I have a 36V battery that apparently has a problem with the "input" connector, that is there's no indication it's being charged. However, it can be charged through the "output" connector. Is this a problem?

Depends on what's wrong with the input connector and how it's wired to the pack's BMS, if there is one. If the BMS has separate charge and discharge connections, then charging through the discharge connectors won't balance the pack when charged, or could overcharge some of the cells before the charger shuts off. If the BMS uses the same connections, then that would mean the wiring to the charging connector may have issues, but charging through the discharge connector should work.
 
It may charge through the input, but without bms safety features for overcharge. You will have to watch it and stop it in time.

So don't do it all the time, and NEVER do it inside the house.
