[SOLVED] Bad converter? Low voltage

The voltage in our class A's converter drops as low as 8.2V (measured with a cigarette lighter voltmeter) with a DC laptop adapter attached. Causes the charger to stop and the laptop not to charge. It currently has no house battery connected, though there is a starter battery. After some time the laptop charger stops trying and the voltage stabilizes at 10.9V. Is this a sign of a bad converter, or is this because no house battery is attached?

    Amp-L-Start. combiner over the isolator will allow the WFCO to charge and maintain the chassis battery.

    Or if the "isolator" is supposed to connect and pass power to the chassis.... it would be a good time to replace it.

    are isolators (diode based) units even a thing anymore? aren't they all solenoid based now?

    if i replaced every battery that made it to 11.1, i'd be poor, recharge it and move on.
