Replaced Neg Terminal on 02 Jeep Liberty Now engine won't Crank

The bolt on the stock neg terminal had fallen off, I bought a generic
aftermarket terminal from Auto Zone, replaced it, had to buy a separate
secondary ground to reach after cutting (the circuit has two wires grounding
off of the battery). I get lights, radio, acc but will not turn over. The main
ground is extremely hard to access otherwise I would have changed the
whole cable. Is there a reason this cable won't work with an aftemarket
terminal??

Any help is appreciated thank you for your time.
