    Just because it's a 12v motor doesn't mean it won't work on higher voltage. The higher the voltage the faster a motor will spin. Not exactly a good way to do things but it sounds like the previous owners were not happy with the speed/flow of the system. There has to be a combiner or step up transformer somewhere in line for you to be seeing 24v at the motor.

    I unhooked the second battery and still got 24v at the reel motor. Will 24v coming to it burn it up?

    Sounds like there is a step up transformer somewhere in line then. 24v won't burn it up right away, but over time it will definitely shorten the life of the motor if it was not built to handle the higher voltage.

    My other question is to whether this is the same battery bank that starts and runs the truck?

    Are you sure or just assuming?

    There may be two battery banks. Im sure there is a transformer somewhere

    I guess I assumed it was a 24 v system. If not and it is a diesel and you need the 12v for the starting system then it is pos to pos neg to neg for 12v extra capacity.
