Hi there guys,this 2004 civic after I replace the alternator and check the battery voltage I only see 12.6 volts. I think it should be around 13.5 all the connections the belt tenssion are ok, could this a bad battery that is no holding charge.

Apparently, the alternator wasn't the cause of the charging problem. Test for power at the main terminal of the alternator with the KEY OFF.
What do you have?

Did you check fuse 19 (80 amp) in the under relay box?
Did you check fuse 4 (10 amp) in the dash fuse box?

Even thought the voltage regulator is inside the alternator, the PCM controls the output of the alternator based off information it receives from the electrical load detector.

Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.
