If it is shorted closed, does the horn still function? IF the horn functions when you press the touch pad, it is not closed.
We would not be able to assume a voltage drop (amperage loss) unless the power went somewhere.
Otherwise the parasitic drain should drop battery voltage in about 4-6 weeks parked.
Be sure you also turn off your auto bilge switch, which is the default when parked.
Please let us know what you find and get back to us.
