24 vdc Hydraulic Pump

24 vdc Hydraulic Pump

It’s hardly noticeable but we made a significant change to the hydraulic system that operates our steering.  We replaced the hydraulic pump that operated on 12 vdc.  The problem is there are many systems on the car that operate on 24 vdc. The car has two 12 vdc main power batteries wired to produce 24 vdc.  When the 12 vdc pump would run, it drained only one battery.  Between runs, this became a problem, because we now had difficulties charging both batteries to full power.

The old 12 vdc system looks just like the new 24 vdc. Same footprint.
