Hi and welcome
Any chance that you initially connected the positive to the negative terminal?
If yes, then you might have burned out a fusible kink,
Check the fusible link at the starter.

No power anywhere? Or just don't crank? Check the battery voltage at the battery then at the cable ends , you did wire brush the terminals battery and cables? I would also suspect fusible link issue if 12v at cables.
I get it. I have hated Side-Post since their invention.
However.
What type of Top-Post cable terminal did you switch to? Some require melting some solder over copper with extreme heat.
Others are simply a cheap clamp that you hope conducts electricity.
Either way, that connection is likely the cause of your issue.
Had you accidently hooked up the battery backwards with a complete circuit, then damage could occur.
Had you just hooked up one side, POS or NEG, nothing would happen.
Inspect really close, the new cable terminal you just installed.
