Need wiring help with 24v vs 12v

[acesneights1]

Had a thought. On my M1008 the plow pump is a Meyers E60. It is slow as heck and the pump only has one battery as a buffer. Is there any reason I could not wire just the pump motor to the 24v side of the batts ? I was told a DC motor doesnt matter but I am not sure of that. What do you guys think ?

Are you talking about sending 24V to a 12V motor?

If you are talking about using the positive and negative from the back battery then you have to account for the fact that the back battery negative is the same electrical point as the front battery positive.

If your pump motor is a negative ground unit and it has the motor case (which is bolted to the vehicle chassis) bonded to the negative input somewhere inside the pump motor then you will melt things.

The same effect as using a non-isolated ground alternator on the passenger side. If the last thing you hook up is your batteries after installing a non-isolated ground alternator on the passenger side you will see a nice welding arc form between the battery post and the battery terminal when you go to connect the front battery negative (assuming that is your last connection).

What I think he wants to do is to run the 12V motor on 24V not run it just off of the rear battery which will result it what you said.

You could hook the pump up to 24V after you isolated the solenoid power from the pump power but you better invest in a triwall of pump motors as you will fry the motor pretty fast. It would be a pretty fast plow though!

Yes run the 12v motor on 24v. I was not sure. I was told by a rebuilder that the starter
Motors in the m1008 a 28mt is the same 12v to 24v and only the soleniod was different so i though if that were true why wouldnt it work on the plow pump motor. Thing is soooo sloooow

Spoke with my auto elec re builder. He said it will cause premature failure but he can get me a 24v motor for the E60 plow so for anyone running a plow setup on a CUCV stay tuned. I will post how it works out.

I beleive the pump motor is isolated but could there be a risk of some sort of issue of them sharing the same ground ?

Make sure you wire it like I have it in my diagram so you don't fry your solenoids, just replace the 12V pump in the diagram with the 24V pump.

You should be fine.
