If you removed the cable while the car was running - bad news! You could have killed the ECU.

If the car was running why did you remove the cable?

Here is the simple procedure to test your charging system:

a) Car not running - battery should read about 12.4 - 12.6 volts.
b) car running - check voltage at the battery terminals: it should read something around 13 - 14 volts.

For more sophisticated test go to Autozone. They test your system for free.



Good luck,
Sam

I would pull out fuses one by one and check them for the continuity. Fuse may look fine but still be bad.

Good luck,
