How do I check the coil on my 8n to verify it is OK?


A digital multimeter is required for testing the resistance levels of the ignition coil. The terminals of the coil are going to be marked "negative" and "positive," and these are the two points where the resistance of primary winding can be measured. Step 1: Prepare the multimeter
To check a 12 volt coil, set the multimeter to at least a 200 Ohms setting. Attach both leads of the meter to the coil-terminals with black to the negative terminal and red to the positive one.
Step 2: Test the resistance
The normal, acceptable range for a standard 12-volt car is 1.5 to 1.7 Ohms. See if the reading is within this range.
Step 3: Test the secondary coil resistance
Set the meter to 20K Ohm setting, and attach the leads to the ignition coil's center terminal. The reading for secondary-coil resistance should be 11, because if it is lower, that's the reason why sparks are not appearing

The Distributor Ignition (DI) system is controlled by the Powertrain Control Module (PCM).

The Distributorless Ignition System (DIS) is controlled by the Powertrain Control Module (PCM).

Testing The Ignition Coil

  1. Remove the ignition coil(s).
  2. Using an ohmmeter, check the resistance between the primary terminals on the underside of the coil. The resistance should be 0.50-0.90 ohms.
  3. Check the resistance between the secondary terminals. It should be 5000-10,000 ohms.
  4. If the coil failed either test, replace the coil.
If the coils(s) are good check the ignitions leads by measuring their resistance. (Multi Meter required.) If the coil(s) and leads are good

WHAT SHOULD THE PRIMARY AND SECONDARY READ WHEN CHECKING TO SEE IF THE COIL IS ANY GOOD?



Testing an Ignition Coil

This testing procedure is valid for most automotive coils. Using an ohmmeter, check the resistance between the side terminals of the coil. Do this with all of the wires to the coil disconnected. You should see 0.75 to 0.81 ohm of resistance. Then check the resistance between either side terminal and the center high tension terminal. The reading should be 10,000 to 11,000 ohms. Any significant deviation from these numbers would indicate that the coil is defective.

Can I test an ignition module on an onan engine with a volt, ohm or amp meter?


well sure you can, allthough if you have allready replaced the coil and plug , i can't see why you'd need to , it's the last thing there is to replace , but if youd like to anyway , just ground the black lead of volt meter anywhere on engine thats not painted or rusty , hold red lead on - side of coil (its the one with half the battery voltage on it) and turn engine over slow as possible you should see the volts rise and fall as it turns over , if not the ign module is not working
also i question why does this have a condenser if it has electronic ign ? cant say id ever seen that before .

What should a multimeter read on a continuity test on the coil packs? i'm getting 1.9,1.7,1.7


The multimeter can read the resistance and if it is not open or shorted out, I'd say that your readings are in the normal range, comparing each resistance with each other + or - 10%.

I looked up the resistance readings on my online resource, but they did not list it specifically.

I looked up the following on autozone.com:

There are 3 dual-tower ignition coils that are part of the ignition control module (ICM). The ICM contains coil driver circuits that command the coils to operate. The Powertrain Control Module (PCM) controls each dual-tower ignition coil by transmitting timing pulses on the ignition coil control circuit to the ICM for the proper coil to enable a spark event.
  1. Inspect the spark plug wires for proper orientation.
  2. With the ignition OFF, remove the fuel pump relay.
  3. Crank the engine and test for a strong spark on each cylinder spark plug wire using a suitable spark plug tester. Ground the companion cylinder spark plug wire of each cylinder when it is tested.

    If a strong bright blue spark is present on all of the cylinders, remove and inspect all of the spark plugs for proper torque, proper gap, wear, damage, and fouling. Replace the spark plugs if necessary. If there is no spark on any of the cylinders, test the ignition voltage circuit of the Ignition Coil Module (ICM) for an open/high resistance or short to ground, or test the ground circuit of the ICM for an open/high resistance, or a faulty ICM. The wire circuit resistance should measure less than 3 ohms. If there is no spark on any of the cylinders, or spark is weak or intermittent, test the IC circuit for an open/high resistance, or a faulty ICM. The wire circuit resistance should measure less than 3 ohms. If spark is present on one or more of the cylinders, inspect and test the spark plug wires for arching, cuts, rubbing on other components, and proper resistance. If all tests are normal, then the system is operating correctly.

