Correct. My ACE is wired this way.
Power to the brains/control box that's in a right side storage compartment, comes from the chassis battery and the ground comes from the emergency brake (there is a switch that activates when the brake is depressed). The low voltage warning comes from this connection.
Then, there is a about 8 wires that run from the brains to the actual hydraulic pump.
The pump itself gets power from the coach batteries and have a high amp breaker in line.
From what I've read, and experienced, when you get the low voltage warning, you can put it in manual mode and level manually (which I always do anyway, due to the violent nature of the LCI leveling).
I have not been able to really pin down when/why I get the low voltage. I have checked at the control box when it's occurred, and it the voltage was around 11.4. My suspicion is a questionable ground. Maybe the switch on the emergency brake isn't working correctly. I checked the at the chassis battery at was getting the 14.2V or so that you would expect with the engine running, so I don't think it's an alternator problem, which is why I expect a ground.
