how can i hook up a 12 volt pump to my Deuce

[appellandscaping]

i am making my deuce dump and i need to know how to hook up the electric over hydrolic pump can anyone give me some ideas

i just ran my 12 volt pump on 24 volts it works great just make sure you use a 24 volt relay...I used a starter relay from a deuce i've been working mine like this for about 7 yrs no problems at all ..

Cat dealers have nice voltage drop boxes you can use to convert 24 to 12, You might also get them at NAPA.

When I built mine to dump I ran 24v to the solenoid and picked up 12v between the batteries to control the solenoid and coils for the valves.

thanks alot guys ill work on it and send pics its really close to beig finished

if it is a big motor like a starter or snow plow pump, just run it on 24volt, it won't care.

Isn't a Deuce just two 12 volt batteries in series which give you 24vdc delivery?

if you pull the power for the pump off of just one battery it will kill both batteries and probably the gen to...there is a serious risk of making one of the batteries explode..when you pull off of just one what happens is that batttery will discharge more than the other .The gen will charge till it sees 24 volts it charges both batteries at the same rate the one that din't get discharged by the draw will get over charged and can explode.i have been running my 12 volt pump on 24 volts for 7 yrs i have dumped hundreds of heavy loads no issues at all...the motor actually runs cooler with 24 than it did with 12 as it runs for half as long to do the job and parts are moving more air when turning .

If he has the same pump as tm america, same specs and everything, I would definitely do it the way he is doing it as he has the track record. If the pump is different, or built by a different manufactor, I would take what he has to say in consideration.

don't know much about anything,but i've been lifting my 11 foot plow with a 12 volt elec.-hyd. dyna-mite pump now for 5 years. still going.

Guys building low riders have been running 12 volt pumps on as much as 48 volts for years ..Any time you have two batteries in series they need to be drawn apon at the same rate and charged at the same rate....Yes they will take a certain amount of uneven discharging and charging ..but this will lead to early failure ...I was running my trailer lights off of just one battery ...This was a small draw but it still caused the batteries to discharge at a uneven rate and killed the battery in less than a year..Of course i thought it was just a bad battery...Then it happened again same battery and again a couple months later...i unhooked the trailer lights from the one battery..no more problems and it has been over two years ..Since 6tls are not cheap i would run the pump and relay on 24 volts and get a voltage reducer to run the soloniods this will be a safe way to do it....or you can add a 12 volt battery and a 12 volt alt to run your 12 volt items...i am in the process of making the brackets needed to add a 12 volt alt to the deuce and to update the 24 volt gen to an alt..MY design is done and has been tested....i made my jig and have 100 of them getting cut out on the plasma table this week ..

Those should be a high demand item. I know I would want one.

any unbalance in load on batteries in series will result in an unbalance in charging. but it will be in an unfavorable fashion. the battery with the load will undercharge and the other battery can be severly overcharged. just don't do it. for 12 volt selenoids you can use a dropping resistor, one for each selonoid. measure the current at 12 volts and use a resistor that will give you the same current at 24 volts. ohms law formulas are on internet.

OK guys. I can tell you after working with electronic engineers as an engineering technician for the last 25 years. I can tell you it is always best to go with experience.

I will withdraw my previous comments. Thanks for the wisdom.
