Why does my Z31 FUSE Light Light Up?

There should be no load in the circuit. Jiggle the wiring harness back and forth; if the test light lights up, then there is a short to ground somewhere nearby, possibly where some insulation has been eroded off of a wire. You can also use this method to test other parts of the same circuit, like the switch.
