Step and Recliner on Chassis Battery

Is this normal? I've got a few other threads about what led me to discover this. But the bottom line is that my passenger seat recliner and the auto step appear to be connected to the chassis batteries instead of the house batteries. I've removed the chassis batteries to have them tested and while they are disconnected there is no power to the chair or the step...This seems strange to me.

    I just bought the coach a month ago so I don't know how old the batteries are but they certainly look like it's time to change them out. I put a meter on them yesterday (while still installed and connected in parallel) and they both read about 7v. Took them out this morning and they read 11.3v. Dropped them off at Autozone and he was reading 9volts...

    Just got off of the phone with Autozone. One charged fully but tested bad with a load on it and the other wouldn't fully charge so they couldn't test it. So that looks like one issue at atleast!
    there should be a decal on the battery that tells you when they went in service. But if they are not able to charge 1, the other is not far behind. I'd do new quality batteries now. while you are at it, clean all connections including the Neg ground on the frame.
  • I think your setup is normal and the way it should be. The steps are linked to the ignition system to allow them to close when you crank the engine, and come back out when you open the door, regardless of the status of the house batteries.
  • Most Front Drivers and Passenger seats are connected to the chassis battery. Also, the Steps are SUPPOSED to be connected to the chassis battery. Some OEM's connect the Steps to the Coach batteries, which is not good. Doug

    Pretty typical. My first test to see if the chassis battery is dead is, will the step work?
