I just bought this car and everything was working great when i bought it. I brought it home and noticed that the electrical connections to the battery were corroded so i took them off, cleaned them and reinstalled. NOW NOTHING WORKS! the headlights work, horn, heater fan but nothing else. There is an alarm installed. I checked underhood fuses by checking continuity, the battery is at 11.8v, i checked the ground to the battery by putting pos (of voltmeter) on battery and neg on engine block and got 10.8v. I have the wiring diagram for the car and everything works thats before the 100amp main fuse, but that fuse "seems" to check out. I tried 2 sets of keys. I hear a relay click when i turn the key but no dash lights come on. I dont understand, im going to continue to look at the wiring harness but how could this happen? all i did was clean the connections. Dead ecu? alarm immobilizer? fried harness? ground somewhere? bad battery?
