I see you said you have the OD relay feeding from the coil terminal. You need to be certain you have adequate size wire from the ignition switch to the coil and there is not a resistor ahead of your feed to the coil and relay.

If you want to by-pass all the circuitry feeding the relay you can install a temporary heavy wire from the battery post to the relay. Temporarily by-passing the ignition shouldn't cause any problems because the relay only energizes when speed is reached to the road or the relay grounded.
