...I have two WD45's...on one the wire from ignition is connected into + terminal on the coil. On the other, the wire from the ignition is connected to the - terminal on the coil... Can someone please tell me which is correct? (Both tractors are 6 volt positive ground,) Thanks...Dan

If both are truly POSITIVE ground, the wire from the distributer back to the coil should be the same or on the + post of the coil.
