The battery(s) ground on the "NEG" post of the battery. Did you remember to re-attach the grounding wire?

If you grounded the "POS" post you re-installed the battery(s) back-words. It may blow the fuse on the converter/charger if left that way.

If two 12v batteries, are they connected in parallel? Two 6v volts must be in series.
