- pull pc board up ,,,,now you have access to the bottom leads of the magnetic pick-up.
How do I know if my magnetic pickup is bad?
- Engine Fails to Start. If the positive hot wire from the battery that feeds the distributor has no voltage to it, the HEI distributor will not function. …
- Plug Wire Engine Miss. …
- Reduced Fuel Economy. …
- Weak Spark. …
- Electrical Arc and Shorts. …
- Hard Starting. …
- Smog Check Failure.
How do you remove a pickup coil from a distributor?
- Materials Needed.
- 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.
Where is the pickup coil located?
A pickup coil is essentially a sensor that can be found
within the rotor
. This metal rotor is located on top of the distributor shaft and has windows that are equal to the number of cylinders in the vehicle’s engine. The distributor shaft is driven by the camshaft using a gear.
How do I change an ignition pickup coil?
- Materials Needed.
- 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.
How do I know if my distributor pickup coil is bad?
- No Engine Spark. The pickup coil sends the signal from the ignition module to the spark plugs during the ignition process. …
- Rough Idle. Because the spark plugs are not communicating proper timing to the fuel injectors, a rough idle may occur. …
- Engine Stall/Failure to Accelerate.
What is the pickup in the distributor?
They are located inside the distributor and function as the trigger for the ignition system to produce spark. The pickup coil
monitors the rotation of the distributor
and triggers the ignition system at the optimal moment to produce the best timed spark for best engine performance.
How do you check a pickup coil?
Connect the red (positive) lead of the multimeter to the outer, positive terminal of the ignition coil. Turn the reading
dial on the multimeter to ohms
to measure resistance of the primary pickup coil. (The Greek letter omega denotes ohms.)
What are the symptoms of a bad ignition coil?
- Engine misfires.
- Rough idle.
- A decrease in car power, especially in acceleration.
- Poor fuel economy.
- Difficulty starting the engine.
- Check engine light is on.
- Exhaust backfiring.
- Increased hydrocarbon emissions.
How do you check a distributor pickup coil?
On distributors with the pickup separate from the module assembly, you can check the pickup
using your Ohm meter
. Connect the leads from your Ohm meter to the 2 leads of the pickup. If you show a resistance of 50 to 200 Ohms, the pickup is functioning correctly.
How does ignition pickup work?
The pickup coil consists of a hall effect sensor, which is housed within a metal rotor mounted on top of the distributor shaft. … As the rotor spins, the windows pass in front of the sensor, exposing it the magnet which triggers a
signal to the car’s ignition system
which then fires a spark within the firing order
How do you test a 5.0 ignition coil?
The only safe way to test for spark is to use a spark plug tester tool. If a coil problem is suspected,
measure the coil’s primary and secondary resistance with an ohmmeter
. If either is out of specifications, the coil needs to be replaced. A coil can be easily bench tested with a digital 10 megaohm impedance ohmmeter.
What is an ignition module?
The ignition module is
responsible for firing the spark plugs
. Each spark plug must fire at exactly the right time for the engine to run properly. The ignition module uses input from the crankshaft position sensor or camshaft position sensor to determine when to fire the spark plugs.
What are the signs of a bad distributor?
- Engine misfires. Engine misfires can occur for a number of reasons. …
- Car doesn’t start. …
- Check Engine Light comes on. …
- Excessive or unusual engine noises.
How does a distributor magnetic pickup work?
- As the distributor shaft turns, the reluctor wheel also turns.
- The tabs on the reluctor pass by the magnetic pickup. …
- As the tab passes by the pickup, it creates pulses in the magnetic field. …
- The control module interrupts the voltage to the coil, causing it to fire.
How do you change a distributor pickup?
- Materials Needed.
- 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.
