The reading between the spark towers is 12,000 ohms. I have a spare Green Dyna coils that tests out at .2 ohms on the wire terminals and the spark towers is 15,000 ohms. So I'm left to wonder are my coils bad/weak or is it something else I'm overlooking. I know that the Dyna coils are supposed to be @ 3 ohms so I'm wondering if in fact it is also bad. Any ideas??

On the secondary(sparkplug wire ports)side the readings will be between 10.4K to 15.6 k ohms.
Your coils may be failing from heat and/or insulation breakdown.

If the windings are shorted together just beyond the terminals, you could get a zero reading, but it's also possible his meter is just off a tad. If bountyhunter's heat up test raises the resistance, then the coils are shot anyway.

...The spark appears to be very weak....
What voltage is reaching the coil primary terminal?
