What should resistance reading be on ignition coil?
Switch the meter’s resistance range to the 20K-ohm setting and attach the negative (black) meter lead to the center terminal of the coil. The reading here should be 11.00 or better, with 13.49 being about normal.
How many ohms does an ignition coil have?
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.
What should secondary coil resistance be on 12 volt car?
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. 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.
Where are the electrical contacts on an ignition coil?
Position the leads of the ohmmeter on the poles of the primary coil. The distributor will have three electrical contacts – two on either side and one in the middle. These may be either external (jutting out) or internal (sunken in) – it makes no difference.
How do you test an ignition coil with an ohm meter?
Set the dial on an ohm meter or multi-meter to 20k ohms. Insert the positive lead on the ohm meter into the end socket or the metal hoop on the spark plug wire. Put the negative lead of the tester onto the metal armature portion of the ignition coil.
What should the ignition coil reading be on a push mower?
A working ignition coil will give a reading of between 2.5 – 5 k ohms. Set the positive lead of the multi-meter in position where the spark plug would usually insert – ensure it has made good contact. Place the negative lead onto the metal body of the ignition coil – again ensuring it makes proper contact. Look for the reading on the multi-meter.
Switch the meter’s resistance range to the 20K-ohm setting and attach the negative (black) meter lead to the center terminal of the coil. The reading here should be 11.00 or better, with 13.49 being about normal.
How do you test an ignition coil with a spark plug?
Touch the red lead on the ohm meter to the spark plug connection and touch the black lead to the armature on the ignition coil. Lay the ignition coil on a work surface. Set the dial on an ohm meter or multi-meter to 20k ohms. Insert the positive lead on the ohm meter into the end socket or the metal hoop on the spark plug wire.
