I'm noticing that when the truck is at idle and the turn signal or hazards are on, the voltage meter dips below 12 volts at the same time I hear the relay for the turn signal clicking. So I was wondering if the alternator is going back. I did the simple multimeter test where you take the voltage at the battery terminals with the car off, then start the car and check the voltage again. With the car off, it was 12.71 volts. Once the car was started, the voltage went up to 13.88 volts. I know that I'm supposed to be looking for 14 volts. 13.88 volts sounds close enough.
If the alternator is ok, then the voltage dipping at the gauge could be attributed to a dirty connections along the circuit?
