Bilge pump switch doesn't turn on bilge pump

Hi, have a new (to me) 2010 188 Sundeck Sport and the bilge pump works if I go up a hill on the trailer and I guess the float kicks the pump...but it doesn't work if I push the bilge pump switch. If this is a fuse, where is it located? Any other suggestions or hints at how to troubleshoot this?
Thanks in advance.

    There are two power feeds to the bilge pump. One is when you turn on the master power switch, this feeds the manual function which is not working. The other is a fuse at the battery which feeds the automatic float switch. It is "hot" at all times. This one is apparently OK. Check the dead one working back from the dash switch until you find the open circuit.
