Sounds like it's time to replace the battery.

Check the fusible links and miniature fuses-if okay short out the starter motor and see if itll crank the engine

Youll need to replace the battery. Youll need a altenator. Reversing the wires blows the diode in the alt.
This clik click thing is a dead battery.

Backwards hookup blows the diode in the alt. It will need to be rebuilt or u need a alt. The click click is a dead battery most likely this started from this problem. Your battery voltage is to low. Make sure you check all your connections. Ty for using 2carpros
