Mine does (well, did) the exact same thing. The plow is stealing so much voltage (amps) from the battery and the rectifier/regulator is fighting too juice the battery up after the loss. The stock rectifier puts out 27 amps. The ignition/fuel injection and whatever else is on, is stealing amps too. That shows up on the volt gauge as a drop. The charging system can't keep up with this loss. I could blade for about 45 minutes, with heat headlights ect on, before my battery would die. With the 65 amp alternator, I installed (thanks RD) my problem is solved. Yep, a bigger battery will help. But you may have to give it a break to charge, when blading. Mine always has a battery tender on it when it sits, just to keep the battery fresh.
