The ignition module is responsible for turning the ignition on and off and control the duration of the current through the primary winding of the coil. This Allows the spark plugs to fire at a specific time According To the number of cylinders your vehicle has. This allows the spark to fire at a certain time, the number of cylinders your vehicle. Testing of the ignition module can be done Using a digital volt ohm meter and a 12-volt test light. Testing the ignition module can be done using a digital volt-ohm meter and a 12-volt test light. Instructions 1) Use a wiring diagram for the year model or your vehicle. Use a wiring diagram for the model year of your vehicle. Locate the terminals enter and running out of the ignition module. Locate the terminals running in and out of the ignition module. Placement of the module Varies from model to model, so check the service manual or your vehicle appropiate for the exact location. Placement of the module varies from model to model, so that the appropriate service manual for your vehicle for the exact location. 2) Turn the ignition on and use your DVOM to check for voltage to the ignition module and the positive terminal of the ignition coil. Turn on the ignition and use DVOM to check for voltage at the ignition module and the positive pole of the coil. Place the negative lead of your DVOM to a solid ground and use the positive probe to the lead wires running to the ignition module and coil to the ignition. Place the negative lead of your DVOM a solid ground and use the positive wire to the wires to the ignition module and coil probe. 3) That shows your DVOM if voltage is present at Both locations, remove the lead and set the meter DVOM aside. If your DVOM shows that stress at both locations, remove the DVOM leads and turn the meter on the side. Connect the ground lead from the 12-volt test light to the negative terminal on the ignition coil. Connect the ground lead from the 12-volt test light to the negative terminal of the coil. Have your partner crank the engine over Several times. Allow your partner to start the engine a few times. Should your test light flicker on and off. Your test light should flicker on and off. If so, your module is working properly and no further testing is Necessary. If so, then your module is working and no further testing is required. 4) If your test light does not flicker on and off, Visually inspect the wires running out of the ignition and Writing modules. If your test light does not flicker on and off, visually the wires running in and out of the ignition module. Look for burn marks, melted wire insulation and breaks in the wires. Look for burn marks, melted wire insulation and breaks in the cables. Use your wire splicing tool to remove the bad area in the wire and use your wire connectors and splicing tool to repair the faulty wires. Use your wire tool to break the bad area to remove the wire your wire connectors and splicing tool to use to repair the defective cables. 5) Use your DVOM to check for an open circuit condition in the primary coil windings. Use your DVOM to check for an open circuit in the primary coil winding. Touch the negative probe to the negative terminal on the ignition coil, touch the positive lead to the positive terminal. Touch the negative probe to the negative terminal of the coil, tap the positive wire to the positive pole. Set the meter to read ohms. Set the meter to read ohms. If the reading shows infinite ohms, your ignition module is faulty and Should Be Replaced. If the reading shows infinite ohms, your ignition module is defective and needs replacing. Follow the service manual instructions for Replacing your ignition coil. Follow the service manual instructions for replacing your coil. 6) Look to see if the test shows low to no DVOM ohms, if so, then you have a faulty ignition module That Will Have To Be Replaced. Look to see if the test reveals little or no DVOM ohms, if so, then you have a faulty Ignition Modules that must be replaced. Follow the instructions for your vehicle service manual to replace the module. Follow the service manual instructions for your vehicle to replace the module.
