Testing Engine Ignition Coil Pack with a Multimeter
In some cases, a faulty ignition coil can even prevent a vehicle from starting. In order to keep our car working well and smoothly, it is important for us to know the way of testing the ignition coil.
Set up the car
Ensure the car has cooled off from any driving or idling, and after that turn the emergency brake on. Open the hood and detach the negative battery wire attached to the battery end terminal.

Remove ignition coil pack
Search around or on the engine for the ignition coil pack. Disconnect the mounting bolts that are stabilizing the engine ignition coil, and after that take out each coil from the engine place.
Check the ignition coil’s primary and secondary windings to see if the coils need to be replaced.
Examine Primary Winding
Primary winding is composed of heavy wire and acquires direct energy from the battery. Attach the positive and negative leads of the multimeter to the correct terminals on the engine ignition coil. Each terminal is marked with signs related to positive and negative leads, such as a plus and minus sign. Check the owner’s instructions for more guide. Notice the reading on the multimeter and compare this number to the resistance required for the primary winding. If the reading is outside as of the common range, you have to change the resistance coil. In the event the reading is zero, the coil would have shorted out inside. However , if the reading is very high, it represents the coil is open. The engine ignition coil is in working condition if the reading is open.
Check secondary winding
Thinner than the primary winding, it wraps around the coil many times and acquires energy from the primary winding, which is transferred to the spark plugs. Attach the correct multimeter leads to the positive terminal and center pole. If the reading is outside the right range for optimal performance, you have to change the ignition coil.
Handle every issue
Does your car have multiple ignition coil pack? If yes, take out and check each one one by one, take notice of the readings applying a multimeter, after which reinstall or change each one as needed.
Do not skip to examine the spark plugs
Since the ignition coils fail because of faulty spark plugs, you ought to take a look at the condition of the spark plugs too. Poor spark plugs can certainly overburden the ignition coils and overwork them. If you don’t resolve the spark plug issue, the coils are most possibly to fail once again.
