The alternator was recently replaced (at my request) and six months later the car is starting to fail on the road again.
When I took the car to the dealer they said the alternator was fine. When I took the car to the battery dealer, they said the battery was fine.
I finally hooked a voltmeter up to the DC port, and while I usually read 12.5-14 volts, on occasion at start up it settles in below 12 volts, then slowly starts dropping.
I have been able to determine that if I leave the car running and the fan kicks in, then the voltage jumps to 13.5 and the output voltage seems to be correct for a while.
What else can I test to determine where the issue is?
have the same problem?
