Where to buy HEI ignition coil test 3?
IGNITION COIL TEST 3: Verifying Ignition Coil Is Getting 12 Volts. Why The HEI Spark Tester. Where To Buy The Ignition Coil And Save.
What is the primary resistance of a Honda ignition coil?
So I measured the primary resistance between the coil (+) & (-) terminals and got 0.22 ohms, which I think is too low. Checking the secondary resistance between the coil tower (including the spark plug wire because it’s all one piece) and the (+) terminal I got 10 K ohms, which I think is okay.
How is the ignition coil connected to the ECM?
The Bl/y wire is connected to the coil with a spade connector. The wire itself, along with the green one, disappears into a wiring harness. I presume the other end goes to the ECM.
Is it possible to replace the ignition coil?
Normally, the high secondary voltage produced by an ignition coil is quite powerful. You can replace the secondary coil wire on an engine that uses one with an equal length of vacuum hose and the engine will start and run.

How can I tell if my ignition coil is on fire?
Have someone crank the engine and observe the center electrode of the plug — if there’s sufficient voltage reaching the plug, you should see a bright blue spark jump across the gap of the electrode every time that cylinder fires. If you see no spark, the coil is a good thing to suspect next.
