House batteries 2019 Flair

[Mrchuck32257]

Have an unusual problem with house batteries/or slide controller On 2019 Fleetwood Flai. stopped last Thursday evening due to storms in Balt area at Cracker Barrel lot. Opened the bedroom slide that evening with no problem. That night we had heavy rain. Went to retract on Fri morning and the slide wouldn’t move with low voltage warning. engine was started, ebrake on. Check battery voltage on monitor and chassis battery was 13.2 v but the coach or house was zero. I checked battery’s with meter and they were charged to 13.2v. All other components that use 12v house batteries worked, inverter for fridge, 12v lights. We were able to pull slide in using Aux button on dash, but need to find root cause! Monitor stills reads 0 volts. Loose connection somewhere? hidden fuse?

When you checked house battery with the meter, was the engine off? Engine should be off for at least an hour, I believe.
