I'm no tech; but you are going to need a schematic for this one.
You will need to trace the relay circuit and find voltage entering in along at some point that is keying the relay on. Something is giving it voltage when it isn't supposed to get it - obviously. With a voltmeter and a soldering iron, isolating each part and eliminating one by one will expose the problem - but it will be time-consuming and effective.
Other than that, someone else that experience with that unit will have to point out where in particular to look for the problem source...
