dual batteries
I always have a power problem in the winter when snow plowing. I have an 100 amp alt. but thinking of installing two batteries. I have heard this is the ticket, but how to you hook them up?

What kind of power problem do you have? A 100 amp alt should fix most power problems, unless it's a wiring size problem. We had a company pickup we plowed snow with(early 90's Ford f250) and never had any problems.

Additional battery don't give you more power, will give you more reserved power for starting. While engine is running all power comes from alternator.
100 Amps is good value I recomend you increased RPM from actual 650 to 700 or even 750, it will give you almost 25% more power from alternator, OR change the alternator pulley for a smaller one, sometimes difficult to find.

I know what you are talking about as far as the lights dimming, ours did it too. But after years of pushing snow, it never gave us a problem. And I showed no mercy pushing snow with that truck. The blade (Meyers) gave us problems one season, till we found out water had gotten in the hydraulics somehow.

Is this really true? If the demand for power exceeds what the alternator can provide, won't the battery begin to discharge to try to help out? Most starter batteries have amperage ratings far higher than a typical alternator (600 CCA vs. 100A alternator). I'd always assumed the battery was a second power source when the alternator got maxed.

Alternators put out 14.4 +- .5 volts to run the truck and to keep the battery(s) charged. The typical 12 volt battery puts out 12.7 +- .5 volts typically.
So what's happening is the lights are dimming due to a slight voltage drop, not from enough current.
