i have a 2001 honda civic dx 2 dr. i swapped the alternator and checked the battery it checked out. the car turns on normally nd runs great. but i remove the negative and the car dies. something is not letting the battery charge. can someone please help me out!!!!

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,

i removed the wire to chack the alternator. i was told thats how u can check it. thnx i will try that procedure out today and just to be sure ill also take it to autozone. do u think it will be something with the fuse box if it isnt the ecu??

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

Good luck,

Sam

the charge was fine it turned out being a problem with the fuse box. thnx for the help.
