Every time i read where someone has just replaced their battery I always like to bring up the obvious caution. Make sure you have the battery connected up correctly.
The easiest way to tell is to find the markings on the battery case that says "NEG" or the symbol that shows "-". Then follow the cable that is connected to this terminal and make sure it goes to the trailer frame ground connection that will be very close to the battery terminals.
Having a battery connected backwards may result in some fuses blown in the trailer which doesn't allow the battery to be charged.
If your battery cables are BLACK and WHITE colors then the BLACK cable goes to the positive terminal and the WHITE cable goes to the negative terminal.
If your battery cables are RED and BLACK colors then the RED cable goes to the positive terminal and the BLACK cable goes to the negative terminal.
