Just recently, I’ve noticed that my inverter panel stays lit up when I have the coach in storage with the master switch (in the battery compartment) off and plugged into shore power. I noticed it as I was locking up and noticed the microwave oven front panel was lit up. I’ve cycled the inverter panel on and off but it still stays on in the off position. If I remove shore power it turns off. The panel is labeled “heart interface”. I can upload a pic if that helps. Thanks.
