cavanbound, IF you do unplug the siren make sure you wrap it in a sandwich bag or eqv. so that the connector isn't exposed to the elements. This will prevent the connector and wiring from getting moisture into it/them and causing connectivity/corrosion relating to that connector. You CAN use a good grade of electrical tape, but nowadays I have a hard time receiving a good grade of tape that doesn't 'unravel' when exposed to the elements. It sounds like the typical 'siren' issue, good luck!
