I've got a Western 7 1/2' Pro Guard on a 92 Ford F250. Problem is, the plow drains electrical system. Battery is new. Alternator is 60amp (reman)just replaced for 2nd time in a year. Plow Electrical motor runs good and does not drain under no load (not hooked to pump). Hooked to pump, the plow angles and raises fine (angles a little slow to left - but not bad). However, within 10 minutes of use, electrical system will drain and truck will stall. You can get the truck to stall real quick if you angle the plow to one side and continue to angle it after its reached max. Alt meter in truck will drains from 12 to near eight everytime you angle and then recovers pretty quick to 12 but like I said extended angling or moderate to heavy use will kill the truck's electrical. We then have to jump start it and baby it (raise/angle in short bursts) - or park it altogether). Otherwise truck runs great - no problems with heater or lights draining system. HELP - Need advice. I think it may be the new alternator is bad. Others? MUCH APPRECIATED!
