This is my sons TT that I ma helping with. I assume voltage is good at battery...but we all know what happens when we assume ??. Next step check voltage at battery.
There is nothing to indicate it is the battery .....
Check the voltage is a level charging voltage where there is a problem, and work back from there (if you are lucky the fuses may actually be accurately labelled). It's most likely related to the new converter install. If it was backwards you should have blown the reverse polarity fuses. If the converter is not working then why would the lights not work yet other things do work .....since you seem to have incandescent lights they would work even at very low voltages (with a different colour).
