If you are pulling the wire from the board and measuring the wire to ground voltage, you should actually get 12 volts or whatever your battery voltage is because the wire will still be connected to the battery positive through the relay coil. The voltage should still ALL be there until you ground the wire to trigger the relay.

Measure the resistance to ground on the terminal of the board the wire was connected to if that is where you are disconnecting it. Maybe you are getting a ground through the "Battery Condition Meter" if your system has that. My manual's schematic indicates it is optional. Mine has one over that pantry/vacuum cabinet but IIRC it is not functional unless I turn the system monitor on.
