battery draining...HELP pls

[67cst]

talk about one problem after another, i guess its expected that you will have little gremlins to work out after a new motor and trans swap etc. everything is the same as it was before the swap ( wiring wise ) except i put a high torque mini starter in. i hooked up the battery cable to the correct post on the starter and also hooked up the purple wire to the post it goes to. the yellow wire going to the old starter i taped up and tucked it back in the loom it came out of, i was told it wasnt needed and it was for the old points ignition. is this correct? could it be the source of the dead battery? it isnt grounding on anything. when attemping to troubleshoot i took the wires off the junction block that is beside the battery bolted to the inside of the fender, anyways when i take the red and black wires off the junction block and hook up a multimeter to them the other end of the multi meter to the positive post on the battery there is a definate flow of current, should there be one? anyone with any ideas id love to hear them, i am pretty stupid when it comes to electrial stuff.

thanks,
