While the possibility is quite remote, the new battery could be bad. As
long as you hve the time, you mght as do the test just to be sure.
You could hook up a tail light bulb in between the disconneted battery
terminal and the battery lead. If it glows, then something is drawing
current. Then you can start unplugging things to isolate the fault.
