How many ohms should a Ford coil have?

Your coil should have a reading of between 6,000 and 15,000 ohms for your Ford.

How do you test a coil over plug with a multimeter?

Connect your multimeter to the positive terminal or pin of your coil, and to the high output terminal that goes to the spark plug. Most ignition coils should have a secondary resistance falling somewhere between 6,000 to 10,000 ohms;however, refer to manufacturer specifications for the correct range.

How many ohms should a 12 volt ignition coil have?

The normal, acceptable range for a standard 12-volt car is 1.5 to 1.7 Ohms.

How many ohms Should a coil pack read?

The ohmmeter should read between 6,000 to 30,000 ohms. If the readings are above 30,000 ohms or below 6,000 ohms, replace the coil pack. Reinstall the coil pack into the engine bay and reconnect all the electrical connectors. Plug the spark plug wires into the coil pack in the correct order.

How many ohms should a 12 volt coil read?

You should have a resistance reading of at least 3-4.5 ohms. A bad coil will show a higher reading then 3-4.5. Next, place the red or black lead from the meter to the centre of the coil , and to either one of the terminals positive or negative. You want 9500-10000 Ohms, a little less is ok but no more.

What should the ohm reading be on a coil pack?

The ohmmeter should read between 6,000 to 30,000 ohms. If the readings are above 30,000 ohms or below 6,000 ohms, replace the coil pack. Reinstall the coil pack into the engine bay and reconnect all the electrical connectors.

How to test Ford coil on plug ignition?

OK, to test the Coil-On-Plug ignition coils on your Ford car or truck, you need to know what each wire (circuit) does in the connector. Here are the circuit descriptions: Power (12 V) Circuit.

How do you test the resistance of a coil pack?

No resistance tests, you first make sure there isn’t any Crank Sensor codes. Then, with the coil disconnected you put a test light between the connector terminals and crank the engine (Remember to disable the fuel system first). The test light should flash while cranking. Next reconnect the coil connector.

When to test a Ford coil pack with a multimeter?

Any time your ford coil pack starts to fail, you then are most likely seeing the start of your car developing several issues. Therefore, if you suspect that the ford coil pack is defective, you then need to go ahead and have it tested with a multimeter and hence know whether or not it needs to be replaced.

What should secondary resistance be on Ford coils?

1.Measure coil secondary resistance between the corresponding spark plug wire towers on the coil. 2.Resistance should be 12.8-13.1 kilohms. If secondary resistance is not within specification, replace the coil pack.
