How to check coil packs with a voltage meter?
This checks the secondary resistance. Set your ohmmeter to the 10 ohms range, and touch the terminal B+ (usually the center prong on the coil pack electrical connector) with one of the meter test leads, and touch the corresponding coil prong on the electrical connector with the other test lead.
What should the ohms be on a coil pack?
Set your ohmmeter to the 20000 ohms range. Turn on your meter and touch the spark plug wire terminals on one of the coils with the meter leads. You may get a reading between 5000 to 15000 ohms, depending on your particular model.
How can I tell if my Nissan coil is still running?
If the coil has a plug-in connector instead of the studs, unplug the connector for the coil after releasing any locking tab on the connector. Place one lead from the multi meter on the negative post or terminal of the coil. Place the second lead on the positive post or terminal and note the reading on the meter.

How can I tell if my coil pack is working?
Fortunately, there is an easy way to test the coil packs in your vehicle and make sure they’re working as they should. You need to use ohm meter to test the coil pack for continuity. Make sure you have the approximate ohm values for the coil pack.
If the coil has a plug-in connector instead of the studs, unplug the connector for the coil after releasing any locking tab on the connector. Place one lead from the multi meter on the negative post or terminal of the coil. Place the second lead on the positive post or terminal and note the reading on the meter.
How do you unplug a multi meter coil?
