Center ballast empty pump not working.

I have a 2010 obv with only the center ballast. The problem is it will not empty. The empty pump works when I plug it into the fill plug. When I put my meter on the empty plug and turn it on it shows 12 volts. If I plug the pump in it shows 0 volts when it's turned on. Any help would be greatly appreciated.
Thanks Rodney

Never mind found it!! :D The wiring going into the five amp fuse holder was not making a good connection.
