What should the resistance of a distributor be?
For this style distributor, the only real specification is to check the resistance of the magnetic pickup. Use an ohm meter across the two wires and confirm that the resistance is between 400 and 1,300 ohms. If the pickup is out of this specification, it may not be triggering the ignition box.
What should the resistance be on a distributor pick-up sensor?
Verify Distributor Pick-up Sensor resistnace is between 350 to 550 Ohms. If resistance is correct, the wiring from the ECM plug to the distributor plug is defective. Repair wiring. Verify there is no continuity (open circuit; maximum resistance).
How to test the resistance of the ignition switch?
Test the resistance of the distributor pickup coil with the ignition switch remaining in the “Off” position. Unplug the distributor wire harness from the black plastic connector. Measure the resistance between the two parallel prongs of the distributor harness.
How does a magnetic pickup distributor system work?
How does a magnetic pickup distributor work? 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.
For this style distributor, the only real specification is to check the resistance of the magnetic pickup. Use an ohm meter across the two wires and confirm that the resistance is between 400 and 1,300 ohms. If the pickup is out of this specification, it may not be triggering the ignition box.
What should the resistance of a pickup be?
Furthermore, the ignition coil resistance of your pickup should range between 6,000 to 10,000 ohms, and it is advisable you confirm this from the manufacturer’s manual in case you are uncertain on the right range.
What should secondary resistance be on HEI distributor?
Testing the secondary circuit of the coil. The primary resistance value should be between 0.6 – 1.5 ohms.
What do I need to troubleshoot a performance distributor?
To do this, you will need a 1/4-inch nut driver and a multi-meter. To test the resistance of the coil, remove the coil cover so you can see the red and yellow wire. Using the multi-meter set on the ohms setting, touch the positive lead to the red wire terminal and the negative lead to the yellow wire terminal.
