Hi. Just changed-out my spark plugs and wanted to see if my coil packs are still good. I found a site or 2 that mention how to test them with an ohm meter, so I pulled-out my multimeter and tested mine. I figured, even if I didn't know what I was looking for, at least I can see if there's a difference from one coil to the other. And there was. One coil gave me absolutely no reading whatsoever, the other was giving me infinitive resistance across certain leads. Is there a way to test these properly and what resistance should I be getting?? THANKS!!
