    Hi.
    This is happened this morning.i heard low voltage alarm on my inverter ,started engine ,everything came back up (14,7;volts on inverter screen ) so i shut the engine after 5 min udling.
    About 1 hr later i started it again ,heated up started driving and noticed my splitter in cigarette lighter goes on and off. (Not much load on it 1 phone 1 dashcam).
    Later on splitter died completely ,tried next plug no luck. Stopped at rest area to check fuses ,all fuses are good ,this time my sleeper cigarette lighter plugs and interior lights in cab and sleeper died. Everything else is working.
    Have anyone had similar issue ?
    Kw t660 2010.
    Thanks

    Behind the driver side left kick panel there is a low voltage disconnect module. I believe it is made by Delco or Sure. There will be 2 larger power wires bolted to it along with a plug with a few wires. That module is bad. Remove both large wires and bolt them together or replace module.
