i've run the battery down to dead a few times before I got the wiring redone. And unfortunatly the auto parts store's little machine says it checks out and won't replace it


The parts store tester and/or the operator there is wrong. Your battery has a bad cell. If you have another location for the chain in your area, go there and try again. If they will not replace it go somewhere else and buy a battery. The brain damage from chasing this problem is not worth the money!
Something that is often overlooked in ignition noise trouble shooting is that the battery acts as a very large filter capacitor. It takes care of the ripple on the output of the alternator diodes, some of the hash from the coil primary from firing and other voltage spikes from switches turning on and off. A bad battery will not filter this noise out.
