My charger wont charge. I cleaned the red wire contact in the DC socket. Checked the fuse in the charger. Still nothing

What year cart and model charger is it? Did you clean the outside of the terminal on the carts charger receptacle where the red wire contact need to make it's connection? Does the chargers relay click when you plug the charger into the cart?

If your pack voltage is below 28v it will not come on without individually charging the batteries to bring them up a little.
