To clarify, are you saying that when you remove 12v from the remote wire that the voltage on that remote wire actually goes negative?

Are you placing the black meter probe on the amp's main ground wire when checking this?

Yes. That is what is happening. Black meter lead on main ground with meter set on DC 20v range.

The longer it's on the more negative it goes.

You may have some leaked electrolyte in the area. Wait for the voltage to become significantly negative, with the black on the ground wire, rub the red probe in the board. Does the meter ever show any voltage when not touching a solder pad or area of bare metal?
