1995 civic dx d15b7 all stock

i started the car and the battery light wouldnt turn off


i checked the voltage at the battery with the car running 13.54-13.67
battery with the car running headlights on 13.11-13.23
turn the headlights off back at 13.54-13.67

same voltage directly at the alternator with the car running.


car off at the battery was 14.56 held the same voltage for a couple minutes while i had the meter on it


so i think its safe to drive...so we hop in and go to target about halfway there i put the blinker on it and the speedo bounces from 70 down to 0 the same as the blinker does...the gauges dim down...rev it up to about 5k and its good all the way to target and i check the voltages back at target and it was all the same...made it home with no problems at all

any suggestions?

this is a retarded problem to have

:edit: battery terminals were tight and not coroded

so it seems as if the charging system is working great

 

Make sure your alternator harness is plugged in first of all, as a precaution.

I would remove the alternator and have it load tested. Even though the alternator puts out the required voltage, the amperage may be way out of spec. This is caused by a failed diode(s) in the alternator, and can come along with a very annoying whining sound.

The stator has 3 (sometimes 4) feed wires to the battery, coupled into a WHT or WHT/RED wire to the battery, because of the rotation of the armature/stator. If one of them failed, it will still make the 13.8v required, but with much less current. If the voltage regulator fails, your voltage will fall, hence the name voltage regulator.
