2005 Pilot just died while driving. Put a meter on the battery and it was low...so I assumed alternator and/or battery. Removed battery and determined it was bad. Replaced and put the meter on. 12.6V with engine off. With engine running, the voltage didn't change. I assume the alternator would have brought it up to around 13-15V. Increasing RPM increased voltage which would lead me to believe the alternator works.

The running voltages-should be atleast 13.5-15.5 volts-have the alternator load tested-if the no.6 and no.9 fuses checks out-
