The most likely reason for a dead battery in a 1996 Dodge Caravan that only produces a clicking noise when attempting to start is a lack of sufficient electrical power reaching the starter motor. This could be due to a faulty starter motor, corroded battery terminals, a weak battery, or a poor connection in the electrical system. It is recommended to first check the battery voltage, clean the battery terminals, and inspect the starter motor for any issues before proceeding with further diagnostics or repairs.

I don't know what "after battery is off" means, but if it is clicking while trying to start, then most likely the starter/solenoid/relay is bad.
If the 1992 Dodge Caravan won't start but makes a clicking noise, it is probably a combination of things. The starter solenoid is making the battery go dead between starts. Replace both and the problem should be solved.
Clean or change wiper fuse, check battery
check your battery then the connections if it still wont start try changing the starter solenoid if possible
When you hear a clicking noise is most likely a battery problem however you stated that the battery was replaced so i suggest you check the condition of your cables look for rust or corrosion etc.
Probably it's a low battery, though it could be a bad starter. You are probably hearing the starter solenoid clicking.
Charge or replace the battery.
A dodge caravan may be experiencing rear brake noise due to needing new brake pads. This may also be due to worn rotors.
Try cleaning the battery cable connections of corrosion.
Does the engine turn over and then make the clicking noise while trying to start, or does it not do anything but make the clicking noise when you turn the key. If its not turning over at all then it might be a battery problem, Try cleaning the battery terminals, and/or charge the battery, Could also be the starter solenoid, but start with the battery first.
Is the battery fully charged? Try jump-starting it.
