how can you tell when your central nervous system is tired and you must wait before training?

Your grip strength is a good indicator. If your grip is failing doing stuff you'd normally do relatively easily, then it's time for a rest day.
Vertical jump height is a good indicator as well, but more useful if you're training more as an athlete.
how the fuck does that work
if your muscles are ok and your cns is tired, what prevents you from lifting?

>what prevents you from lifting?
Your CNS is what makes your muscles actually contract.
What happens is that when your nervous system tells a muscle to contract, it does so by forming a synapse (connection) with the given muscle. In order to do so, it must release so-called neurotransmitters. Over time when you lift really heavy things and keep pushing yourself, the neurotransmitter reserves become depleted i.e. your CNS becomes "tired" and unable to activate your muscles to the full extend.
That's the short and simple explanation.

your muscles are a slave to the slave owner that is CNS
if the slave owner can't smack his whip as hard as he should, the slave will slack

nice explanation... I never thought of this
so are there any products to recharge neurotransmitters faster?
what I'm concerned about is that it's difficult to gauge wehter or not your CNS is tired, I may can you actually "feel" it ?

Nothing stops you from lifting, it just wont be to its full extent. I took a month of once because i went on holiday and came back to the gym stronger than when i left

It's not really something you need to worry about. Some days you just come in to train and the weights will all feel heavy as fuck. Then you know your nervous system isn't properly fired up.
When this happens you can try to do some activation drills (jumps, throws) that may help wake you up a bit. But if that doesn't work, then you're just going to have to accept that you would have been better off taking a rest day. I'll usually quit my regular routine in this case and work on some other stuff, do some accessories, mobility work, pre-hab, ab stuff etc. It's no catastrophe but you won't be setting any personal records on a day like this.
Just have it removed. Really leave humanity behind.

Do you have a longer, slightly more involved explanation? That is very interesting.
