Battery Disconnect ON

I've noticed that my Intellitec BD1 Battery Disconnect lamp stays on continuously. Before, it would go off when I moved the rocker switch to STORE and I had the MH off AC power. I can hear solenoid(s) clicking when I move the switch in either direction.

Any suggestions why the red lamp always stays on now? Like this, I can't tell if the batteries are disconnected or not (I assume they aren't in that the lamp continues to illuminate.) I installed new solenoids over a year ago and the switch was working properly afterward.

The voltage meter does function correctly.

    Over the years about 99% of the solenoid remote relay power failures I have diagnosed are caused by

    The big number one
    Sloppy control wire terminations and wire routing

    Then
    Garbage grade relays (solenoids)

    Use good wire -- not PVC. Cross link, Hypalon, or EDPM are all good choices.

    Use butt connectors and wire terminals that have heat shrink tubing. Buy an assortment found on eBay.

    If you hear the solenoid clicking, then the solenoid is BAD. Replace it. These are called "latching" solenoids. When you hit Store or USE, the disc inside the solenoid moves to the correct position and stays there. Hence, it takes NO POWER when engaged. OR when disengaged. It is trying to move the disc, but cannot due to failure. IF one of the 5 amp fuses on the solenoid was bad, you would not hear the click. Doug

    If on shore power should they not work from converter even if no battery connected?

    OP, you do have a digital multi-meter of course since you have an RV?
    Use that to see what 12v power is where with the switch open and closed, regardless of the red lamp.

    You also have a chassis batt that might be powering the red lamp?

    Too simple to be true :)

    Like I stated, the batteries are still connected when in STORE mode (I double checked after your response). Where would I begin to look for an answer to this problem. I'll start tomorrow by testing the rocker switch. I'm not very much familiar with this electronic device.

    Thanks for your response.
