No electric power 97 5.9
 

I have a 97 5.9 stock. After 3 days of rain the cab was soaked. And the batteries were dead. When I tried to recharge, the charger kept clicking on and off no charge on batt. No IGN. No lights nothing. Is it possible that I may have destroyed the batteries. I am a fair wrench, but less than novice electrician. Can someone give me a starting point to diagnose this problem. Thanks capnmoe.
