How does a pickup coil in a distributor work?
In terms of the pickup coil, the conductor is the sensor. The magnet within the rotor presents a current that is picked up by the sensor as the window passes by the sensor, which is then processed by the vehicle’s ECU or ignition system.
Where are the coils on an ignition coil?
They can be located on the face of the pickup coil or on the outside of the distributor. Step 4: Replace the pickup coil: Install the new pickup coil, making sure the wire connectors and mounting screws are properly tightened. Reinstall the ignition rotor, distributor cap, and plug/coil wires. Note: Follow steps 1-3 from Method 1 first.
How do you replace an ignition pickup coil?
Step 1: Disconnect the battery: Remove the negative terminal on the battery. Step 2: Remove the distributor cap and rotor. Step 3: Remove the ignition pickup coil: Disconnect the electrical wires to the pickup. Step 4: Replace the pickup coil: Install the new pickup coil, making sure the wire connectors and mounting screws are properly tightened.
Is there a way to test a pickup coil?
You can test the pickup coil with a digital multimeter. First disconnect the two lead from the ignition module and set the meter to ohms.
Where does the pick up coil signal go in an ignition module?
This pick up coil signal is sent directly to the ignition control module. The ignition module, upon receiving this pick up coil signal (for all intended purposes it’s a crankshaft position sensor signal) converts it to a digital signal that is now sent to the fuel injection computer.
How does the distributor mounted ignition module work?
In a nutshell, when you crank up the engine (and the system is working properly): The distributor shaft starts to rotate, inducing the pick up coil to start generating its magnetic signal. This pick up coil signal is sent directly to the ignition control module.
What should the voltage be on a HEI distributor?
Disconnect the green and white wires from the module and touch the positive meter lead to the green wire and the negative lead to the white wire. The normal reading should be between 800 – 910 ohms. Testing the primary circuit of the coil. The remaining electronic part that would keep the distributor from firing is the module.
What makes the ignition coil start to spark?
Also, after receiving the pick up coil signal, the ignition control module starts to switch the primary current (of the ignition coil) On and Off. As you might already know, it’s this ‘Switching Signal’ that makes the ignition coil start sparking away.
