    Is it safe to assume that my truck is set up for snow plow because it has dual alternators? I think one of my alternators is going bad. On my scangauge i run my truck and the batteries stay pretty constant at around 14 volts. When i run my plow up and down like we do, my voltage drops to 12.0- 12.5 volts and it usually takes a fair amount of driving to get the batteries back up to 14. It seems to me that i am losing an alternator. What do you guys think. I have an 04 F350 6.0L

    Put a voltmeter on each alternator, i just had a thread on this in the same section but mine was single alternator. I agree with you, one bad alt if voltage is recovering over time.