Where is the ignition coil located?


For test:
  1. Follow the coil wire from the center terminal on the distributor cap to the end at the ignition coil. Make sure that the transmission is in Park (AT) or Neutral (MT) and that the ignition is turned OFF .
  2. Separate the wiring harness connector from the ignition module at the distributor. Inspect for dirt, corrosion and/or damage. Reconnect the harness if no problems are found.
  3. Attach a 12 volt DC test light between the coil TACH terminal and an engine ground, then crank the engine. If the light flashes or is continuous:
    1. Turn the ignition switch OFF .
    2. Detach the ignition coil connector on top of the coil and inspect for dirt, corrosion and/or damage.
    3. Using an ohmmeter, measure the ignition coil primary resistance from the BATT to the TACH terminals.
    4. The ohmmeter reading should be 0.8-1.6 ohms. If the reading is less than 0.8 ohms or greater than 1.6 ohms, the ignition coil should be replaced.
    5. Using an ohmmeter, measure the ignition coil secondary resistance from the BATT terminal to the high voltage terminal.
    6. The resistance should be 7,700-10,500 ohms. If the resistance is less that 7,700 ohms or greater than 10,500 ohms, replace the ignition coil.
For Removal:
  1. Disconnect the negative battery cable.
  2. Detach the coil electrical connector(s).
  3. Unfasten the retainers, then remove the ignition coil from the vehicle.
  4. Installation is the reverse of the removal procedure.

Hope helped with this.

did you do a spark test?
This could be a number of things, your crankshaft sensor, coils or ignition module.
check the coils
  1. Remove the ignition coil(s).
  2. Using an ohmmeter, check the resistance between the primary terminals on the underside of the coil. The resistance should be 0.50-0.90 ohms.
  3. Check the resistance between the secondary terminals. It should be 5,000-10,000 ohms.
  4. If the coil failed either test, replace the coil.

I need to know how to test the ignition coil on a 1995 jetta


to test the coil you must use an ohm meter and remove the wire connections from the coil, first test the coil from B+ to the center coil wire tower, read the Resistance on the coil and write it down next test between the positive post and to the negitive post read the Resistance next test the negative side to the center post or tower read the resistance there should be no more than 2000 ohms resistance on any test and if it reads 0 resistance it means it's shorted and needs to be replaced, be sure to set the select lever to it's highest ohms resistance level before testing.

P1350 Ignition Control System

Ok, these codes are signaling a malfunction within the Ignition control module. it is sending way to many signals to the coil. i recommend testing the coil for damage and irregular resistance. i will explain how to do this below. i would replace the module as well. The control moduel is Located Under hood, center, rear engine area, above valve cover, mounted in base of ignition coil pack

Ignition Coil Test Procedures__

Ignition Coil Resistance

* with the key off and the battery lead to the ignition coil disconnected, use an Ohmmeter to measure the primary and secondary winding resistance of the ignition coil. when checking the resistance across the windings, pay particular attention to the meter reading. if the reading is out of specifications, even if it is only slightly out, the coil or coil assembly should be replaced.
* To check the primary windings, calibrate an ohmmeter on the X1 scale and connect the meter leads to the primary coil terminals to test the winding.

5d041b0.jpg

* An infinite ohmmeter reading indicates an open winding. The winding is shorted if the meter reading is below the specified resistance. Most primary windings have a resistance of 0.5 to 2 ohms, but the exact manufacturer's specifications must be compared to the meter readings.
* To check the secondary winding, calibrate the meter on the X1,000 scale and connect it from the coil's secondary terminal to one of the primary terminals.


813a25f.jpg
# A meter reading below the specified resistance indicates a shorted secondary winding. An infinite meter reading proves that the winding is open.
# In some coils, the secondary winding is connected from the secondary terminal to the coil frame. When the secondary winding is tested in these coils, the ohmmeter must be connected from the secondary coil terminal to the coil frame or to the ground wire terminal extending from the coil frame. Many secondary windings have 8,000 to 20,000 ohms resistance, but the meter readings must be compared to the manufacturer's specifications. The ohmmeter tests do not indicate such defects as defective insulation around the coil windings, which causes high-voltage leaks.
