Bad grounds cause some very interesting problems. I remember working on a big rig truck working with a test light. I had power going through the firewall from the engine compartment but my tester showed all the wires were dead on the other side of the firewall until I ran a jumper wire to the cab to make sure my test light was grounded. I'm a big fan of jumper wires.
