Intellitec BD1 Battery Disconnect

I have a 2012 Newmar Bay Star motorhome (model 3002) that's equipped with an Intellitec BD1 battery disconnect located over the entrance door to connect or disconnect the coach batteries. As a full-timer the coach is plugged in (1 month or longer) for extended periods of time. The red indicator light between the switches on the right side of the panal stays "On" then after a few days it goes "Off" and has a faint glow to it. After a few hours the light goes back "On" to being full red again. Then a few days later it'll go back to the faint glow etc. This light continually cycles back and forth from full "On" to a faint glow. This happens all the time yet the 12V lighting in the coach is fine although occasionally the lights will suddenly get very bright. Newmar says this is not normal operation and that there's a problem. Any ideas/suggestions? You thoughts are appreciated.

Assuming the switch is in the USE position rather than STORE, the indicator is showing the presence of 12v power. When the light goes out, power has (supposedly) gone away. ON the surface it seems that you are losing power and then having it come back on, so my first step would be to check with a voltmeter to verify system voltage as the light goes through its cycle. If the voltmeter agrees that 12v battery power is coming and going, you would seem to have a charger or battery issue. If the voltmeter shows that 12v power remains stable, then the problem is the electronics in the disconnect unit.

Agree with Gary you can also check the main 12v fuse panel, maybe near your load center, and check all the wiring connections make sure screws are tight against the stranded wires on both the + & - terminals.
Road vibration will loosen screws.
