How To Quickly Diagnose The Sneaky Weak Ignition Coil

Описание к видео How To Quickly Diagnose The Sneaky Weak Ignition Coil

A quick video to rule out or confirm a weak ignition coil, the symptoms of which present themselves as a fuel delivery issue.
I filmed the spark of a weak coil and a good strong coil which in person you can visually see the difference, but the differences are very subtle and hard to see in the video. So when checking to see if you have spark with a weak coil, you'll see that you do indeed have spark, but under load the spark isn't strong enough to keep up with increased fuel/air mixture and the engine bogs down or quits above idle under load. I'll show how the engine has a hard time starting and running with the weak coil, but immediately starts and runs strong and smooth with the good coil.
I describe the symptoms and behavior of the weak coil, so if you're experiencing these symptoms swap out the coil which is quick and easy to just jumper one in. You'll quickly rule out or confirm a weak coil. If it's not the coil, it's time to check fuel pressure, and fuel filters, or run circuits in the carburetor.
