Not enough power for electric spreader

    Has anyone had to come up with a solution for running out of electric power in your plow truck? My new sander has two electric motors and a vibrator. Its not spreading effectively and the plow moves very slowly while the sander is on. I ran another wire from my altenator to the 2nd truck battery which helped a little. Should I get a bigger altenator? give the sander its own battery? Or just replace my truck batteries which are original-2007.

    Never move the plow when running the sander.

    I just switch to electric, i hope this isn't a issue, i would have stayed with gas...

    I would change batteries, maybe add a battery for spreader it self...

    I run a snow ex 8500 on a single battery, stock alternator and wiring and a plow on one truck and never have a problem. This truck probibaly spreads 50+ ton/year.

    Replace the 2 in the truck and add a 3rd for the spreader also, then you have a spare battery to.

    Probably your 2007 batteries are getting a little weaker, (though I have never had a battery better than an OEM one). Alternator should be plenty big on that truck, though you can probably figure out what it is either by tag or option code. Electric motors do draw alot of power, my 3/4hp leeson draws 58 amps! I added a 3rd battery to my truck in the salter, since it was a gas to electric conversion it had a tray location anyways. I'm still not thrilled with the power draw these days, wondering if my motor is wearing and drawing more--bought a clamp meter to find out, haven't had a chance to. Also purchased a spare motor just in case. My problem is when it starts to work really hard it wants to slip the alt belt. Considering going to dual pulleys.

    Wow! Is it typical of a sander to draw that much power?

    I had the same problem. I kept killing batteries. I had to upgrade alternator. I bought from https://www.dcpowerinc.com/. It was pricey but now I run the spreader with 2 motors, strobe, plow and never have a problem or run my batteries down.

    That number comes off the tag on it, I've never actually measured it. I would imagine that is the max draw its supposed to pull under heavy loaded startup?

    Most salters only have 1/3 or 1/2hp electric motors, so they would draw alot less, I was converting and replacing a 10.5hp gasser, so I went for the overkill motor lol... keep in mind many salters have more than one motor, mine only has the one.

    Clean and tighten all of your terminals. Bad connections raise hell on battery's.

    It might have something to do with 7 year old batteries.
