The primary ignition coils should have at least 10 amps of power running through it. Generally, this is far less power than what flows through the secondary ignition coil.

Does the coil on a1969 Chevy have the same voltage on the plus and - side of the coil when the ingintion is on?
When you take a voltage reading at the coil with ignition on and the ignition points are open you would get the same reading on both + and - .
My 97 Honda accord ex rpm needle is fluctuating while im driving but the transmission is shifting fine?
Hey, I have been reading that it is most likely the ignition coil that went out. I have the same problem and just ordered a new ignition coil... you should try that...is an easy fix
Where's the ignition coil in 87 Pontiac grand am?
The ignition coil is down between the firewall and the back of the engine
Where is ignition coil 3 located on a 2003 dodge ram?
The ignition coil should be inside the distributor behind the cap. Remove the distributor cap screws, remove the cap and you will see the coil.
When should you replace your ignition coil?
Replace it only if it becomes defective.
No spark Ford Escort what should I do?
Please check your spark plugs,wires,distributor and rotor or the ignition coil module. My '93 LX has an ignition coil module.
Where is the ignition coil on 1990 740gl Volvo?
This model probably has the Regina engine. The ignition coil should be mounted on the drivers side fender well close to the firewall.
Where is the ignition coil on a 96 civic cx hatchback?
The ignition coil is inside the ignition distributor.
Is an ignition module the same as a ignition coil?
No. The coil provides the spark and the module tells the coil when to spark.

Hope This Help.TESTING Ignition Coil TestThe ignition coil must be diagnosed separately from the rest of the ignition system.Primary resistance is measured between the two primary (low voltage) coil terminals, with the coil connector disconnected and the ignition switch off. Primary resistance should be 0.3-1.0 ohms.On Dura Spark ignitions, the secondary resistance is measured between the BATT and high voltage (secondary) terminals of the ignition coil with the ignition OFF , and the wiring from the coil disconnected. Secondary resistance must be 8,000-11,500 ohms.If resistance tests are okay, but the coil is still suspected, test the coil on a coil tester by following the test equipment manufacturer's instructions for a standard coil. If the reading differs from the original test, check for a defective wiring harness.Ignition Coil Primary Circuit SwitchingInsert a small straight pin in the wire which runs from the coil negative (-) terminal to the TFI module, about 1 in. (25mm) from the module.WARNINGThe pin must not touch ground!Connect a 12 VDC test lamp between the straight pin and an engine ground.Crank the engine, noting the operation of the test lamp. If the test lamp flashes, proceed to the next test. If the test lamp lights but does not flash, proceed to the Wiring Harness test. If the test lamp does not light at all, proceed to the Primary Circuit Continuity test.Ignition Coil ResistanceRefer to the General Testing for an explanation of the resistance tests. Replace the ignition coil if the resistance is out of the specification range.Ignition Coil Secondary VoltageDisconnect the secondary (high voltage) coil wire from the distributor cap and install a spark tester between the coil wire and ground.Crank the engine. A good, strong spark should be noted at the spark tester. If spark is noted, but the engine will not start, check the spark plugs, spark plug wiring, and fuel system. If there is no spark at the tester: Check the ignition coil secondary wire resistance; it should be no more than 5,000 ohms per foot. Inspect the ignition coil for damage and/or carbon tracking. With the distributor cap removed, verify that the distributor shaft turns with the engine; if it does not, repair the engine as required. If the fault was not found proceed to the Ignition Coil Primary Voltage test.Ignition Coil Primary VoltageAttach the negative lead of a voltmeter to the distributor base.Turn the ignition switch ON and connect the positive voltmeter lead to the negative (-) ignition coil terminal. Note the voltage reading and turn the ignition OFF . If the voltmeter reading is less than 90 percent of the available battery voltage, inspect the wiring between the ignition module and the negative (-) coil terminal, then proceed to the Ignition Coil Supply Voltage test.Ignition Coil Supply VoltageAttach the negative lead of a voltmeter to the distributor base.Turn the ignition switch ON and connect the positive voltmeter lead to the positive (+) ignition coil terminal. Note the voltage reading then turn the ignition OFF . If the voltage reading is at least 90 percent of the battery voltage, yet the engine will still not run; first, check the ignition coil connector and terminals for corrosion, dirt, and/or damage; second, replace the ignition switch if the connectors and terminal are okay.Connect any remaining wiring.REMOVAL & INSTALLATION Carbureted EnginesDisconnect the battery ground.Disconnect the two small and one large wires from the coil.Disconnect the condenser connector from the coil, if equipped.Unbolt and remove the coil.Installation is the reverse of removal.Fuel Injected EnginesSee Figures 1, 2, 3 and 4Fig. Fig. 1: Disengage the high tension wire by pulling on the connector boot-fuel injected enginesFig. Fig. 2: Separate the wiring harness connection at the coilFig. Fig. 3: Unscrew the coil from its bracket mountFig. Fig. 4: Remove the coil from the enginePulling on the connector boot, disconnect the high tension lead at the coil.Disconnect the wiring at the ignition coil.Remove the ignition coil-to-bracket attaching screws, then remove the coil.To install:Install the coil, tightening the screws to 25-35 inch lbs. (2.8-4.0 Nm).Connect the ignition coil wiring harness and the high tension lead.
Does the ignition coil need to be grounded on a 2003 Chevy Astro?
It is advisable to have the ignition coil grounded on a 2003 Chevy Astro. This should especially be done when you are working on spark plugs and wires.Ê
Where is the ignition coil located in a 1998 tercel?
The 1998 Toyota ignition coil is located on the firewall, in the engine compartment. The ignition coil can be found on the passenger side of the firewall.
