is necessary to disconnect the negative terminal of the battery, remove the wire box. Then disconnect high-voltage wires, remove the attachment to the motor. Dismantling is not difficult, since the module binding system is not complex. Next you need to install the new module, connect the wires to the appropriate cylinders and assemble parts in reverse order.
