An absence of spark from just ONE ignition coil points to a bad coil. Just as the title says, How do you test an ignition coil using an ohm meter? Testing the COP coils in your 3.0L Ford Escape (or 3.0L Mazda Tribute) can be a challenge, since three of them are under the intake manifold plenum (this article can be applied to several other 3.0 Ford models).The three that are underneath the intake plenum are the COP coils for cylinders #1, #2 and #3 (cylinder #1 is the one closest to the serpentine belt). It just pushes in place, but make sure it is all the way in or it may come loose when the engine is running. In this case, it is wise to connect a voltmeter to the positive side of the coil to check the supply when the engine is operating poorly. The 3.0-ohm coil should be used on PerTronix Ignitors installed on four- … Conventional coils read about 1.2 ohms. The coil wire connection has a longer snout and will require some modifying of most wire sets. Reinstall the negative battery cable on the negative post of the battery. Right now, 6 are giving me readings alike, but 2 are not giving me a reading from primary to secondary at all. Ford Coil - Six Volt - This Ignition Coil is an exact replica of the original used in Ford Tractors, 1950 to 1964. 3 0 obj 5 0 obj I bought a new pack and checked the primary resistance on it, and it measured the same thing.

I'm trying to diagnose a coil pack on a 2003 Mazda B3000 with the Ford 3.0 V6. The total ignition resistance in the 6 volt ignition system was about 2.2 ohms with the engine warmed up (1.7 ignition resistor HOT plus 0.5 coil). The coil looks like a black cylinder with a center wire similar to a spark plug wire and two side posts with nuts and wires attached. endobj 4 0 obj The primary resistance was fine at 0.8 ohms, but all three secondary resistances were high at 15 K-ohms. Based on those values, our ignition circuit will be consuming about 24 watts of power when the points are closed. I need to know the coil resistance specs (primary and primary to secondary) for the coil used in a 98 Ford 4.6 litre that is equiped with the 8 individual coils. The primary winding of your ignition coil is the first to receive voltage from the battery, so we'll follow its lead and test the primary first. Also, mount the coil so the coil wire is as short as possible to keep resistance low. endobj Note the resistance reading on the ohmmeter. Keep the other lead on the positive post of the coil. Place the test leads from the ohmmeter on the side terminals, one on each side. The severity of the symptoms vary according to which of the ignition coils are failing. An ignition coil that has the wrong internal resistance often exacerbates this condition and leads to a poor-running engine for which you can find nothing wrong. Most of that is being dissipated by the resistor. If the readings are within range, reinstall the wires and retaining nuts on the side posts, being sure that they go back on in the same position they were in before you removed them. Remove the retaining nuts and all the wires attached to the side terminals on the coil as well. It replaces: 8BA12029, D0PF12029A, D3PF12029AA, E8T12029BA. Note: If all of the ignition coils aren’t delivering spark, the issue is likely with the control side (primary side) of the ignition system, rather than a single ignition coil.
