How can I check the resistance of my ignition coil?
You’ll need a digital multimeter to check the resistance levels of your coil. The side terminals of the coil are marked positive (+) and negative (–) and these are where you can measure the resistance of the primary windings.
What should the resistance be on a Delco ignition coil?
This reading of 8.84 does indicate that the coil’s secondary windings are not putting out as much voltage as they should; the minimum acceptable resistance reading here should be 11.00, with approximately 13.5 being normal. Here’s the primary reading on the new replacement GM Delco coil before I installed it.
What happens if there is no spark in the ignition coil?
Hence, without this high voltage, there is no spark and, consequently, internal combustion cannot take place within the engine. Simply put, the bottom line is without spark the engine doesn’t run.
What’s the normal voltage for an ignition coil?
Normal reading on the primary windings is 1.6, but 1.5 is still within the acceptable range, so this by itself doesn’t necessarily indicate a problem.

What does it mean when your ignition coil is orange?
If the spark is orange or some similar color. Either the coil is weak and is going bad or you do not have proper voltage going into the coil. If you have a weak spark coming from the spark plug, lets check the ignition input voltage first. On the plug there is a green and a white wire.
Why does my ignition coil have a weak spark?
If the spark is orange or some similar color. Either the coil is weak and is going bad or you do not have proper voltage going into the coil. If you have a weak spark coming from the spark plug, lets check the ignition input voltage first. On the plug there is a green and a white wire. The White wire is a 12 volt constant.
