I chave 2 batteries that are fully charged and work fine. I cleaned all the terminals on the batteries. I followed the red wire back from the number one to a long cylinder on the stern side of the 1992 7.4 mercruiser big block. I there was three wires comming of (the starter I think). I took them off and cleaned that as well. Still one loud click when I turn the key. Any suggestions. I took these three pics. I dint know if it will help.
