My car have no power at all. No lights, no horns, and no ignition when I tried to start. What cause this?:confused: :confused: :confused: :confused:

Jump the car with jumper cables, see if everything comes back. Check battery and loose rusted connections. There is a main fuse or several, lets go with the simple first!

Jump that baby!

1. Ensure battery is fully charged.
2. Clean battery terminals and connections.
3. Check all under-hood and under-dash fuses with a test light or multimeter. See link below:
