    your alternator bad or one bad/weak battery? maybe go to the local parts store and have them checked they do it on the truck anymore.

    could also be bad connections is there any green fuzzy stuff any where from the bat's to the plow motor or maybe even bad wire's from the alt.. but also could be a bad cell in the battery or bad wire's any where in the system... check every thing over...

    also parts store's can not tell if you have a bad cell in a battery some time's it will come up ok when it really isn't...

    Disconnect and clean all connections. Put some of that red battery spray on the terminals to prevent corrosion. See what that does for you. But you're probably going to have to replace a battery or two.

    If you're voltmeter is reading 14 the alternator is fine.

    I bet you have some water contamination in your fluid, your motor is working overtime trying to pump it through the system..check it out and check your filters as well, they may be clogged up.

    sounds like an intermittent problem with the alternator to me.

    You may still want to have your batteries tested. They still might both read 12 volts but one of them might be bad and can't handle a draw. That will show a big drop when operating your plow.

    if the batteries arent maint free get a 4 dollar bat tester and test the water in them you will know for sure if they are good or not....

    This was happening to me the beginning of this season. I had drained and refilled the system with blue hydraulic fluid. Could not figure out what was going on. Then I read a post from one of the pro's (B&B I think it was) regarding fluid and these same symptoms and he said whenever a plow came in with these symptoms, first thing he did was drain the system and fill with Meyer M1 - so this is what I did and the past two storms the needle barely drops. Looking at a quart of M1 fluid I noticed this is even printed on the bottle. I know the stuff is expensive but it def. works better in my plow than the thicker after market stuff so I learned my lesson. Plow is back to moving the way it should be with hardly any draw. I didn't read the entire thread so my apologies if it's been mentioned already.

    im thinking its my fluid. gonna do a drain flush and fill with m1 sometime soon. my only other option was motor getting worn out and pulling too much power.
