Hi
I don't use a pre-charge relay - I have an old kettle element that I use as a pre-charge resistor - when the voltage gets up there I switch the main contactor

I suggest you wire it all up carefully - use a manual pre-charge if you have cooked the resistor

And see what happens!

With my controller voltage does not matter but I know with some controllers they will sense the voltage and refuse to play if it's too low
