Can a bad distributor cause weak spark?
Can a bad distributor cause weak spark?
A faulty engine distributor won’t spark, which will either prevent the engine from starting or cause it a running engine to fail. In order for the ignition system to work properly it is important to keep the engine distributor operating at maximum efficiency.
How to test an inductive distributor pick up circuit?
The purpose of this test is to investigate the operation of an inductive distributor pick-up based on voltage and frequency output during engine cranking and running conditions. View connection guidance notes. Use manufacturer’s data to identify the distributor pick-up circuit. Connect PicoScope Channel A to the distributor pick-up signal circuit.
What is the function 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.
Where is the ignition pickup on a distributor?
Electronic ignition pickups are a component found on traditional electronic distributor ignition systems. They are located inside the distributor and function as the trigger for the ignition system to produce spark.
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 causes one driver or transistor to fail?
The common cause of one driver/transistor failing is a shorted ignition coil primary winding. This is a winding of wire within the ignition coil where each loop is separated by a very thin plastic coating.

What are the features of a transistor ignition system?
The transistor ignition system features a specially designed distributor, ignition pulse amplifier, and a special coil.
