Question about 2002 Kia Optima
The battery is good, but no power going through to anything. There is acid build up on the posotive side of the battery.
Disconnect the black battery cable, then the red one. Clean both the cable terminations and the battery terminals with a wire brush to remove all corrosion. You can also buy a spray to neutralize any acid residue. When the connections are clean, reconnect the battery - red first, then black. Tighten firmly, but be careful not to strip the threads. Finish by sealing with a protectant spray. Note this is a different spray, not the cleaner mentioned earlier.
