I don't think that's quite what you are describing though. The coil and injector power were both connected to the same bus which could be connected to either or both batteries thru solenoids. Separate CB's for Primary, Secondary, Leading, Trailing. Can you connect the EC2 directly to one battery thru a CB for testing? I think I remember seeing that you had swapped EC2's and still had the problem. Is there any possibility something is connected to one of the NC pins on the EC2? Those might do something internally. I don't know that for certain but Tracy does. :) Bob W.
