possible problems might be:
converter is not receiving 120 vac power
converter reverse polarity fuses are blown
battery shutoff switch has batteries disconnected fro converter
resettable 12 circuit breaker has tripped
batteries not cabled properly for either series or parallel
battery is installed backwards
corrosion in battery cables
loose or open connection in converter to battery power path

Just remember 12 volts is just a name for a system. When a converter is powered up there needs to be a minimum of 13-13.2 volts at it's output terminals or all you are reading is battery voltage.
As for a $10 meter, splurge and spend $20. Amazing how much more accurate the difference can be. Remrmber that the difference betwern charge modes is only a few "tenths of a volt". Cheap meters can have that much variation built into their accuracy before taking any readings.
