[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?

    Verify the low voltage right at the converter output. Once confirmed then replace. Yes virtually all newer converters are made to operate fine without a battery.

    Which converter do you have. Most of the newer converters don't have to have a battery attached, but some of the older ones do require a battery.

    However, the converter voltage should be above 13.2v under all conditions, so it very well could be a bad converter.
