With an Ohm meter I ohmed the terminals where the coils sit to the pins inside the module area and found that there is one terminal that all 3 coils ohm out to. At first I thought it might be a common ground, but then I remembered that coils are triggered via ground, so it had to be a common +12v, or at least that's my understanding, is this correct?
Also, people said that it doesn't really matter which terminal I gave +12v or GND, as long as there was each going to each coil. So, technically, even though the coils all share a common +12v (again, my assumption), had I not had this little coil holder thing, I could have just supplied a 12v source to either pin on any coil and a GND to the opposite pin to that respected coil.
Ok so anyway, my question is, with that yellow wire distributed to those coil packs, is it ok to assume thats +12v?
Then, once that's established, the other pin on the coil goes each to a seperate pin in the module area and thus I assume they are ground triggers for the coil? Will these come DIRECTLY off of the Pin #2 of each VB921? If so, am I golden in my setup?
Thanks guys. I sanded the paint off the tops of the coils and renumbered them according to my engines firing order...I think it is correct:
My engine fires 1 5 3 6 2 4, and so I have 1 and 6 on the same coil, 2 and 5, and 3 and 4 on the same coil, for wasted spark of course. Is this correct?
