Check your main grounds first. Battery ground and engine to body ground strap. A bad engine to body ground strap can result in the throttle cable taking the load, heating, and melting the casing.

If you're sure the battery is servicable but is discharging uncommanded, you'll need to narrow the leak down to an individual circuit. Use Papajam's wiring diagram and see if you can measure any current across the various circuits (via removing the fuses and measuring any leaking current).

I think the hillbilly-wiring of the starter button has got to go. If the key switch is bad, get a new one and wire it correctly. They're about $100. Maybe someone on the board has a repair procedure, but I don't know of any.

It's also probably a good idea to reroute the power supply of the SPICA Cold Start Solenoid to the output portion of the starter solenoid to take the load off the key switch and keep from robbing current from the starter solenoid. This is a common problem for SPICA cars. See the recent thread dealing specifically with that problem.
