While testing my fuses using a logic probe (test light which has 2 alligator clamps which connect to both positive and ground), I'm getting a ground reading (green light instead of red) on several of my fuses. The fuses are for brake lamps, parking lamps, headlamps, O2 Sensors, injector circuit, ign, and others I can't recall. Is that normal?

Yes, this is normal, the tool with show a ground to the system is not activated because the system is connected to ground when the power is not on. Let me know if you have any other questions, use 2CarPros anytime.
