The converter had nothing to do with threpair. The engine has a missfire that is making the light flash. This may be the reason for the failing converter to start with.
Do not ever disconnect the battery like that. The light would have cleared itself after it passed its own self test without effecting the monitor status.
Get the code checked by a shop this time and find the exact failure.
