I'll tell you one thing if it is draining your battery something is wrong. Do you have an installation manual? All the wires are going somewhere, except of course one of the trigger wires. For me it's been a long process of trial and error. Still havn't got it right.
You should have at least 12V coming off the positive lead ( originally connected to the coil ) to the small red wire on the MSD box. Take a meter to it and see. If not 12V than you will have to cut back the resistor wire until you achieve 12. Also make sure you have a solid ground for the MSD box.
If you get it working or have anyomore problems let me know.
