How a Pickup Coil in a Distributor Works

Purpose. The distributor is an integral component of the ignition system, routing voltage from the ignition coil to fire the engine's spark plugs in sequence.
Operation. The pickup coil consists of a hall effect sensor, which is housed within a metal rotor mounted on top of the distributor shaft.
The Hall Effect. ...

The function of a distributor pick-up is to provide a timing reference signal to the Ignition Control Module (ICM) or Engine Control Module (ECM) to indicate the mechanical dwell period for each ignition event. The mechanism requires a rotating reluctor and a stationary pick-up coil with a magnetised core.

What is the purpose of a distributor pick up?

The function of a distributor pick-up is to provide a timing reference signal to the Ignition Control Module (ICM) or Engine Control Module (ECM) to indicate the mechanical dwell period for each ignition event.

What is a distributor pick up coil?

A distributor is an ignition system device used by a vehicle’s engine to send voltage to the spark plugs from the ignition coil in the proper firing order. The engine’s pick up coil determines this firing order. A pick up coil refers to a sensor device contained in a rotor.

Can you replace the distributor and pickup at the same time?

In some vehicles, the pickup can be replaced while the distributor is left in place. In others, it may be easier to remove the distributor. This method involves leaving the distributor in place. Step 1: Disconnect the battery: Remove the negative terminal on the battery.

What is a distributor pick-up voltage test?

Distributor pick-up (inductive) - voltage. The purpose of this test is to evaluate the correct operation of an inductive distributor pickup based on the output voltage and frequency during cranking and engine run conditions.

How do I know if my distributor is picked up?

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 do you test a distributor pickup?

If this was an analog meter you'd see the needle swinging back and forth.

How do distributors work?

As the engine rotates, the distributor shaft cam turns until the high point on the cam causes the breaker points to separate suddenly. Instantaneously, when the points open (separate) current flow stops through the primary windings of the ignition coil. This causes the magnetic field to collapse around the coil.

What does a magnetic pick up do in a distributor?

The magnetic pickup is actually a wire that is wound around a magnet to create a magnetic field. Whenever this field changes, due to another metal object coming into the field, a voltage is generated. MSD uses this voltage as a trigger sig- nal for the ignition control.

What is a pickup in ignition system?

The pick up coil is designed to generate a voltage pulse that is used by the ignition module as an RPM and timing sensor. The pick up coil is used in conjunction with the ignition module to provide switching of the ignition coil at the correct time and for the correct duration.

How do you know if the pickup coil in your distributor is bad?

Engine stalling One of the first symptoms of a bad ignition pickup is an engine that stalls. An old or failing ignition pickup may cut out signal intermittently, which may cause the engine to stall. The engine may suddenly just shut off, almost as if the key had been turned off.

How are distributors paid?

The way a distribution company makes money is simple. The company buys the product at a lower price from the manufacturer and sells it at a higher price to a retailer or customer.

What is the purpose of the distributor?

A distributor is an entity that buys noncompeting products or product lines and sells them direct to end users or customers. Most distributors also provide a range of services such as technical support, warranty or service. Distributors are essential in helping reach markets manufacturers could not otherwise target.

What are the 3 types of distribution?

The three types of distribution channels are wholesalers, retailers, and direct-to-consumer sales. Wholesalers are intermediary businesses that purchase bulk quantities of product from a manufacturer and then resell them to either retailers or—on some occasions—to the end consumers themselves.

Why is it called a pickup coil?

A coil of wire doesn't respond to a magnet field but rather to a change in magnetic flux through its ends. Such a coil is commonly called a pickup coil or a search coil.

What is a distributor in an engine?

The distributor is an integral component of the ignition system, routing voltage from the ignition coil to fire the engine's spark plugs in sequence. The pickup coil determines this firing order as it spins within the distributor, using a magnetic sensor in place of mechanical breaker points.

How does a pickup coil work?

This shaft is spun by a gear that is driven by the camshaft. The rotor incorporates windows that open into a small gap between the rotor and a stationary permanent magnet. The number of windows correlates to the number of cylinders in the engine. 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.
