Bench Test Coil

To test the coil s secondary winding attach the test probes to the outer 12 volt pole on the coil and the center pole where the main wire goes to the distributor.

Bench test coil. This bench test is all about the primary and secondary windings of your car. Testing a ignition coil without a meter. Complete info about it can be read here in respect to this how do you bench test an ignition coil. The 12 volt pole is the spot where the power comes into your coil.

Before you begin keep the car manual handy and make a note of the normal reading for each of these two windings. It will be marked with a sign or it might only be indicated by a number. This video describes a simple and easy one man procedure to test if your coil is firing properly. In general the primary winding will have a reading of 0 75 to 0 81 ohms while the secondary winding will have a value of 10 000 to 11 000 ohms.

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.
