I recemtly got my 77 280z running and had an alrm installed after the alrm was installed. My Brake light and blinkers stop working.We disconnected the alarm and some of the lights started working but the battery was drained. We found out that one of the wires near the battery were fried and half of the fuses in the fuse box were not getting power. We replaced the wire and the fuses started working but the fuel pump would not shut off even when the car was off and the brake lights stayed on. Someone please help I 've run out of ideas.
