4100 Open Gray Water Tank

[tglass]

The primary pump on my gray water tank quit running.  I've verified that the float switch in the bottom of the tank is in the on position but that's all the diagnosis I've done, I'll try and direct connect the pump to a 12v battery tomorrow  Anyone else have to repair/replace this pump?  I'd like to exhaust all possibilities before spending $300 plus on the replacement.
Thanks

After draining the tank I found that a wire on the float switch was broken.
