1993 Ford F-150 mileage: 65,000. I am on my third battery in this truck. The voltmeter seems to set at a different voltage from one start up to another. Sometimes around 11 volts, sometimes up around 14. It doesn't always fluctuate with engine speed, but sometimes it will drop when at idle. I'm wondering if I have a alternator problem or a voltage regulator problem?

You are right the voltage regulator or alternator may be failing. But first check the drive belt for the alternator. Is it glazed and slipping? Is it tightened properly? Also, check the ground wires. Are they making a good Connection?
