That may be your problem right there. Regardless of what you do with the other two wires, do NOT run with the "sense" line disconnected! When you do that, the alternator may think the system is getting 0 volts and increase its output to compensate... thus overcharging the battery.
I'd try connecting the sense line to (in order of preference) the +12 "main junction point" if your car has one, or the alternator's output terminal, or the battery. Connect an indicator light to the light terminal and the ignition +12 (that'll eliminate having to rev the engine to get the alternator going), and go from there.
