With nothing to lose, I started isolating elements by disconnecting the
trigger wires. There was no change in the leakage current - it wasn't
the switch that was bad. In addition to the heavy motor-current wires
going to the PCB, there was a much lighter (24ga maybe) wire.
Unsoldering that stopped the leakage. IOW, the leakage was internal to
the board.
 
It was 10 years old & much used, so I got my money's worth. It was also
a favorite tool, so another one is going to be ordered; a
latest-and-greatest one.
