How do you test a magnetic pickup distributor?
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 to test a GM distributor?
Testing the GM HEI Distributor Check the rotor and the cap for excessive wear. Check the coil tower for excessive wear. Remove the top plastic cap on the distributor cap. Use an ohmmeter and check the coil positive terminal to the metal case of the coil.
How to check if a coil is sparking?
Turn the ignition ON. Touch the probe of the test light to the smaller terminal of the module--it's labeled "G" and had the Green pickup coil wire connected to it. When you pull the probe OFF the terminal, you should hear a snap (the spark) from the coil.
What causes HEI module failure?
Subsequently, question is, what Causes HEI module failure? Most common cause of module failure is still overheating of the in cap coil, and its layer shorting, causing increased resistance the coil trigger side of the module cannot handle.
Where to test battery voltage?
Test for power at the pink BAT terminal. You should have battery voltage w/ the key in the start and RUN positions.
What happens if the hot wire from the battery feeds the distributor has no voltage to it?
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.
What does checking an ignition coil tell you?
Testing or checking an ignition coil can tell you a lot about the health of your ignition system. Since the coil is the center of the system, it has to be working right or the car will not run right. Testing the coil requires an ohms meter. If you do not have one, you can buy one at a home center or building center that carries electrical supplies.
How to read ohms on a coil?
Place a lead from the ohmmeter on either side terminal and one in the center high tension terminal. Read the ohms off the meter. You are looking for 7500 to 10,500 ohms, and if the reading falls outside that range, it indicates a defective coil.
How to remove coil wires from distributor?
Remove the wires from the positive and negative terminals on the coil using a wrench to remove the nuts from the studs. Unplug the coil wire that runs from the coil high tension terminal to the distributor and lay it aside.
How to tell if a coil is defective?
Place one test lead from the ohms meter on the negative post and one on the positive post of the coil. it doesn't matter which lead goes on which post because you are measuring resistance, not amps or volts. The reading should be between .70 and 1.7 ohms. If it is outside that range, the coil is defective.
How to reattach coil wires?
Reattach the wires to the positive and negative side terminals followed by the retaining nuts for both sides. Tighten the nuts with a wrench. Plug the coil wire back into the high tension terminal in the center of the coil. If the coil is outside the ranges here, do not reinstall it. Instead, replace the coil right away.

How many coils does a car have?
The number of pickup coils into a vehicle varies, and this is usually dependent on the manufacturer’s design. Therefore, some cars feature two ignition coils whereas others only have one, with the role being to fire of several spark plugs, and this it does occasionally using low resistance ignition cables. Moreover, some designs opt for one pickup coil for every spark plug, and it is then fixed right above the spark plugs.
What is an ignition coil?
An ignition coil is an essential component every modern engine management system; hence nearly every car that is made nowadays incorporates an ignition coil as part of the secondary ignition system. The ignition coils typically make use of electromagnetic induction to transform the twelve volts in the car to thousands of volts needed to produce a spark that has enough power to jump across the gap in the spark plug.
What is the resistance of an ignition coil?
Typically, an ignition coil has a primary resistance ranging between 0.4 and 2 ohms, but you should always make a point of confirming this from the manufacturer’s manual. If it reads zero, you should then know that the ignition coil is damaged due to an internal short and needs to be replaced.
