    I'm not sure what those rails look like but on my 2V I hacked off the ends of the rails as much as possible to shorten them then retapped the holes. This was the only way I could get a nice AN...

    Finally some Good News!

    A quick thought while laying in bed. What should/can be the cranking dwell be? If 3ms is too long for normal dwell then what about the cranking dwell of 6ms?

    Yes, I'm measuring the pins of the connector while disconnected from the coil, key on, engine off.

    I just probed each coil connector pin to chassis ground and with a freshly charged battery the (+) pin measures 11.5V on Connectors #5, #6 and #7 and .2V on the (-) pins on #5, #6 and #7.

    This is...

    I agree, but I'm not finding any electrical short in the wiring by probing thus the need to physically review each wire..

    The actual AF values I don't care about at idle but when one bank used to be on average .3-.4 less than the other bank but now it's on average 0.7-1.5 then that indicates something changed.

    Yea, and I think I found it being that pointy solder joint piercing the heat shrink on #5 coil harness. I didn't see if it was on the negative side of the wire but I have to suspect that it was.

    No clue. When it comes to electrical I just do what I'm told as long as it's explained so a 5 yr old can understand it. My plug gap is only about .020.

    Technically the Vampire isn't activated until it hears knock which is why it can be disconnected and the car will run fine. Once it hear knock then it takes over the timing. I doubt it will affect...

    No clue... Things simply started working even #5 coil harness is working just fine although I still have 3 burned up coils.

    Try about half that dwell - Mustang coils hit 8 amps very quickly due to low inductance.

    Hey Matt,
