Maybe, some motorcycles have capacitive ignition, not magnetic.

Negative, COP with internal igniters don't have just one transistor. I mentioned, it's a simplified diagram on the video. Also on these COP with internal igniters, you don't have access to the coil primary for a DMM test, because it had a PCB circuit in between. On a non igniter unit, an Ohm check is just preliminary to detect opens, but won't test a coil. Often times coil windings semi short a couple turns, which is undetectable by an Ohm check. www.autodiagnosticsandpublishing.com/ignition_coil_pulser_tester.html

haha.. ignorant lad! owning the DMM & knowing how to operate it doesn't automatically make you a technician or an engineer 😆😆

COP coil has 3 wires. Ground, B+ and trigger. autodiagnosticsandpublishing.com

Yes unless there's an issue.

Awesome video. People rarely reply to their audience but i noticed you do and that makes one of a kind. I HAVE A 2003 ACCORD V6 with wierd isssues (rough rumning, stalling...). I am marrowing the issue to an electrical issue. Tested the signals at the 3 pin coils yesterday & i see Battery Voltage, Ground and the last pin is 0volts or nearly that. I am wondering what the last pin is supposed to be

Well, you need to test the coils. There's no other way. We make the ZAPPER COIL Tester for that. Here... www.autodiagnosticsandpublishing.com/ignition_coil_pulser_tester.html

Yes, search my channel, ADPTraining here on YT .

I already posted for 4 wire coils, coming on live tomorrow here on my channel. Thanks

Great, count me in.

Your welcome. autodiagnosticsandpublishing.com

Absolutely not. I'm same cases the coils are $95 each. Why replace all coils? Proper diagnostics is the way to go and save.

Highly unlikely it should still spark 🤯

No, ECM provides trigger pulse. Fuse box provides power.

@@ADPTraining Thank you kind sir...

Multimeter has no place here. These are igniter built in coils. www.autodiagnosticsandpublishing.com/VW_Audi_COP_Coil_Tester_Pulser.html

You can just guess & be a parts exchanger. Or you can understand how a component works & then use your logic / diagnostic skills to determine the fault(s) Good luck with that. If you're a shade tree mechanic & go to a junk yard & buy cheap known good parts that's fine. BTW fuel Injectors work on a similar principle & you cannot simply use a multi meter or a test light. A noid light set or a Power Probe 4 are the cheapest way to check certain injectors other than buying an expensive scan tool & a scope.

Ok
