How do you test a 12 volt ignition coil?
Turn on the multimeter and set it to the “ohms” function. Insert one of the multimeter’s probes into the center opening of the coil, contacting the metal terminal inside the coil. Touch the second probe of the meter to the ignition coil’s grounding terminal. The meter should read 6,000 to 15,000 ohms.
How to test the coil of a relay?
Therefore, the resistance should be anywhere between 288Ω to 352Ω. You check the relay coil’s resistance by taking a multimeter and placing it on the ohmmeter (Ω) setting and placing the probe leads of the multimeter on the 2 terminals of the relay’s coil. It doesn’t matter which probe is placed on which terminal.
What should the meter read on a ignition coil?
The meter should read between approximately 0.4 and 2 ohms. If it does not, the coil’s primary winding is faulty. If the coil checks out test the main coil wire, that was removed from the distributor, for shorts.
When does the induced voltage of a coil increase?
If the current increases then we get flux build up which induces a voltage of its own. The sign of this induced voltage is always such that the voltage will be positive if the current into the coil increases. We say that the induced voltage will opposethe externally applied voltage which made the current change (Lenz’s law).

Is the ignition coil on my Honda CT-70 working?
I am experiencing a No-Start/No-Spark condition on my “Factory-Original” 1973 Honda CT-70 3-Speed Automatic. I tested the ignition coil with a multi-meter.
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.
